cc201e47ba libweston: prevent double weston_output_enable()
Enabling an already enabled output is an error, at least with the
current implementation.

However, disabling an output that has not been enabled is ok.

Cope with the first and document the second.

7f340ff895 libweston: specify weston_output::enabled
It was ambiguous what this flag meant - it did not mean whether the
backend is considering this output to be enabled, because
weston_output_destroy() unsets it while deliberately not calling the
backend disable() vfunc.

Perhaps the most clear definition is with respect to the output's
assignment in the pending vs. enabled output lists. There is also a whole
bunch of variables that are allocated only when enabled is true.

Since the flag is related to the list membership, set and clear the flag
only when manipulating the lists.

Assert that weston_compositor_add_output() and
weston_compositor_remove_output() are not called in a wrong state.

v2:
- talk about "list of enabled outputs"
- clear 'enabled' in weston_compositor_remove_output() earlier

e952a01c3b libweston: move asserts to add_pending_output()
weston_compositor_add_pending_output() is the point through which all
backends must go when creating a new output. The enable and disable
vfuns are essential for anything to be done with the output, so it makes
sense to check them here, rather than when actually enabling or
disabling.

Particularly the disable vfunc is rarely called, so this gets the check
better excercised.

f0ca79639e libweston: let add/remove_output handle the lists
A weston_output available to the compositor should always be either in
the list of pending outputs or the list of enabled outputs. Let
weston_compositor_add_output() and weston_compositor_remove_output()
handle the moves between the lists.

This way weston_output_enable() does not need to remove and
oops-it-failed-add-it-back. weston_output_disable() does not need to
manually re-add the output back to the pending list.

To make everything nicely symmetric and fix any unbalancing caused by
this:
- weston_output_destroy() explicitly wl_list_remove()s
- weston_compositor_add_pending_output() first removes then inserts, as
we have the assumption that the link is always valid, even if empty.

Update the documentations, too.

v2:
- talk about "list of enabled outputs"
- keep wl_list_remove in weston_compositor_remove_output in its old
  place

eca5cca561 Account for very large repaint window misses
At the bottom of weston_output_finish_frame(), code exists to account
for flips which have missed the repaint window, by shifting them to lock
on to the next repaint window rather than repainting immediately.

This code only accounted for flips which missed their target by one
repaint window. If they miss by multiples of the repaint window, adjust
them until the next repaint timestamp is in the future. This will only
happen in fairly extreme situations, such as Weston being scheduled out
for a punitively long period of time. Nevertheless, try to help recovery
by still aiming for more predictable timings.

2cd87fe8d7 compositor-drm: Fix disabling cursor plane
commit a7cba1d4cd changed the way
the cursor plane is setup.  Previously it was pre-emptively set
disabled for the next frame, and that would be changed at next
frame time if the cursor plane was to be used.  It was changed
to be disabled at plane assignment time.

We disable the use of planes entirely by setting disable_planes to
a non-zero value, which bypasses all calls to assign_planes - so
if the plane was set-up in the previous frame it will retain its
state post-disable.

This leads to desktop zoom leaving the cursor plane in place when
it sets disable_planes.

This patch clears any stale cursor plane state from the redraw
handler if disable_planes is set so drm_output_set_cursor()
will do the right thing.

08d4edf20d compositor-drm: Rename drm_sprite to drm_plane
We make the differentiation where planes are an abstract framebuffer
with a position within a CRTC/output, and sprites are special cases of
planes that are neither the primary (base/framebuffer) nor cursor plane.

drm_sprite, OTOH, contains nothing that's actually specific to sprites,
and we end up duplicating a lot of code to deal with them, especially
when we come to use an entirely plane-based interface with atomic
modesetting.

Rename drm_sprite to drm_plane, to reflect that it's actually generic.

No functional changes.

205c0a018c compositor-drm: Clean up page_flip_pending path
page_flip_pending is only be set when do a pageflip to a newly-rendered
buffer; if the flag is not set, we have landed in the start_repaint_loop
path where the vblank query fails, and thus we must pageflip to the same
buffer.

