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.

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.

58f98c99f5 Move weston source to compositor/
This is the start of separating weston-the-compositor source files from
libweston source files.

This is moving all the files related to the 'weston' binary. Also the
CMS and systemd plugins are moved.

xwayland plugin is not moved, because it will be turned into a
libweston feature.

To avoid breaking the build, #includes for weston.h are fixed to use
compositor/weston.h. This serves as a reminder that such files may need
further attention: moving to the right directory, or maybe using the
proper -I flags instead.

v2: Move also screen-share.c, and add a note about weston-launch.

4e18448286 xwm: Don't clear the selection if it has no text type available
weston maintains a copy of the most recently selected "thing" - it picks
the first available type when it copies, and saves that one only.

When an application quits weston will make the saved selection active.

When xwm sees the selection set it will check if any of the offered types
are text.  If no text type is offered it will clear the selection.

weston then interprets this in the same way as an application exiting and
causing the selection to be unset, and we get caught in a live lock with
both weston and xwayland consuming as much cpu as they can.

The simple fix is to just remove the test for text presence.

f05d18f3ee xwm: let the shells decide the position of X windows
The xwm used to automatically send to Xwayland the position of X windows
when that changed, using the x,y of the primary view of the surface.
This works fine for the desktop shell but less so for others.
This patch adds a 'send_position' vfunc to the weston_shell_client that
the shell will call when it wants to let Xwayland know what the position
of a window is.
The logic used by the desktop-shell for that is exactly the same the xwm
used to have.

aa9747833e xwm: use always a valid 'primary view' for an X window
The xwm gets a primary view for a X window using the get_primary_view
vfunc of the shell_interface struct. Storing it is dangerous though
because it doesn't listen for its destruction so it may end up using the
old stored view pointer after that view was freed, or after the primary
view for that window was changed to another one.

Fetch the primary view just before using it every time and try to not
abuse this 'primary view' concept which may map badly to some shells:
iterate over all the views instead when it makes sense.

9a0b2b54e2 xwm: Fix a weston crash when a window surface is created after unmap

This patch removes the window from the unpaired list during unmap, so we
should never get to the destroy handler with a surface destroy listener set.

surface destroy listener in the destory handler.

50b6747903 compositor: send error for surface role resets
With the more accurate definition of wl_surface roles in Wayland,
enforce the restriction: a role is always set permanently, and
attempting to change it is a protocol error.

This patch is based on Jasper's patch:
http://lists.freedesktop.org/archives/wayland-devel/2014-August/016811.html

The difference in this patch compared to his are:

- send role errors on the interface whose request triggers it, not on
  wl_surface

- an interface could have several requests assigning different roles,
  cannot use wl_interface as the unique key; use an arbitary string
  instead

- ensure in window-manager.c that create_shell_surface() ->
  create_common_surface() is never called with surface->configure set,
  to avoid compositor abort

- use wl_resource_post_no_memory() where appropriate instead of
  hand-rolling it with wl_resource_post_error()

Ideally we would not add weston_surface::role_name field, but use
weston_surface::configure. At the moment this is not possible though,
because at least shell.c uses several different roles with the same
configure function. Drag'n'drop uses two configure functions for the
same role. The configure hook is also reset in several places,
which is not good for role tracking.

This patch overlooks the wl_surface roles assigned in privileged
extensions: screensaver, panel, background, lock, input panel.

3c6d20c5eb xwm: Check whether the seat is NULL when needed in weston_wm_handle_button
XCB and wayland input event handling exists together in xwm, which can
cause problems. weston_wm_handle_button is called via XCB events, while
it calls weston_wm_pick_seat_for_window, which uses info from compositor
(pure wayland). It is also true in setting and removing flags of frames.
Races can happen in between, when resize of moving flag of the frame is
still set while the button has been released, the picked seat will be
NULL in weston_wm_handle_button, causing crash. We can safely ignore
moving or resizing if this happens. The same applies to c06a180d.

8ffd38bedb wm: Don't subtract the margins from the configured size
When we moved the configure event size to being based on the window
geometry, we changed the coordinates of the configure request to being
frame geometry based. Frame geometry includes titlebar and border, but
not shadow margins.

434cc23426 xwayland: Clean up the WM properly if X server crashes
The X cleanup code uses wxs->wm to check if the WM has been created - but that
variable was never initialized. So if X crashes, the WM doesn't get destroyed,
causing a crash when it tries to repaint a window.

c06a180dd5 xwm: check whether the picked seat can be NULL
The seat picked in weston_wm_window_handle_moveresize can sometimes
be NULL when it is (somehow) triggered with all buttons released.

This patch checks whether the seat is NULL to avoid NULL dereference.

0250a740c2 xwayland: Better handle a race with X
If X windows are created and destroyed very fast sometimes the WM window
object gets created and destroyed before we get around to handling client
messages.  Failing to check that the window is still valid can result in a
segfault.

cf4c13af98 xwayland: set surface_id to 0 when client resource is found
When Xwayland requests that a wl_surface be created and the X event is
handled before the wayland requests, a surface ID is stored to
window->surface_id and the window is added to the unpaired window list. When
weston_wm_create_surface is called, the window is removed from the list and
window->surface_id is set to zero. If window->surface_id is not zero when
weston_wm_window_destroy is called, the window is assumed to be in the
unpaired window list and wl_list_remove is called. If
weston_wm_window_handle_surface_id is called and the surface has already
been created, the window is not added to the unpaired window list, but
window->surface_id isn't set to zero. When the window is destroyed, removing
the window from the list is attempted anyway and a crash occurs.

This patch stores the surface ID in a temporary variable and only assigns it
to window->surface_id when the window is added to the unpaired window list.
Otherwise window->surface_id is set to zero to maintain its use as a flag
variable.

ccf48fb4f9 shell: Replace set_margin with set_window_geometry
Currently, there is a fun flicker when toggling maximization or
fullscreen on a window in mutter or more sophisicated compositors
and WMs.

What happens is that the client want so go maximized, so we
calculate the size that we want the window to resize to (640x480),
and then add on its margins to find the buffer size (+10 = 660x500),
and then send out a configure event for that size. The client
renders to that size, realizes that it's maximized, and then
says "oh hey, my margins are actually 0 now!", and so the compositor
has to send out another configure event.

In order to fix this, make the the configure request correspond to
the window geometry we'd like the window to be at. At the same time,
replace set_margin with set_window_geometry, where we specify a rect
rather than a border around the window.

ac985be8ce compositor: Remove the edges parameter from send_configure
send_configure was originally modelled after
wl_shell_surface::send_configure, which takes these arguments. However,
the X WM and xdg_surface::configure variants don't use these arguments.

We already store the resize edges for a surface while it's being
resized, so just use the saved state in the wl_shell_surface variant.

8c3c738718 xwayland: Handle race between multi-pointer motion and clicks
Make sure we're looking at the right location.  The frame could have
received a motion event from a pointer from a different wl_seat, but
under X it looks like our core pointer moved.  Move the frame pointer
to the button press location before deciding what to do.

052ef4e7bc xwayland: Be smarter about picking seats for move/resize
If we're going to move or resize an xwayland surface, we used to just
pick the first seat in the list for doing the move/resize.  Ideally we
can map from the XInput device doing the click to the corresponding
weston_seat, but that requires using xcb xinput, which isn't well supported.

Instead, lets use a simple heuristic that just picks the pointer that
most recently delivered a button event to the window in question.
