struct wayland_output::name was used but never initialized.
Also zxdg_toplevel_v6_set_title was only called for windowed outputs,
and some compositors let you see the client's name even when it is
fullscreen (GNOME Shell's Activities menu for example).
So rename struct wayland_output::name to struct wayland_output::title and
precompute it on wayland_output_create_common(), so it can be later used
on xdg's set_title and frame_create.

repaint_scheduled is actually cleverly a quad-state, disguised as a
boolean. There are four possible conditions for the repaint loop to be
in at any time:
- loop idle; no repaint will occur until specifically requested, which
may be never (repaint_scheduled == 0)
- loop schedule to begin: the loop was previously idle, but due to a
repaint-schedule request, we will call the start_repaint_loop hook
in the next idle task
- repaint scheduled: the compositor has definitively scheduled a
repaint request for this output, which will occur in fixed time
- awaiting repaint completion: the backend has not yet signaled
completion of the last repaint request, and the compositor will not
schedule another until it does so
All but the first condition were previously conflated as
repaint_scheduled == 1, but break them out into separate conditions to
aid clarity, backed up by some asserts.

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.