This test was not sufficient for what it was supposed to guard:
releasing framebuffers back. When using client-supplied framebuffers, it
is possible to reuse the same buffer multiple times, and we would send a
framebuffer-release event too early.

However, since we have a properly reference-counted drm_fb now, we can
just drop this test, and rely on the reference counting to prevent
too-early release of client framebuffers.

page_flip_pending now becomes exactly what the name suggests: a flag
which indicates whether or not we are expecting a pageflip event. Add
asserts here to verify that we never receive a pageflip event we weren't
expecting.

f30a18c1c3 compositor-drm: Introduce fb_last member
Previously, framebuffers were stored as fb_current and fb_pending.
In this scheme, current was the last buffer that the kernel/hardware had
acknowledged displaying: a framebuffer would be created, set as
fb_pending, and Weston would request the kernel display it. When the
kernel signals that the request was completed and the hardware had made
the buffer current (i.e. page_flip_handler / vblank_handler), we would
unreference the old fb_current, and promote fb_pending to fb_current.

In other words, the view is 'which buffer has turned to light?'.

This patch changes them to a tristate of fb_last, fb_current and
fb_pending, based around the kernel's view of the current state.
fb_pending is used purely as a staging area for request construction;
when the kernel acknowledges a request (e.g. drmModePageFlip returns 0),
the previous buffer is moved to fb_last, and this new buffer to
fb_current. When the kernel signals that the request has completed and
the hardware has made the buffer current, we simply unreference and
clear fb_last, without touching fb_current/fb_pending.

The view here is now 'which state is current in the kernel?'.

As all state changes are incremental on the last state submitted to the
kernel, even if the hardware has not yet been able to make it current,
this simplifies state tracking: all state submissions will always be
relative to fb_current, rather than the previous
(fb_pending) ? fb_pending : fb_current.

The use of fb_pending is strictly bounded between a repaint cycle
(including a grouped set of repaints) beginning, and those repaints
being flushed to the kernel.

fb_current will always be valid between an output's first repaint
flush, and when a disable/destroy request has been processed. For a
plane, it will be valid when a repaint cycle enabling that plane has
been flushed, and when a repaint cycle disabling that plane has been
flushed.

fb_last is only present when a repaint request for the output/plane has
been submitted, but not yet completed by the hardware.

This is the same set of constructs which will be used for storing
plane/output state objects in future patches.

2667e9e399 configure: replace HAVE_LIBDRM with BUILD_DRM_COMPOSITOR
HAVE_LIBDRM was used as a condition for the launcher infrastructure to
call libdrm.so functions. It was set by an independent test for libdrm,
which would silently continue if libdrm was not found. It was assumed
that if you enabled a feature that used libdrm at runtime, the test for
that feature would imply that HAVE_LIBDRM is also set. This was quite
subtle.

The only feature that actually uses libdrm.so at runtime is the DRM
backend. No other backend needs the libdrm calls in the launcher
infrastructure.

Therefore to simplify things, stop using HAVE_LIBDRM and use
BUILD_DRM_COMPOSITOR instead. If you enable the DRM compositor, you
automatically also get libdrm support in the launchers.

There are still things depending on LIBDRM_CFLAGS and LIBDRM_LIBS, so
the test cannot be removed completely.

compositor-wayland: Refactor struct wayland_output::name usage
struct wayland_output::name was used but never initialized.
Also zxdg_toplevel_v6_set_title was only called for windowed outputs,
and some compositors let you see the client's name even when it is
fullscreen (GNOME Shell's Activities menu for example).

So rename struct wayland_output::name to struct wayland_output::title and
precompute it on wayland_output_create_common(), so it can be later used
on xdg's set_title and frame_create.

v2: Move zxdg_toplevel_v6_set_title() before the wl_surface_commit()
as per Quentin Glidic's suggestion.

