output_id_pool is defined as a uint32_t, thus ffs() provides a range of
1-32 available id numbers. When the 33rd output is enabled, Weston will
set the ID to (unsigned)(-1) and thus lead to some unexpected
behaviors.
I'm not sure what the best way to handle this error would be since this
is in an initialization routine, but at least let's document the
potential error condition with an assert().

Valgrind has shown that in at least one place (default_grab_pointer_focus)
we're testing uninitialized values coming out of weston_compositor_pick_view.
This is happening when default_grab_pointer_focus is called when there is
nothing on the view list, and during the first repaint when only the black
surface with no input region exists.
This patch adds a function to clear pointer focus and also set the sx,sy
co-ordinates to a sentinel value we shouldn't compute with.
Assertions are added to make sure any time pointer focus is set to NULL
these values are used.
weston_compositor_pick_view() now returns these values too.
Now the values are always initialized, even when no view exists, and
they're initialized in such a way that actually doing computation
with them should fail in an obvious way, but we can compare them

If a stopped repaint loop gets restarted due to posting of new
damage, and this restart of the repaint loop happens late in the
video refresh cycle, ie. already inside the repaint-window and
thereby after the composition deadline for the current frame,
then defer the actual output repaint to the composition deadline
of the next video refresh cycle by setting the repaint timer
accordingly.
This tries to make sure that:
a) Client(s) posting damage timely before the composition deadline
(video refresh duration - "repaint-window" duration) of the
current refresh cycle will trigger a repaint within the current
refresh cycle, thereby avoiding one extra frame of compositor
lag due to the needed restart of the repaint loop if the loop
was stopped. This allows them to benefit from the earlier
"instant repaint restart" commit to keep latency low.
b) Late clients which post damage close to the end of a refresh
cycle can't race other clients if the repaint loop is restarted.
Instead they will get deferred to the next compositor cycle,
just as if the repaint loop would have been already running -
the semantic of the "repaint-window" parameter is preserved.
This is especially important to prevent a very late client
from triggering a repaint very close to the vblank, which
would cause the compositor to certainly miss the vblank and
skip one frame and then cause a delay of another frame for
other clients which posted their damage in time for the
following frame. Iow. this provides clients with a more
predictable compositor timing and makes it easier for them
to latch onto the compositors repaint cycle.

The compositor's output_created signal used to be sent in weston_output_init()
which the backend call before putting the output in the output_list.
This caused problems when creating a new view in a listener to that signal,

To fix this add a new weston_composito_add_output() func which adds the
output in the list and later sends the signal, and make the backends call
that.
The other set_focus() functions take the relevant type instead of a seat
already, so this is consistent.

Clients will load the config file pointed to by WESTON_CONFIG_FILE. If
the environment variable is set but empty, no config file will be
loaded. If the variable is unset, things fall back to the default
"weston.ini".
Note, that Weston will only set WESTON_CONFIG_FILE, it never reads it.

This timer delays the output_repaint towards the end of the refresh
period, reducing the time from repaint to present.
The length of the repaint window can be set in weston.ini.
The call to weston_output_schedule_repaint_reset() is delayed by one
more period. If we exit the continuous repaint loop (set
output->repaint_scheduled to false) in finish_frame, we may call
start_repaint_loop() unnecessarily. The problem case was actually
observed with two outputs on the DRM backend at 60 Hz, and 7 ms
repaint-window. During a window move, one output was constantly falling
off the continuous repaint loop and introducing additional one frame
latency, leading to jerky window motion. This code now avoids the
problem.
Changes in v2:
- Rename repaint_delay_timer to repaint_timer and
output_repaint_delay_handler to output_repaint_timer_handler.
- When computing the delay, take the current time into account. The timer
uses a relative timeout, so we have to subtract any time already gone.
Note, that 'gone' may also be negative. DRM has a habit of predicting
the page flip timestamp so it may be still in the future when we get the
completion event.
- Do also a sanity check 'msec > 1000'. In the unlikely case that
something fails to provide a good timestamp, never delay for more than
one second.
