If a button press happen on stage and the pointer is moved outside
the stage while holding the mouse button, the motion and release
events are still delivered to actors. Do the same X11 soft grab
emulation for touch events.

On various systems, trying to release a mutex that hasn't been acquired
will result in a run-time error.
In order to avoid this, we trylock() the Big Clutter Lock™ and
immediately unlock() it, regardless of the result; if the lock was
already acquired, trylock() will immediately fail, and we can release
it; if the lock was not acquired, trylock() will succeed, and we can
release the lock immediately.
This is necessary to maintain binary compatibility and invariants for
Clutter applications doing:
clutter_init()
clutter_threads_enter()
...
clutter_main()
...
clutter_threads_leave()
instead of the correct:
clutter_init()
clutter_threads_enter()
...
clutter_threads_leave()
clutter_main()
clutter_threads_enter()
...
clutter_threads_leave()
With Clutter ≥ 1.12, the idiomatic form is:
clutter_init()
...
clutter_main()
given that the public Big Clutter Lock™ acquire/release API has been
deprecated, and nobody should take the lock outside of Clutter itself.

-Make things a bit cleaner by generating clutter.def in the intermediate
build folder
-Fix the include paths as config.h is now in clutter/
-Make things a little bit more consistent between vs9 and vs10 in terms of
the "install" stage
When the last touch has been released the stage on the
corresponding master device (eg. the virtual core pointer) is set
to NULL and no mouse events can be delivered until an ENTER event
has occurred and the stage pointer restored.
This is due to the fact that the master devices can send both
touch events and mouse events, forwarding events coming from the
attached slave devices.
To restore delivery of mouse events we need to ensure that the
stage is set on each ButtonPress, ButtonRelease and Motion event
coming from master devices.

When using the new ActorAlign flags we must get the real alignment for
the horizontal axis, as clutter_actor_allocate() will compute the
effective alignment by itself; if we use the effective alignment then
ClutterActor.allocate() will swap it, and undo our work.
When using the old BinAlignment flags we should reverse the alignment
depending on whether the text direction of the child is RTL or LTR.

It should be possible to destroy the actor currently being dragged from
within the ::drag-end signal. In order to do this, we need to keep a
reference on the action for the duration of the emit_drag_end() function
as well as resetting the action's state inside the dispose()
implementation, to avoid trying to access cleared data.

Modified Return key presses don't trigger ::activate so we would end
up adding an unprintable character to a single paragraph mode pango
layout which renders it as a box.
https://bugzilla.gnome.org/show_bug.cgi?id=623344
The code for calculating the content box when the aspect ratio is
greater than 1 was broken. The same code that did the calculation for
aspect ratio less than 1 should be used in all cases.
