Rather than magically trying to infer what the buffer is and what we
should do with it when we go to destroy it, add an explicit type
instead.
In doing so, the test for dumb images (destroying them, but only if
they're not the 'live' ones) is removed. This was dead code, as the only
path which could cause us to shuffle images is drm_output_switch_mode.
This calls drm_output_release_fb before the images are reallocated in
drm_output_fini_pixman / drm_output_init_pixman, with the reallocation
unconditionally destroying the images, so can never be hit.

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.

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().

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.

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.

- 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
