The global wl_pointer_gestures object is now created, effectively
bridging pinch/swipe gestures with clients, so they're now
accessible to clients implementing the protocol.
Instead of moving around all the bound pointer resources for a client
when changing focus, keep all the resources bound by a client in a per
client struct, and track the focus by having a pointer to the current
active pointer client struct instance.
This will simplify having wl_pointer extensinos sharing the pointer
focus of the wl_pointer by only having to add them to the pointer
client.

While we shouldn't normally receive crossing events for any windows
except the stage when running nested, we do in case we hold a pointer
grab - just ignore those events instead of taking down the user's
session.
The spec says:
"A server should avoid signalling the frame callbacks if the surface is not
visible in any way, e.g. the surface is off-screen, or completely obscured
by other opaque surfaces."
We actually do have the information to do that but we are always calling
the frame callbacks in after_stage_paint. So fix that to only call when
when the surface gets drawn on screen.

The compositor maintains a ring of shared fences with the X server in order to
properly synchronize rendering between the X server and the compositor's GPU
channel. When all of the fences have been used, the compositor needs to reset
one so that it can be reused. It does this by first waiting on the CPU for the
fence to become triggered, and then sending a request to the X server to reset
the fence.
If the compositor's GPU channel is busy processing other work (e.g. the desktop
switcher animation), then the X server may process the reset request before the
GPU has consumed the fence. This causes the GPU channel to hang.
Fix the problem by having the compositor's GPU channel trigger its own fence
after waiting for the X server's fence. Wait for that fence on the CPU before
sending the reset request to the X server. This ensures that the GPU has
consumed the X11 fence before the server resets it.

If GL advertises this extension we'll use it to synchronize X with GL
rendering instead of relying on the XSync() behavior with open source
drivers.
Some driver bugs were uncovered while working on this so if we have
had to reboot the ring a few times, something is probably wrong and
we're likely to just make things worse by continuing to try. Let's
err on the side of caution, disable ourselves and fallback to the
XSync() path in the compositor.

glGetIntegerv (GL_DEPTH_BITS, ...) and friends are deprecated in GL3; we
have to use glGetFramebufferAttachmentParameteriv() instead, like we do
for offscreen framebuffers.

If we can't put up a popup because grabbing the pointer fails we
immediately dismiss the popup but the client might have made requests
already, in particular it might have commited the surface and in that
case we should ignore it.

When a client sets an input region or a opaque region to NULL, it
should still be considered a change to the corresponding region on the
actor. This patch makes sure this state is properly forwarded.

This was introduced in commit c6793d477a
to prevent window self-maximisation. It turns out that that bug seems
to have been fixed meanwhile in a different way since the reproducer
in https://bugzilla.gnome.org/show_bug.cgi?id=461927#c37 now works
fine with this special handling removed.
In fact, failing to set window->fullscreen immediately when loading
the initial set of X properties causes us to create a UI frame for a
window that sets _NET_WM_STATE_FULLSCREEN.
This, in turn, might cause the fullscreen constrain code to fail if
the window also sets min_width/min_height size hints to be the monitor
size since the UI frame size added to those makes the rectangle too
big to fit the monitor. If the window doesn't set these hints, we
fullscreen it but the window will get sized such that the UI frame is
taken into account while it really shouldn't (see the reproducer
above).

We want to use the Cogl GL3 driver, if possible, and then go through a
known list of Cogl drivers, before giving up and using COGL_DRIVER_ANY.
Based on original patch from Emmanuele Bassi.
We have to create and tear down the whole context when trying
out the drivers though because the extension checks do not happen
until cogl_context_init.

We want to be able to retrieve the XVisualInfo used when creating the
GL context under GLX and EGL-X11, so that we can use the visual before
we have an onscreen frame buffer.
