2b81d90dd7 Eliminate G_CONST_RETURN
The G_CONST_RETURN define in GLib is, and has always been, a bit fuzzy.

We always used it to conform to the platform, at least for public-facing
API.

At first I assumed it has something to do with brain-damaged compilers
or with weird platforms where const was not really supported; sadly,
it's something much, much worse: it's a define that can be toggled at
compile-time to remove const from the signature of public API. This is a
truly terrifying feature that I assume was added in the past century,
and whose inception clearly had something to do with massive doses of
absynthe and opium — because any other explanation would make the
existence of such a feature even worse than assuming drugs had anything
to do with it.

Anyway, and pleasing the gods, this dubious feature is being
removed/deprecated in GLib; see bug:

  https://bugzilla.gnome.org/show_bug.cgi?id=644611

Before deprecation, though, we should just remove its usage from the
whole API. We should especially remove its usage from Cally's internals,
since there it never made sense in the first place.

0e1bbcdc02 Add declaration of clutter_binding_pool_get_type()
The function is automagically created by G_DEFINE_TYPE(), but
it should also be declared in the header.

a4c8a70c83 Turn ClutterBindingPool a GObject
ClutterBindingPool is already "problematic" in terms of memory
management for language bindings and gobject-introspection. It
also lacks a GType.

Turning ClutterBindingPool into a GBoxed would not make much
sense, since it does not adhere to the copy/free semantics. It
could be referenced/unreferenced, but in that case we can just
as well use GObject as a base class instead of reimplemeting
a ref-counted object and then boxing it.

ClutterBindingPool is obviously a terminal class, so we just
hide the instance and class structures.

c988b7b736 Remove BindingPool::list_actions()
The clutter_binding_pool_list_actions() was not implemented. The
utility of a call listing all the action names is also debatable:
all the functions related to the key bindings take the key symbol
and modifiers -- except the block_action() and unblock_action()
pair.

e56fe478ef Allow overriding actions inside a BindingPool
As of now, a key binding installed into a BindingPool is always there
and cannot be changed.

This is problematic for sub-classes trying to override the callback
or the action for a given key binding.

This commit adds the ability to override the closure for an existing
key binding inside a binding pool -- assumed the caller knows the
key symbol and modifiers used to install the key binding in the first
place.

* clutter/clutter-binding-pool.h: Fix the ActivateFunc
	documentation by adding a "return value" annotation.

* clutter/Makefile.am:
	* clutter/clutter.h: Add ClutterBindingPool to the build.

	* clutter/clutter-binding-pool.c:
	* clutter/clutter-binding-pool.h: Add ClutterBindingPool, a data
	structure meant to hold (key symbol, modifiers) pairs and associate
	them to a closure. The ClutterBindingPool can be used to install
	key bindings for actors and then execute closures inside the
	key-press-event signal handlers, removing the need for big
	switch() or if() blocks for each key.

	* clutter/clutter-event.c: Consistently use "key symbol" instead
	of "key value".

	* clutter/clutter-event.h: Add more modifier masks.

	* clutter/clutter-marshal.list:

	* tests/conform/Makefile.am:
	* tests/conform/test-binding-pool.c:
	* tests/conform/test-conform-main.c: Add ClutterBindingPool
	conformance test.

	* tests/interactive/Makefile.am:
	* tests/interactive/test-binding-pool.c: Add interactive test (and
	example code) for the ClutterBindingPool usage.
