191c453f83 meson: link cms-colord with glib and gobject
cms-colord.c calls things like g_string_free() and g_object_unref(), so it
needs to link glib-2.0 and gobject-2.0 explicitly, instead of relying on colord
pkg-config bringing them in.

483c6d4d06 meson: fix building screen-share module
When building screen-share module with meson loading the module
fails with:
  [00:01:28.604] Failed to load module: /usr/local/lib/weston/screen-share.so: undefined symbol: os_create_anonymous_file
  Failed to process Wayland connection: Broken pipe
  failed to create display: Broken pipe

The function os_create_anonymous_file is defined in libshared,
adding libshared to the dependency makes sure the function gets
compiled into screen-share.so.

6e229ca263 weston: add more libinput config options
This is so that, for instance, people using weston as their main Wayland
compositor can invert the sense of two finger scrolling or change
pointer acceleration using weston.ini, rather than having to edit C
code.

All of the options that libinput itself exposes through its API are now
exposed in weston.ini.  The new options are called `tap-and-drag`,
`tap-and-drag-lock`, `disable-while-typing`, `middle-emulation`,
`left-handed`, `rotation`, `accel-profile`, `accel-speed`,
`scroll-method`, `natural-scroll`, and `scroll-button`. I have
successfully tested everything except for `rotation`, out of a lack of
hardware support.

weston now depends directly on libevdev for turning button name strings into
kernel input codes. This was needed for the `scroll-button` config
option. (weston already depends indirectly on libevdev through
libinput, so I figured people would be OK with this.) As a practical
matter for debian-style packagers, weston now has a build dependency on
libevdev-dev.

Right now, the code applies the same options to all attached devices
that a given option is relevant for. There are plans for multiple
[libinput] sections, each with different device filters, for users who
need more control here.

22dd67ccea weston: Add config option to enable pixman-based rendering

4e1d9bc72f libweston: Allow taking screenshots when debug protocol is enabled
Screenshots of the outputs can only be taken by having a keyboard
plug-ed in, as to avoid potential malicious intent. On the other hand,
this is problematic as there are cases where a keyboard cannot
be used as a input device. A particular use-case is that for
multiple devices it can be cumbersome to connect a keyboard such
that using ssh can be much easier and can be further automated.

This patch allows taking screenshots without the need of having a
keyboard connected when debug protocol is enabled.

Add also a few words about the fact that this is a serious issue
and can lead to silently leaking the output contents.

8011b0fa03 Add Meson build system
Meson is a build system, currently implemented in Python, with multiple
output backends, including Ninja and Make. The build file syntax is
clean and easy to read unlike autotools. In practise, configuring and
building with Meson and Ninja has been observed to be much faster than
with autotools. Also cross-building support is excellent.

More information at http://mesonbuild.com

Since moving to Meson requires some changes from users in any case, we
took this opportunity to revamp build options. Most of the build options
still exist, some have changed names or more, and a few have been
dropped. The option to choose the Cairo flavour is not implemented since
for the longest time the Cairo image backend has been the only
recommended one.

This Meson build should be fully functional and it installs everything
an all-enabled autotools build does. Installed pkg-config files have
some minor differences that should be insignificant. Building of some
developer documentation that was never installed with autotools is
missing.

It is expected that the autotools build system will be removed soon
after the next Weston release.

d3630ed489 compositor: offer logs via weston-debug
This registers a new weston-debug scope "log" through which one can get

Anywhere where the varargs set is used twice (once for vfprintf, another
for the debug scope), we copy the va_list in order to avoid reusing it,
which leads to memory safety issues.

944dd235b4 weston: support clone mode on DRM-frontend
Add a new output section key "same-as" for configuring clone mode. An
output marked "same-as" another output will be configured identically to
the other output.

The current implementation supports only CRTC sharing for clone mode.
Independent CRTC clone mode cannot be supported until output layout
logic is moved from libweston into the frontend and libweston's damage
tracking issues stemming from overlapping outputs are solved.

