comment that falling through is OK. Insert some to make it happy.

05df8c16ec Change boolean repaint_scheduled to quad-state enum
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.

3615ce1955 Don't delay initial output paint
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.

84aff5c77a Calculate next-frame target time in absolute space
Rather than determining the time until next-frame repaint in relative
space (time until repaint), determine it first in absolute space, and
then later convert this to relative.

This will later allow us to store these per-output, so we can have a
single idle timer which will allow us to aggregate multiple repaints
together when timing allows.

11ae2a3036 compositor-drm: pageflip timeout implementation
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().

75487c2560 compositor-drm: Try to preserve existing output routing
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.

c8890125ad compositor-drm: don't put y-inverted / interlaced / bottom-first dmabufs on overlays
This patch checks the attribute flags on incoming dmabufs and refuses to
put them overlays if they have any of the flags set (currently:
ZWP_LINUX_BUFFER_PARAMS_V1_FLAGS_Y_INVERT,
ZWP_LINUX_BUFFER_PARAMS_V1_FLAGS_INTERLACED and
ZWP_LINUX_BUFFER_PARAMS_V1_FLAGS_BOTTOM_FIRST), instead defaulting to
the gl-renderer which can handle some of the flags.

This check should be superceded by buffer transforms, when they become
available.

27799355a9 ivi-shell: simplify commit_changes function
It is a better idea to use one for loop instead
of using three nested for loops.

We do not need to update the transformation of
views according to the scenegraph. The important
thing is that every visible view is updated before
commit_changes function returns.

The first if statement checks, if the view is on
the currently rendered scenegraph. The second if
statement checks, if the view's layer or surface
is visible. These checks ensure that we do not
update the transformation matrix of a view, which
is not visible on the screen.
