Make sure that we always have the exact same view of the keyboard state
as the host server by using XKB StateNotify events to update our state
exactly rather than relying on key events. In particular, this fixes
key state during grabs, where we either miss modifiers completely or get
them stuck permanently, depending on the nature of the grab and the
implementation of the X window manager/compositor.
The downside, however, is that Weston wakes up on every modifier change,
regardless of whether or not it has focus.

notify_modifiers will now synchronise Weston's internal state with the
XKB state, and send a modifier event if necessary. This eliminates the
need for update_modifier_state to have a return value at all.

If update_state is true, then notify_key will continue to call
xkb_key_update_state to update the local state mask, as before this
commit. Otherwise, it will rely on the compositor to manually update
the state itself, for nested compositors.

If we have XCB XKB support, use XKB's detectable autorepeat, which
generates repeat sequences as a series of
press-press-press-[...]-release events, rather than
press-release-press-release-[...].

X11 has a set of eight modifiers which we want to represent. Cache
their indices when we create a weston_xkb_info, so we can use this from
compositor-x11 to keep the state synchronised exactly between the host X
server and a nested Weston instance.

This is mainly for X11's benefit; the common case is using Logo+S to
take a screenshot, where GNOME Shell has grabbed Logo, and replays the
event down to the nested compositor after S is pressed. This means we
get an enter event with both Logo and S down, and even if Shell delivers
the key press event for S (which isn't mandatory, and not all window
managers do), then we never run the binding since notify_key realises
that S is already down and exits early.

When the focus changes, wl_keyboard_set_focus (and, as an added bonus,
wl_pointer_set_focus) will now send wl_keyboard::modifier events for us
if we store the modifier state in the right place, so we don't have to
worry about that anymore.

It seems we used to rely on the repaint scheduled by the cursor motion.
But if there's no cursor, there's no cursor motion, so we need to schedule
our own repaint.

Since we now batch up damage and only handle it at repaint time, we need
to apply it in case a buffer is destroyed so we don't lose it.
Ander found the problem, but we need to fix it in the compositor so we
don't change the behavior of the compositor.
weston_surface_update_transform() is typically called as part of the
repaint cycle so don't schedule a repaint here. There are still a couple
of places where we call weston_surface_update_transform() manually, but
they don't rely on the repaint being scheduled.
We need to initialize prev when we handle the initial pixel in a
rectangle, or we may detect the following pixel as identical or different
when it's not. This causes the top-left pixel in a rectangle to
occasionally be wrong leaving a trail of "dirty pixels" in the capture.
This is the point where we have just finished rendering the new scene
but before we swap it to the front buffer. At this point, the
output->previous_damage region exactly corresponds to what was just
renders, as compared to previous frame.
We start tracking which hardware plane a surface is displayed on, which
lets us avoid generating damage when a hardware overlay/cursor is moved
around.
EGLDisplay is helpfully typedeffed as void *, which means that you won't
get conflicting-pointer-type warnings if you accidentally confuse it
with weston_compositor::wl_display. Rename it to make it more clear
which display you're dealing with, and also rename compositor-wayland's
parent.display member to parent.wl_display.

We transform the surface damage to global damage at weston_output_repaint()
time. This way we don't touch the transform when it might not be valid
and in case of overlapping damage, we only copy pixels once for shm textures.
Expecting the link to be initialized breaks when compositor-drm.c
takes surfaces out of the list. We could fix that to also
wl_list_init() the link, but we're moving to making the surface list
local to weston_output_repaint(), rebuilt in and only valid during
weston_output_repaint() so just don't touch it instead.
If a surface is map'd and unmap'd before an output repaint occurs, it
is not added to the compositor's surface list, so the field
weston_surface::link might be invalid (the field is initialized on
weston_surface_create()), and it that case Weston will crash on the
call to wl_list_remove(&surface->link) in weston_surface_unmap().
Initialize the surface->link after the call to wl_list_remove() to make
sure a following call to wl_list_remove() won't cause a crash.
Iterate the frame_counter before calling animation->frame() because the animation might be
destroyed in this path. The first frame is now 1 (not 0) in the animation frame handlers.
