Allow global control of the pixman shadow buffers. The compositor can
choose whether all output use or do not use a shadow buffer with the
pixman renderer.
The option is added to the end of struct weston_drm_backend_config to
avoid bumping WESTON_DRM_BACKEND_CONFIG_VERSION.

Developers with testing rigs having multiple graphics cards plugged in
often want to test things on a specific card. We have ways to choose a
card through seat assignments, but configuring that run by run is
awkward.
Add a new DRM backend option to try to open a specific device, and quit
if it fails.

[Pekka: bump WESTON_DRM_BACKEND_CONFIG_VERSION]
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.co.uk>
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().

This is a complete port of the DRM backend that uses
the 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 or obtained from the configuration
file using previously added functionality. It is
required that the scale and transform values are set
using the previously added functionality.
After everything has been set, output needs to be
enabled manually using weston_output_enable().
v2:
- Added missing drmModeFreeCrtc() to drm_output_enable()
cleanup list in case of failure.
- Split drm_backend_disable() into drm_backend_deinit()
to accomodate for changes in the first patch in the
series. Moved restoring original crtc to
drm_output_destroy().
v3:
- Moved origcrtc allocation to drm_output_set_mode().
- Swapped connector_get_current_mode() and
drm_output_add_mode() calls in drm_output_set_mode()
to match current weston.
- Moved crtc_allocator and connector_allocator update
from drm_output_enable() to create_output_for_connector()
to avoid problems when more than one monitor is connected
at startup and crtc allocator wasn't updated before
create_output_for_connector() was called second time,
resulting in one screen being turned off.
- Moved crtc_allocator and connector_allocator update from
drm_output_deinit() to drm_output_destroy(), as it
should not be called on drm_output_disable().
- Use weston_compositor_add_pending_output().
- Bump weston_drm_backend_config version to 2.
v4:
- Reset output->original_crtc to NULL if drm_output_set_mode()
fails.
- Remove unneeded log message when disabling an output when a
pageflip is pending.
- Document that create_output_for_connector() takes ownership
of the connector.
- Free the connector if create output conditionals are not met
in create_outputs() and update_outputs().

Preparing for libweston and for the separation of the code base into
libweston vs. weston the compositor, we must remove all uses
weston_config structures from the backends. We have decided that all
option and config input happens in the compositor (main.c), and
configuration is passed in for the backends as structs.
Most other backends have already converted, and this patch converts the
DRM-backend to the libweston-style init API.
The libweston-style init API includes a header for each backend (here
compositor-drm.h) defining the configuration interface. The compositor
(main.c) prepares a configuration struct to be passed through libweston
core to the backend during initialization.
A complication with the DRM-backend is that outputs can be hotplugged,
and their configuration needs to be fetched from the compositor
(main.c). For this, the config struct contains a callback member. The
output configuration API is subject to change later, this is just a
temporary API to get libweston forward.
As weston_compositor's user_data was not previously used for anything,
and the output configuration callback needs data, the user_data is set
to the 'config' pointer. This pointer is only used in
drm_configure_output() in main.c.
