Besides the fact of the frame not being done, assigning planes before
the vblank handler is called will make the state inconsistent, leading
to a crash.
Check if the output passed to drm_output_prepare_overlay_surface() does
actually contain the surface and fail if it doesn't. Also fail if a
surface spans multiple outputs since clearing the damage will cause the
portion that is not in an overlay to not be updated at all.
This way, if initialisation fails (say, udev or Mesa are broken, or we
couldn't find any devices), we'll at least take you back to where you
were, rather than leave you at a totally broken VT you can't escape
from.

weston_compositor_init is always called late because most
implementations can't initialise GL until fairly late in the game.
Split it into a base version with the same name, followed by
weston_compositor_init_gl which can be called later on.
This simplifies compositor-wayland, which no longer needs a separate
global handler just for wl_seat.

We start tracking which hardware plane a surface is displayed on, which
lets us avoid generating damage when a hardware overlay/cursor is moved
around.
EGLDisplay is helpfully typedeffed as void *, which means that you won't
get conflicting-pointer-type warnings if you accidentally confuse it
with weston_compositor::wl_display. Rename it to make it more clear
which display you're dealing with, and also rename compositor-wayland's
parent.display member to parent.wl_display.

wl_input_device has been both renamed and split. wl_seat is now a
virtual object representing a group of logically related input devices
with related focus.
It now only generates one event: to let clients know that it has new
capabilities. It takes requests which hand back objects for the
wl_pointer, wl_keyboard and wl_touch interfaces it exposes which all
provide the old input interface, just under different names.
This commit tracks these changes in weston and the clients, as well as
similar renames (e.g. weston_input_device -> weston_seat). Some other
changes were necessary, e.g. renaming the name for the visible mouse
sprite from 'pointer' to 'cursor' so as to not conflict.
For simplicity, every seat is always exposed with all three interfaces,
although this will change as time goes on.

Currently, the drm backend will create and destroy a KMS FB for each
frame. However, the bos for a gbm surface are reused (at least with
mesa) so we can store the fb_id on it and destroy it only on the bo's
destroy callback.
To use the same path for scanning out client buffers, some refactor
was needed. Previously, the bo for the client buffer was destroyed
early so that gbm_surface_release_buffer() would not be called with
it, since at the page flip handler output->scanout_buffer can be
NULL even if the current frame is a client buffer.
This was solved by adding a drm_fb structure that holds a gbm_bo,
an fb_id, and information about the fb coming from a client buffer
or not. A drm_fb is created in such a way that it is destroyed
whenever the bo it references is destroyed. The fields current_*
and next_* in drm_output are changed into only two pointers to
drm_fb's.
Switching display mode may happen when:
1. The fullscreen surface is at top most in fullscreen layer and with
"driver" method. Shell will switch output mode to match the surface
size. If no matched mode found, fall back to "fill" method.
2. The top fullscreen surface is destroyed or unset. Switch back to the
origin mode.
Some GL implementations do not provide GL_EXT_read_format_bgra
extension.
Set a glReadPixels format based on whether the extensions is supported
or not, and use that format in all backends.
Add RGBA->BGRA swapping copy to screenshooter to keep the shm buffer
data format as BGRA.

Removing the input devices will trigger events and activity that will cause
a redraw. Do this before we put the compositor to sleep so we can cancel it
properly and avoid immediately waking the compositor again.
We dont want to receive hotplug events while being inactive.
When getting back active we enumerate all devices and would end up
with two sources for one device that may be hotplugged in the mean time.
weston-launch starts weston and provides mechanism
for weston to set/drop drm master, open a tty,
and read input devices without being root.
Execution is allowed for local-active sessions
or users in the group weston-launch.
The remaining use case was making our context current before we had any
output surfaces. We can do that now using a dummy surface, so let's stop
relying on surfaceless.
Instead of using the hacks of gbm_bos, EGLImage, FBOs and surfaceless
we switch to using the new gbm surface API. This gives us an EGL
native window type for gbm and lets us use a real EGL surface.
On one hand, getopt (in particular the -o suboption syntax) sucks on the
server side, and on the client side we would like to avoid the glib
dependency. We can roll out own option parser and solve both problems
and save a few lines of code total.
Udev provides a convenient helper. Use it instead of working with the
property-list directly.

If we have multiple video devices on the system (card0, card1), we should
ignore hotplug events for cards that we do not use. This avoids calling
update_outputs() if the event was not generated by our device so we avoid
refreshing the DRM information if it didn't change.

When creating outputs in the drm compositor, if allocating crtcs
fails, then free the drm resources. Also, if the base output list is
empty, free drm resources
DPMS kicks in only when wscreensaver is launched, in the moment that shell
call lock() for the second time. Backlight control internals are managed by
