Currently, Meta/Cogl/Clutter makes use of cairo_rectangle_int_t despite
the existance of MetaRectangle.
In order to make MetaRectangle usable in Cogl/Clutter as well, Mtk would
provide such base types that are shared across the various private
libraries

This fixes the following
1. Minimize window; minimize animation starts
2. Do something that immediately destroys the animated actor (e.g. terminate)
3. This triggered the timeline of the animation to emit a "stopped"
signal while all transitions of the actor were destroyed
Previously we'd implicitly animate the scale again (set_scale(..)) which
created a new transition The hash table iterator didn't like this and
abort():ed

Except for the tests that launches `mutter`, use a custom shell
implementation. It's roughly a copy of default.c with some cleanups on
top. A custom shell allows for a bit more freedom when doing testy
things.

With the ClutterEvent subtype structs sealed, this remains the only useful
struct type that is now usable on the Javascript side. Make all
ClutterActorClass event vmethods use ClutterEvent, and update all users
to this change.

The default cogl blend string is
`RGBA = ADD (SRC_COLOR, DST_COLOR*(1-SRC_COLOR[A]))` which is alpha
blending with premult fragment results. We do not clear the src
framebuffer and even if we did set alpha to 1 in the src fb, the
resulting alpha would be 1 and we want to check the alpha of the
fragment color.
Just turn off any kind of blending instead and write out the fragment
color to the fb.

To obtain a float between 0 and 1 we have to devide the integer by the
highest possible value instead of the number of values.
Fixes off by one errors in the tests on some hardware/driver
combinations.

So we can properly handle matching DRM and WL_SHM formats in a unified
manner.
Add extensive testing between these and existing pre-multiplied alpha
formats, i.e. all formats we support on Wayland.
Note that unfortunately for some format combinations the value in the
alpha channel is not cleared as expected, likely because of fast-paths
in Cogl. If both source and destination format is opaque, it always
works, however. This thereby includes all cases where they are the same.

We can schedule an update from the cursor manager, but that doesn't mean
there will be an actual plane assignment changed at the time of the
update processing, since for example we might have "touched" a CRTC, but
already left it before the processing started, meaning we have nothing
to change after all.
Add a test case that checks that this works properly.

It can be quite slow to set up the test environment inside the VM, as
well as outside, leaving very little time for the test itself. While
it'd be nice to not run the mock env etc outside the VM, let's just bump
the timeout for now, to avoid unnecessary timeout failures.

If we turn of a CRTC, we might have invalidated the cursor manager for
the same CRTC, but that should not mean a cursor plane is assigned when
turning off the CRTC.
Add a test case for this.

Real time scheduling is needed for better control of when we commit
updates to the kernel, so add a property to MetaThread that, if the
thread implementation uses a kernel thread and not a user thread, RTKit
is asked to make the thread real time scheduled using the maximum
priority allowed.
Currently RTKit doesn't support the GetAll() D-Bus properties method, so
some fall back code is added, as GDBusProxy depends on GetAll() working
to make the cached properties up to date. Once
https://github.com/heftig/rtkit/pull/30 lands and becomes widely
available in distributions, the work around can be dropped.

Also add an API to inhibit the kernel thread from being used, and make
MetaRenderDeviceEglStream inhibit the kernel thread from being used if
it's active.
The reason for this is that the MetaRenderDeviceEGlStream is used when
using EGLStreams instead of KMS for page flipping. This means the actual
page flipping happens as a side effect of using EGL/OpenGL, which can't
easily be done off thread.

This will be necessary in order to default to 'kernel' and then switch
to 'user' if the thread instance can no longer be properly multi
threaded.
To avoid having the same thread impl creating and destroying
GMainContext's, this also means always creating a GMainContext for the
thread-impl. When running in user-thread mode, the GMainContext is
wrapped in a wrapper source and dispatched as part of the real main
thread GMainContext, and when in kernel-thread mode, it runs
independently in the dedicated thread.
This has the consequence that the wrapper source will always have the
priority of the highest impl context GSource, but only after it has
dispatched once. Would we need it earlier than that, we either need a
way to introspect existing sources in a GMainContext and their
priorities, or manually track known sources in MetaThreadImpl.
The wrapper source will never be below 0, as that'd mean it could reach
INT_MAX priority if it had no more sources attached to it, meaning it'd
never be dispatched again.

While the default when passing NULL will be the main context of the main
thread, make it possible to specify another main context, so that
result handlers can be invoked on the right thread.

Callbacks could be queued to be invoked either on the impl side or the
main thread side of the thread; change this to take a GMainContext,
which effectively means a callback can be queued to be invoked on any
thread that has a GMainLoop running on its own GMainContext.
Flushing is made to handle flushing callbacks synchronously on all
threads. This works by keeping a hash table of queued callbacks per
thread (GMainContext); when flushing (from the main thread), callbacks
on the main thread context is flushed, followed by synchronization with
all the other threads.
meta_thread_flush_callbacks() is changed to no longer return the number
of dispatched callbacks; it becomes much harder when there are N queues
spread across multiple threads. Since it wasn't used for anything, just
drop the counting, making life slightly easier.
Feedback to thread tasks are however always queued on the callers
thread.