Quite a lot of infrastructure is needed to properly configure clone
mode. The implemented logic allows easy addition of independent CRTC
clone mode once libweston supports it. The idea is that wet_layoutput is
the item to be laid out and all weston_outputs a wet_layoutput
contains show exactly the same area of the desktop.

The configuration logic attempts to automatically fall back to creating
more weston_outputs when all heads do not work under the same
weston_output. For now, the fallback path ends with an error message.

Enabling a weston_output is bit complicated, because one needs to first
collect all relevant heads, try to attach them all to the weston_output,
and then back up head by head until enabling the weston_output succeeds.
A new weston_output is created for the left-over heads and the process
is repeated.

CRTC-sharing clone mode is the most efficient clone mode, offering
synchronized scanout timings, but it is not always supported by
hardware.

v10:
- rebased trivial conflicts in man page
- switch to gitlab issue URL

v9:
- replace weston_compositor_set_heads_changed_cb() with
  weston_compositor_add_heads_changed_listener()
- remove workaround in simple_head_enable()

v6:
- Add man-page note about cms-colord.
- Don't create an output just to turn it off.

The signal has been replaced with the heads_changed hook and is no
longer useful.

weston_pending_output_coldplug() is renamed to
weston_compositor_flush_heads_changed() for two reasons: it better
describes what it does now, and it serves as an obvious flag that
libweston ABI has been broken.

e868c3fc15 libweston: change windowed_output_api output_create to create_head
Rename the function pointer to create_head() because that is what it
does on backends that are converted to the head-based API. Update the
documentation to match.

Surprisingly this is not an ABI break, as the function behaviour and
signature remain intact. Hence API_NAME is not bumped.

This is only an API break, and main.c is fixed accordingly.

1394ac303e weston: migrate DRM to head-based output API
Migrate the DRM frontend to use the simple head-based output
configurator, maintaining the exact same features and semantics as
before.

This is an intermediate step. It is unoptimal to create a weston_output
just to turn it off, but the libweston implementation and the DRM
backend require it for now. In the future, the DRM frontend will get its
own configurator that does not create useless weston_outputs and
supports clone mode by attaching multiple heads to the same
weston_output. Clone mode is not yet supported by libweston/DRM.

Until we remove the need to create a weston_output just to turn it
"off", that is, disable it, we will hit simple_head_enable() for heads
we have already disabled. As long as the DRM-backend conversion to the
head-based API is not complete, attempting to create an output for a
head again would lead to a crash. This problem does not exist right now,
but it will after the patch "compositor-drm: start migration to
head-based output API". Therefore, check if the head we are about to
process is already attached, and do nothing if so. DRM outputs set to
"off" are the only ones legitimately hitting this condition.

This is the last frontend migrated, wet_set_pending_output_handler() is
deleted as dead code.

v9:
- Add the workaround in simple_head_enable().

cd8a1a8182 weston: migrate headless to head-based output API
Migrate the headless frontend to use the new head-based output
configuration API: listen for heads_changed, and process all heads.

The simple_heads_changed() function is written to be able to cater for
all backends. The rest will be migrated individually.

The head destroy listeners are not exactly necessary, for headless
anyway, but this is an example excercising the API. Also
is_device_changed() check is mostly useful with DRM.

v8:
- replace weston_compositor_set_heads_changed_cb() with
  weston_compositor_add_heads_changed_listener()
- fix comment on wet_head_tracker_create()

v3: Print "Detected a monitor change" only for enabled heads.

cf0a476b8e cms-colord: find a good head
The 'head' member of 'struct weston_output' is going to go unused and
then disappear, so stop using it and find a head from the proper list.

However, this leaves a problem in cms-colord: if you have multiple
monitors driver with the same CRTC, what do you say to the color
management system? The monitors could be different, but all the color
LUTs etc. are in the CRTC and are shared, as is the framebuffer.

Do the simple hack here and just use whatever head happens to be the
first in the list.

The warning is printed in get_output_id(), because if heads are added or
removed while the output is enabled, the id could change.

v6:
- add weston_output_get_first_head(), at first use
- add warning message for nr. heads > 1
