If a second `set_{sync,complete}_pending` was queued before the idle
handler had flushed the first then one of them would be forgotten.
It would stay queued forever and never emitted as a notification.
This could happen repeatedly causing a slow leak. But worse still,
`clutter-stage-cogl` would then have `pending_swaps` permanently stuck
above zero preventing the presentation timing logic from being used.
The problem is that a boolean can only count to one, but in some cases
(triple buffering, whether intentional or accidental #334) we need it to
count to two. So just change booleans to integers and count properly.

This basically reverts commit 54735dec, which tried to avoid the
GLib-defined types in favor the standard C ones. One exception to this
is the bool type, for which the commit introduces a new type CoglBool.
Let's just get rid of this type in favor of having consistency with the
GLib types. Note by the way that neither CoglBool nor gboolean (which
has a size of `int`) are completely compatible with bool (size `char`).

Commit 25f416c13db added additional compilation warnings, including
-Werror=return-type. There are several places where this results
in build failures if `g_assert_not_reached()` is disabled at compile
time and the compiler misses a return value.

Since now we don't set the swap throttled value based
on sync-to-vblank, we can effectively remove it from
Cogl. Throttling swap buffers in Cogl is as much a
historical artifact as sync-to-vblank. Furthermore,
it doesn't make sense to disable it on a compositor,
which is the case with the embedded Cogl.
In addition to that, the winsys vfunc for updating
whenever swap throttling changes could also be removed,
since swap throttling is always enabled now.
Removing it means less code, less branches when running,
and one less config option to deal with.
This also removes the micro-perf test, since it doesn't
make sense for the case where Cogl is embedded into the
compositor.

This macro was introduced so as to be able to be built without GLib.
However, this feature was long ago removed, and in Mutter we depend on
it anyway, so let's get rid of it in favor of more consistency.
Before we just set it to "none", but this was not enough since various
calls will depend on not just the context being active, but the main
rendering surface.

We just arbitrarily chose the first EGL config matching the passed
attributes, but we then assumed we always got GBM_FORMAT_XRGB8888. That
was not a correct assumption. Instead, make sure we always pick the
format we expect.

Because the threaded-swap-wait functionality requires XInitThreads(),
and because it isn't clear that it is a win for all applications,
add a API function to conditionally enable it.
Fix the cogl-crate example not to just have a hard-coded dependency
on libX11.

It's a good guess that the buffer swap will occur at the next vblank,
so use glXWaitVideoSync in a separate thread to deliver a sync event
rather than just letting the client block when frame drawing, which
can signficantly change app logic as compared to the INTEL_swap_event
case.

When we don't have GLX_OML_sync_control, we still can set the
frame presentation time, but we always use the system monotonic time,
so return that from get_clock_time().

As previously commented in the code, SGI_video_sync is per-display, rather
than per-renderer. The is_direct flag for the renderer was tested before
it was initialized (per-display) and that resulted in SGI_video_sync
never being used.

Different libEGL will do different things for eglGetDisplay since it has
to guess what kind of display it's been handed. Better to just use the
API that makes it explicit.

The WL_bind_wayland_display spec says that EGL images should be created
using EGL_WAYLAND_BUFFER_WL as the target and a NULL context. Mesa
seems to be lenient and accept any context, however some other stacks
aren't so forgiving and fail if anything apart from EGL_NO_CONTEXT is
used.

Mutter (and libmutter users) are the only users of this version of
cogl, and will more or less only use the cogl-1.0, cogl-2.0 and cogl
experimental API variants, and having the possibility of having
different API versions of the same API depending on what file includes
it is error prone and confusing. Lets just remove the possibility of
having different versions of the same API.

Move the KMS interaction from cogl into mutter, where most of the other
KMS interaction already takes place. This also removes dead code which
were only excercised when non-mutter callers used the cogl KMS backend.
The cogl KMS API was updated to pass via MetaRendererNative instead of
via the different cogl objects.

In cogl use cogl-config.h and in clutter use clutter-build-config.h. We
can't use clutter-config.h in clutter because its already used and
installed.

If you include a file that might define __INSIDE_COGL_H__, don't
undefine it if it wasn't defined in that file. This makes it possible
to include for example cogl-gles2.h from some other file which defines
__INSIDE_COGL_H__.