This is implemented by storing the absolute time for the next repaint

05df8c16ec Change boolean repaint_scheduled to quad-state enum
repaint_scheduled is actually cleverly a quad-state, disguised as a
boolean. There are four possible conditions for the repaint loop to be
in at any time:
  - loop idle; no repaint will occur until specifically requested, which
    may be never (repaint_scheduled == 0)
  - loop schedule to begin: the loop was previously idle, but due to a
    repaint-schedule request, we will call the start_repaint_loop hook
    in the next idle task
  - repaint scheduled: the compositor has definitively scheduled a
    repaint request for this output, which will occur in fixed time
  - awaiting repaint completion: the backend has not yet signaled
    completion of the last repaint request, and the compositor will not
    schedule another until it does so

All but the first condition were previously conflated as
repaint_scheduled == 1, but break them out into separate conditions to
aid clarity, backed up by some asserts.

3615ce1955 Don't delay initial output paint
On startup, we cannot lock on to the repaint timer because it is unknown
to us. We deal with this by claiming that the moment of entry into the
repaint loop is the moment a frame returned, causing finish_frame to
delay our initial repaint to (refresh_time - repaint_delay), typically
around 9ms of utterly wasted time.

Add an explicit stamp == NULL, to determine that we are just beginning
our repaint loop, that the timings are in fact totally invalid, and that
it would be beneficial to repaint the output immediately. This will only
trigger when the display had previously been disabled or the previous
state is unknown, e.g. at startup, or coming back from DPMS off.

11ae2a3036 compositor-drm: pageflip timeout implementation
Weston will not repaint until previous update has been acked by a
pageflip event coming from the drm driver. However, some buggy drivers
won’t return those events or will stop sending them at some point and
Weston output repaints will completely freeze. To ease developers’ task
in testing their drivers, this patch makes compositor-drm use a timer
to detect cases where those pageflip events stop coming.

This timeout implementation is software only and includes basic
features usually found in a watchdog. We simply exit Weston gracefully
with a log message and an exit code when the timout is reached.

The timeout value can be set via weston.ini by adding a
pageflip-timeout=<MILLISECONDS> entry under [core]
section. Setting it to 0 disables the timeout feature.

v2:
- Made sure we would get both the pageflip and the vblank events before
  stopping the timer.
- Reordered the error and success cases in
  drm_output_pageflip_timer_create() to be more in line with the rest
  of the code.

v3:
- Reordered (de)arming of the timer with the code around it to avoid it
  being rearmed before the current dearming.
- Return the proper value for the dispatcher in the pageflip_timeout
  callback.
- Also display the output name in case the timer fires.

v4:
- Reordered a forgotten timer rearming after its drmModePageFlip().

75487c2560 compositor-drm: Try to preserve existing output routing
Previously in picking CRTC -> encoder -> connecting routing, we went for
the first triplet we found which claimed to work.

Preserving the existing routing means that startup will be faster: on a
multi-head system, changing the routing implies disabling both CRTCs,
then re-enabling them with a new configuration, which may involve
retraining links etc.

Furthermore, the existing routing may be set for a reason; each
CRTC/encoder is not necessarily as capable as the other, so the routing
may be configured to stay within such device limits.

Try where possible to respect the routing we pick up, rather than
blithely configuring our own.

4f3cad7828 compositor: damage pending subsurfaces when committing them
When a client changes the subsurfaces state, we need to damage
them so the result is visible. We do that by flagging the surfaces
when the state changes and causing damage when committing the
state. This prevents normal repaints from considering these changes
until a commit has happened, and allows the client to atomically
schedule several changes.

This fixes the subsurface_z_order test, which is now marked as expected
to succeed.

We had two non-pkg-config check paths in the configure script, to
support XCB functionality used before XCB had had an accompanying
release: xcb_poll_for_queued_event (released in 1.8, 2012), and a
usable XKB event mechanism (released in 1.9, 2013).

