Normally we need to check if a seat's [device_type]_count is > 0 before
we can use the associated pointer. However, in a binding you're
guaranteed that the seat has a device of that type. If we pass in
that type instead of the seat, it's obvious we don't have to test it.
The bindings can still get the seat pointer via whatever->seat if they
need it.
This is preparation for a follow up patch that prevents direct access
to seat->device_type pointers, and this will save us a few tests at
that point.

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.

drm_output_start_repaint_loop() incurred a delay of
one refresh cycle by using a no-op page-flip to get
an accurate vblank timestamp as reference. This causes
unwanted lag whenever Weston exited its repaint loop, e.g.,
whenever an application wants to repaint with less than
full video refresh rate but still minimum lag.
Try to use the drmWaitVblank ioctl to get a proper
timestamp instantaneously without lag. If that does
not work, fall back to the old method of idle page-flip.
This optimization will work on any drm/kms driver
which supports high precision vblank timestamping.
As of Linux 4.0 these would be intel, radeon and
nouveau on all their supported gpu's.
On kms drivers without instant high precision timestamping
support, the kernel is supposed to return a timestamp
of zero when calling drmWaitVblank() to query the current
vblank count and time iff vblank irqs are currently
disabled, because the only way to get a valid timestamp
on such kms drivers is to enable vblank interrupts and
then wait a bit for the next vblank irq to take a new valid
timestamp. The caller is supposed to poll until at next
vblank irq it gets a valid non-zero timestamp if it needs
a timestamp.
This zero-timestamp signalling works up to Linux 3.17, but
got broken due to a regression in Linux 3.18 and later. On
Linux 3.18+ with kms drivers that don't have high precision
timestamping, the kernel erroneously returns a stale timestamp
from an earlier vblank, ie. the vblank count and timestamp are
mismatched. A patch is under way to fix this, but to deal with
broken kernels, we also check non-zero timestamps if they are
more than one refresh duration in the past, as this indicates
a stale/invalid timestamp, so we need to take the page-flip
fallback for restarting the repaint loop.
v2: Implement review suggestions by Pekka Paalanen, especially
extend the commit message to describe when and why the
instant restart won't work due to missing Linux kernel
functionality or a Linux kernel regression.

Looking at the first of these, unbind_input_panel() gets called when the
text-backend destroys its helper client which has bound to input_panel
interface. This happens after the shell's destroy_signal callback has
been called, so the shell has already been freed.
The other two errors come from
wl_list_remove(&input_panel_surface->link);
which has gone stale when the shell was destroyed
(shell->input_panel.surfaces list).
Rather than creating even more destroy listeners and hooking them up in
spaghetti, modify text-backend to not hook up to the compositor destroy
signal. Instead, make it the text_backend_init() callers' responsibility
to also call text_backend_destroy() appropriately, before the shell goes
away.
This fixed all the above Valgrind errors, and avoid a crash with
ivi-shell when exiting Weston.
Also using desktop-shell exhibited similar Valgrind errors which are
fixed by this patch, but those didn't happen to cause any crashes AFAIK.
