Derek Foreman 22276a596a zoom: Store the seat that initiated a zoom
Track the seat that initiated a seat instead of picking the first one.

Previously, if there are multiple seats then any seat can adjust the zoom
level but the zoom tracks the first seat's pointer.

Now the zoom will follow the pointer of the seat that initiated the zoom.

Additionally, if there's no pointer in the first seat, starting a zoom
with the second seat will no longer crash weston.

Mario Kleiner 7e07db9207 cms-helper/static: Add "identity" builtin cms profile (v3)
Allows to force loading an identity gamma table if
option icc_profile= is given in weston.ini for
an output, ie., icc_profile= is specified to an
empty assignment.

Some special display output devices, e.g., for
neuro-science applications, and special display
testing hardware need a guaranteed perfect pixel
passthrough from framebuffer to output. This is
an easy way to set this up for cms-static.

v2: Remove confusing/redundant weston_log debug output.
v3: Don't use the "identity" keyword to trigger this, but
    instead assignment of an empty string will trigger
    loading of an identity LUT. Suggested by Derek Foreman.

Mario Kleiner 2611ebd316 cms-colord: Fix crash at compositor shutdown. (v2)
cms-colord used the weston_compositor destroy signal to
trigger its final colord_module_destroy cleanup, and the
wl_output destroy signal to trigger per output cleanup.

The problem is that the compositor destroy signal gets
emitted before the output destroy signals at compositor
shutdown, colord_module_destroy would free all its
shared data structures and then later on the output
destroy callback would try to access those shared
data structures when handling output destruction
-> Use after free -> Crash, usually with VT switching
dead and thereby an unuseable system requiring a reboot.

Solve this by moving the output destruction handling into
the colord_cms_output_destroy() cleanup function for
colord-cms own hash dictionary of all active outputs.

The output destroy callback just removes the corresponding
output from the dictionary and triggers proper cleanup if
an output is unplugged during runtime. During compositor
shutdown, the dictionary as a whole is released before
releasing all other shared data structures, thereby
triggering cleanup of all remaining outputs.

Tested to fix crashes on x11 and drm backends.

v2: Formatting: Wrap lines to < 80 characters, as suggested
    by Derek. Thanks.

When a seat is required, we can access through the device we have
and use that to get to other device types for the seat, provided
we validate them appropriately.

Derek Foreman 8ae2db5b0c input: Pass the appropriate pointer type to bindings instead of a seat
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.

Mario Kleiner b7df04ebc0 compositor: Respect repaint-window when restarting repaint loop.
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.

Mario Kleiner f507ec3587 compositor-drm: Allow instant start of repaint loop. (v4)
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.