Convert the former to a version-based hard dependency, and the latter to
a version-based soft dependency. This avoids two compiler checks.

fb4869d628 compositor: Assign new views to the primary plane
When we create a new view, assign it to the primary plane from the
beginning.

Currently, every view across the compositor will be assigned to a plane
during every repaint cycle of every output: the DRM renderer's
assign_planes hook will either move a view to a drm_plane, or to the
primary plane if a suitable drm_plane could not be found for the output
it is on. There are no other assign_planes implementation, and the
fallback when none is provided, is to assign every view to the primary
plane.

DRM's behaviour is undesirable in multi-output situations, since it
means that views which were on a plane on one output will be demoted to
the primary plane; doing this causes damage, which will cause a spurious
repaint for the output. This spurious repaint will have no effect on the
other output, but it will do the same demotion of views to the primary
plane, which will again provoke a repaint on the other output.

With a simple fix for this behaviour (i.e. not moving views which are
only visible on other outputs), the following behaviour is observed:
  - outputs A and B are present
  - views A and B are created for those outputs respectively, with SHM
    buffers attached; view->plane == NULL for both
  - current buffer content for views A and B are uploaded to the
    renderer
  - output A runs its repaint cycle, and sets keep_buffer to false on
    surface B's output, as it can never be promoted to a plane; it does
    not move view B to another plane
  - output B runs its repaint cycle, and moves view B to the primary
    plane
  - weston_view_assign_to_plane has work to do (as the plane is changing
    from NULL to the primary plane), calls weston_surface_damage and
    calls weston_surface_damage
  - weston_surface_damage re-uploads buffer content, possibly from
    nowhere at all; e508ce6a notes that this behaviour is broken

Assigning views to the primary plane when created makes it possible to
fix the DRM assign_planes implementation: assign_planes will always set
keep_buffer to true if there is any chance the buffer can ever be
promoted to a plane, regardless of view configruation. If the buffer
cannot be promoted to a plane, it must by definition never migrate from
the primary plane. This means that there is no opportunity to hit the
same issue, where the buffer content has already been discarded, but
weston_view_assign_to_plane is not a no-op.

893b936f9a Remove DPMS-on when going offscreen
Forcing DPMS on when we lose our session may force an expensive modeset
operation, which is pointless if the next consumer (another compositor,
or the console) is going to do a modeset. These should force DPMS on
regardless.

This actively causes problems for the DRM backend, in that it may
actually require a repaint to set coherent state for DPMS off -> DPMS on
transitions, which is very much not what we want when going offscreen.

As DRM is the only backend which actually implements DPMS, just remove
this call.

f33e104865 compositor-drm: Remove open-coded weston_compositor_wake
This always changes the state to ACTIVE when we enter the session,
whereas the previous implementation preserved the state (i.e. if state
was SLEEPING on exit, it would be restored to SLEEPING, but also with a
repaint). This seems more helpful behaviour, however: if you enter a
session, it's probably in order to interact with it.

Certainly, it's best for the vast majority of users (and
the project) to require an input device to be present, as
to avoid frustration and hassle, but for those brave souls
that so prefer, this patch lets them run without any input
device at all.

This introduces a simple configuration in weston.ini:
  [core]
  require-input=true

True is the default, so no behavioral change is introduced.

In a gstreamer pipeline, the support of the WL_SHM_FORMAT_YUV420 by

c3d2f960d2 weston: Port X11 backend to new output handling API
This is a complete port of the X11 backend that
uses recently added output handling API for output
configuration.

- Output can be configured at runtime by passing the
  necessary configuration parameters, which can be
  filled in manually, obtained from the configuration
  file or obtained from the command line using
  previously added functionality. It is required that
  the scale and transform values are set using the
  previously added functionality.

- Output can be created at runtime using the output
  API. The output creation only creates a pending
  output, which needs to be configured the same way as
  mentioned above.

