Remove the unstable presentation_timing.xml file, and use
presentation-time.xml from wayland-protocols instead to generate all the
Presentation extension bindings.
The following renames are done according to the XML changes:
- generated header includes
- enum constants and macros prefixed with WP_
- interface symbol names prefixed with wp_
- protocol API calls prefixed with wp_
Clients use wp_presentation_interface.name rather than hardcoding the
global interface name: presentation-shm, weston-info, presentation-test.

[Pekka: updated wayland-protocols dependency to 1.2]
A new optional parameter "-d msecs" allows to specify a
delay before the surface attach/damage/commit to shift
the point in time when a surface update is committed.
This allows to test how different client timings interact
with the compositors repaint timing.

v2: Clarify the intent, doing a delay in window_create_feedback()
is a bit surprising. Use nanosleep() instead of clock_nanosleep(),
which may not support the chosen presentation clock.

To help reduce code duplication and also 'kitchen-sink' includes
the ARRAY_LENGTH macro was moved to a stand-alone file and
referenced from the sources consuming it. Other macros will be
added in subsequent passes.

This started as a copy of simple-shm.c before it was converted to
xdg_shell.
This demo excercises the presentation feedback interface in five
different modes:
- A continuous repaint loop triggered by frame callbacks, and using
immediate commits, just gathering presentation feedback and computing
some time intervals for statistics.
- The same as above, except with 1s sleep before actually repainting as
a response to frame callback. This tests how well the compositor can
do a repaint from idle state (not continuously repainting), assuming
nothing else is causing repaints.
- A continuous repaint loop triggered by 'presented' events rather than
by frame callbacks. If Weston uses an appropriate scheduling
algorithm, this mode achieves the smallest possible frame latency
(below one output refresh period).
In all modes, all frames are pre-rendered at startup, so no rendering
happens during the animation.
