fc04f015a6 gdk: Fix compilation on non-X11 platforms
The GDK backend may not work on non-X11 platforms, yet, but it's not a
good reason to let it introduce random build breakage.

0e4c6d0a87 Deprecate clutter_threads_enter()/leave()
Acquiring the Clutter lock to mark critical sections is not portable,
and not recommended to implement threaded applications with Clutter.

The recommended pattern is to use worker threads, and schedule UI
updates inside idle or timeout handlers within the main loop. We should
enforce this pattern by deprecating the threads_enter()/leave()
functions. For compatibility concerns, we need internal API to acquire
the main lock during frame processing dispatch.

26d8ad7479 Be resilient in case there is no device manager
It's possible to run Clutter with the 'null' input backend, which means
that clutter_device_manager_get_default() may return NULL. In the future
we may add a default dummy device manager, but right now it's safer to
just add a simple NULL check in the places where we ask for the device
manager.

adb6ffbd0e backend: Unify the event initialization
Input backends are, in some cases, independent from the windowing system
backends; we can initialize input handling using a model similar to what
we use for windowing backends, including an environment variable and
compile-/run-time checks.

This model allows us to remove the backend-specific init_events(), and
use a generic implementation directly inside the base ClutterBackend
class, thus further reducing the backend-specific code that every
platform has to implement.

This requires some minor surgery to every single backend, to make sure
that the function exposed to initialize the event loop is similar and
performs roughly the same operations.

8eb71af23d gdk/events: Clean up the event handling code
We need debugging notes, to see what's happening when handling events.

We need to queue a (clipped) redraw when receiving a GDK_EXPOSE event.

We need to check the device (both master and source) of the event using
the GdkEvent API, and pass them to the ClutterEvent using the
corresponding Clutter API.

610a9c17ba Add a new GDK backend
This commit introduces a new flavour for Clutter, that uses GDK
for handling all window system specific interactions (except for
creating the cogl context, as cogl does not know about GDK), including
in particular events. This is not compatible with the X11 (glx)
flavour, and this is reflected by the different soname (libclutter-gdk-1.0.so),
as all X11 specific functions and classes are not available. If you
wish to be compatible, you should check for CLUTTER_WINDOWING_X11.
Other than that, this backend should be on feature parity with X11,
including XInput 2, XSettings and EMWH (with much, much less code)