Same as before, a single output is created at runtime
using the default configuration or a configuration
parsed from the command line. The output-count
functionality is also preserved, which means more than
one output can be created initially, and more outputs can
be added at runtime using the output API.

v2:

 - Fix wet_configure_windowed_output_from_config() usage.
 - Call x11_output_disable() explicitly from
   x11_output_destroy().

v3:

 - Remove unneeded free().
 - Disallow calling x11_output_configure more than once.
 - Remove unneeded checks for output->name == NULL as that
   has been disallowed.
 - Use weston_compositor_add_pending_output().
 - Bump weston_x11_backend_config version to 2.

174448a91b weston: Port Wayland backend to new output handling API

- Output can be created at runtime using the output

However, the backend can behave both as windowed backend
and as a backend that issues "hotplug" events, when
running under fullscreen shell or with --sprawl command
line option. The first case was covered by reusing
previously added functionality. The second case required
another API to be introduced and implemented into both
the backend and compositor for handling output setup.

enabled manually using weston_output_enable().

v2:

 - Fix wet_configure_windowed_output_from_config() usage.
 - Call wayland_output_disable() explicitly from

 - Get rid of weston_wayland_output_api and rework output

4690c56abc libweston: Add initial output API for windowed outputs configuration
This adds new plugin-specific API for configuring outputs
on "windowed" backends, such as X11, wayland/non-fullscreen

its configuration is very similar). It can be used from

It also supports creating additional outputs on the mentioned
backends.

 - Rename output_configure() to output_set_size().
 - Document return values.

a01ab6d525 libweston: Add more functionality for handling weston_output objects
This patch implements additional functionality that will be used
for configuring, enabling and disabling weston's outputs. Its
indended use is by the compositors or user programs that want to
be able to configure, enable or disable an output at any time. An
output can only be configured while it's disabled.

The compositor and backend specific functionality is required
for these functions to be useful, and those will come later in
this series.

All the new functions have been documented, so I'll avoid
describing them here.

v2:

 - Minor documentation improvements.
 - Rename output-initialized to output->enabled.
 - Split weston_output_disable() further into
   weston_compositor_remove_output().
 - Rename weston_output_deinit() to weston_output_enable_undo().

 - Make weston_output_disable() call two functions mentioned
   above instead of calling weston_output_disable() directly.
   This means that backend needs to take care of doing backend
   specific disable in backend specific destroy function.

v3:

 - Require output->name to be set before calling
   weston_output_init_pending().
 - Require output->destroying to be set before
   calling weston_compositor_remove_output().
 - Split weston_output_init_pending() into
   weston_compositor_add_pending_output() so pending outputs
   can be announced separately.
 - Require output->disable() to be set in order for
   weston_output_disable() to be usable.
 - Fix output removing regression that happened when
   weston_output_disable() was split.
 - Minor documentation fix.

v4:

 - Bump libweston version to 2 as this patch breaks the ABI.

gl-renderer, simple-dmabuf-v4l: fix dmabuf y-invert
Invert the Y_INVERT flag for the EGL import fo dmabufs. This fixes
weston-simple-dmabuf-intel to show the same image on both GL-composited
and with direct scanout on a hardware plane. Before, the image would
y-flip when switching between these two cases. Now the orientation also
matches the color values written in simple-dmabuf-intel.c.

The GL-renderer uses the OpenGL convention of texture coordinates, where
the origin is at the bottom-left of an image. This can be observed in
texture_region() where the texcoords are inverted if y_invert is false,
since the surface coordinates have origin at top-left.  Both wl_shm and
dmabuf buffers have origin at the top-left.

When wl_shm buffer is imported with glTexImage2D, it gets inverted
because glTexImage2D is defined to read in the bottom row first. The shm
data is top row first. This incidentally also means, that buffer pixel
0,0 ends up at texture coordinates 0,0. This is now inverted compared to
the GL coordinate convention, and therefore gl_renderer_attach_shm()
sets y_inverted to true. This causes texture_region() to NOT invert the
texcoords. Wayland surface coordinates have origin at top-left, hence
the double-inversion.

