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.
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.
Use a DeviceManager sub-class similar to the Win32 backend one, which
creates two InputDevices: a core pointer and a core keyboard.
The event translation code then uses these two devices to fill out the
.device field of the events.
Throw in enter/leave tracking, given that we need to update the device's
state.

Implementation of event loop which works with GLib events, native OS X
events and Clutter events.
The event loop source code comes from the equivalent code in the Quartz
GDK backend from GTK+ 2.22.1, which is LGPL v2.1+ and thus compatible
with Clutter's licensing terms.
The code has been tested with libsoup, which did not work before together
with Clutter.

Since using addresses that might change is something that finally
the FSF acknowledge as a plausible scenario (after changing address
twice), the license blurb in the source files should use the URI
for getting the license in case the library did not come with it.
Not that URIs cannot possibly change, but at least it's easier to
set up a redirection at the same place.
As a side note: this commit closes the oldes bug in Clutter's bug
report tool.

* clutter/osx/clutter-stage-osx.c (EVENT_HANDLER): Since events are
delivered to ClutterGLView, pass the associated ClutterStage directly
to event translation. Avoids relying on being embedded in
ClutterGLWindow, which makes it easier to implement clutter-gtk.

comment, on OSX backend the Shift modifier is included in 'keyval'
making it identical to 'unicode_value' Instead of <Shift>a or
<Shift>3 you'd get <Shift>A and <Shift>#

Adapt to new multistage backend API. Don't keep a pointer to
default stage. Derive from ClutterActor instead of ClutterStage.
Implement ClutterStageWindow interface. Paint, resize and
otherwise manipulate the wrapper rather than self when necessary.
(clutter_backend_post_parse): Create our singleton GL context
here. We could probably create the context when the default
stage is created, but I think this is more clean.

Fill in ClutterEventAny::stage on our events.
Consistently use 'stage_osx' and 'wrapper' as variable names
when referring to ClutterStageOSX and ClutterStage objects
respectively.