Dmabuf buffers also have the origin at top-left. However, they are
imported via EGL to GL, where they should get the GL oriented
coordinates but they do not. It is as if pixel 0,0 ends up at texcoords
0,0 - the same thing as with wl_shm buffers. Therefore we need to invert
the invert flag.

Too bad EGL_EXT_image_dma_buf_import does not seem to specify the image
orientation. The GL spec implied result seems to conflict with the
reality in Mesa 11.2.2.

I asked about this in the Mesa developer mailing list. The question with
no answers:
https://lists.freedesktop.org/archives/mesa-dev/2016-June/120249.html
and the thread I hijacked to get some answers:
https://lists.freedesktop.org/archives/mesa-dev/2016-June/120733.html
which culminated to the conclusion:
https://lists.freedesktop.org/archives/mesa-dev/2016-June/120955.html
that supports this patch.

simple-dmabuf-v4l is equally fixed to not add Y_INVERT. There is no
rational reason to have it, and removing is necessary together with the
GL-renderer change to keep the image the right way up. This has been
tested with VIVID.

compositor-drm: Stop sending uninit data to the kernel
Valgrind noticed that we send uninit data to drmModeAddFB2.  While
the kernel should never read this (because of the plane format),
it's probably still nicer to zero the data before we send it.

weston-launch: Only run a login shell for new sessions
This way, the environment is correctly preserved for weston. Since
commit 636156d5f6, clearenv() is only
called when we open a new PAM session, so it makes sense to only use a

Introduce libweston-desktop
libweston-desktop is an abstraction library for compositors wanting to
support desktop-like shells.

The API is designed from xdg_shell features, as it will eventually be
the recommended shell for modern applications to use.
In the future, adding new shell protocols support will be easier, as
limited to libweston-desktop.

The library versioning is the same as libweston. If one of them break
ABI compatibility, the other will too.

The compositor will only ever see toplevel surfaces (“windows”), with
all the other being internal implementation details.
Thus, popups and associated grabs are handled entirely in
libweston-desktop.
Xwayland special surfaces (override-redirect) are special-cased to a
dedicated layer, as the compositor should not know about them.

All the shell error checking is taken care of too, as well as some
specification rules (e.g. sizes constraint for maximized and fullscreen
surfaces).

All the compositor has to do is define a few callbacks in the interface
struct, and manage toplevel surfaces.

e54038497d compositor: Mark all views as dirty when a new output is assigned
When all outputs are gone and views were created before they
were gone, such views would have no output object assigned and
nothing would assign it later. This makes sure all views are
set as dirty, so they can get an output assigned when an
output gets plugged in, if they didn't have any output assigned.

This change also works when a new output is added even if there already
are outputs in use. A view may be partly off-screen. If the new output
appears at a position where it overlaps an existing view, that view
should get updated.

It is enough to process only the main view_list, because views not on
that list are not shown for the moment and so do not need an immediate
update. Instead, they will get updated later as needed because making an
off-list view to go on-list inherently requires calling
weston_view_geometry_dirty().

In this patch, only the locking part is fully implemented as in
specified in the protocol, while confinement is only implemented for
when the union of the passed region and the input region of the confined
surface is a single rectangle.

Note that the pointer constraints protocol is still unstable and as
such has the unstable protocol naming conventions applied.

375759e636 Require base-10 for strtol() calls
The third arg to strtol() specifies the base to assume for the number.
When 0 is passed, as is currently done in option-parser.c, hexadecimal
and octal numbers are permitted and automatically detected and
converted.

This change is an expansion of f6051cbab8
to cover the remaining strtol() calls in Weston, where the routine is
being used to read fds and pids - which are always expressed in base-10.
It also changes the calls in config-parser, used by
weston_config_section_get_int(), which in turn is being used to read
scales, sizes, times, rates, and delays; these are all expressed in
base-10 numbers only.

The benefit of limiting this to base-10 is to eliminate surprises when
parsing numbers from the command line.  Also, by making the code
consistent with other usages of strtol, it may make it possible to
factor out the common code in the future.

bac72b29f8 rdp: Check for non-numeric value in RDP_FD env var
strtoul(nptr, endptr, ...) will set *endptr to nptr in the case of where
no digits were read from the string, and return 0.  Running with
RDP_FD=foo would thus result in fd=0 being specified to
freerdp_peer_new(), which is unlikely to be the user's intent.

f8486c33b4 compositor: Untangle surface/view is_mapped from output assignments
Currently, weston assumes a surface/view is mapped if
it has an output assigned. In a zero outputs scenario,
this isn't really desirable.

This patch introduces a new flag to weston_surface and
weston_view, which has to be set manually to indicate
that a surface/view is mapped.

v2:

- Remove usage of new flags from
  weston_{view,surface}_is_mapped at this point. They
  will be added after all the implicit mappings have
  been introduced
- Unmap a surface before unmapping a view so the input
  foci is cleaned up properly
- Remove implicit view mapping from view_list_add
- Cosmetic fixes

v3:

- Rebased to apply on git master

9c764df043 xwayland: make the plugin usable by libweston compositors
This patch follows a similar approach taken to detach the backends from
weston. But instead of passing a configuration struct when loading the
plugin, we use the plugin API registry to register an API, and to get it
in the compositor side.  This API allows to spawn the Xwayland process
in the compositor side, and to deal with signal handling.  A new
function is added in compositor.c to load and init the xwayland.so
plugin.

Also make sure to re-arm the SIGUSR1 when the X server quits.

827b5d225d compositor: add plugin-registry
Implement a simple register and lookup for function tables. This is
intended for plugins to expose APIs to other plugins.

It has been very hard to arrange a plugin to be able to call into
another plugin without modifying Weston core to explicitly support each
case. This patch fixes that.

The tests all pass.

260c2ffd97 input: Rename weston_surface_activate to weston_seat_set_keyboard_focus
The name suggests that it activates surfaces, but the code says it
rather just assigns keyboard focus.  Rename it for clarity, and so the
original function name could be used for something more appropriate
later.  Switch order of parameters since keyboard focus is a property of
the seat.  Update all callers as appropriate.

Change was asked for by pq, May 26, 2016:

 "This should be called weston_seat_set_keyboard_focus(seat, surface).
 Keyboard focus is a property of the seat."

28d240f281 gl-renderer: Always setup gl-renderer
Currently, the gl-renderer setup is being done on per-output
basis. This isn't desirable when trying to make weston run
with zero outputs.

When there are no outputs present, there is no surface available
to attach an EGLContext to with eglMakeCurrent, which makes
any EGL command fail.

The problem is solved by using EGL_KHR_surfaceless_context to
bind an EGLContext to EGL_NO_SURFACE, or if that is
unavailable, creating a dummy PbufferSurface and binding an
EGLContext to it, so EGL gets set up properly.

v2:

- Move PbufferSurface creation into its own function
- Introduce a new EGLConfig with EGL_PBUFFER_BIT set
  and use it to create a PbufferSurface
- Make PbufferSurface attributes definition static
- Check for return of gl_renderer_setup and terminate
  in case it fails
- Remove redundant gl_renderer_setup call from
  gl_renderer_output_create
- Only destroy the dummy surface if it is valid

This patch causes a warning from Mesa when using the i965 driver:
libEGL warning: FIXME: egl/x11 doesn't support front buffer rendering.
A bug has been filed about it since it seems to be spurious:

d84deeb173 compositor-headless: Support starting with zero outputs
This patch adds a new command line option which can be

virtual outputs.

This will be used for output hotplug emulation, where
weston will start with no outputs available, and the
virtual output will be created at runtime.

v2:

- Use bool instead of int for the indicator flag
- Move final newspace to a separate line in command
  line options
