25a3c8720c binding: Make unbind() release the reference on GBinding
The automatic memory management of GBinding is not optimal for high
order languages with garbage collectors semantics. If we leave the
binding instance inert but still referenced it will be leaked, so one
solution that does not throw away the baby of C convenience with the
bathwater of language bindability is to have unbind() perform an
implicit unref().

Hopefully, C developers will read the documentation and especially the
note that says that after calling unbind() the reference count on the
GBinding instance is decreased.

a360b314aa binding: Add an explicit unbind()
Higher order languages with garbage collection can have issues releasing
a binding, as they do not control the last reference being dropped on
the binding, source, or target instances.

8e716cbb49 Fix annotations for source/target in g_object_bind_property_*
We use gpointer for convience of the C API users, but introspection
users will not like it.

8f21e8145c gobject: remove -DG_DISABLE_CONST_RETURNS
GObject had a few cases of depending on G_CONST_RETURN not being defined
to 'const'.  Remove those in preparation for deprecation of
G_CONST_RETURN.

4bc9654c63 binding: Add a default marshaller for the closure API
The g_object_bind_property_with_closures() function should set a
marshaller if the two GClosures don't have one already. This simplifies
the caller code and avoids duplication.

We need to add a new marshaller to the gmarshal.list matching the
signature of the GBindingTransformFunc function.

90f7f171e6 binding: Add G_BINDING_INVERT_BOOLEAN
Since GSettings got the same functionality and flag in commit ca3b7b75b
GBinding should also have the ability to automatically invert a boolean
value without requiring a custom transformation function.

3be3ad61d1 binding: Add a closure-based variant of bind_property_full()
Since using the function pointer version muddles the memory management
requirements of language bindings, we should implement a GClosure-based
variant on top of g_object_bind_property_full().

f587cb57f2 binding: Add SYNC_CREATE to the flags
When creating a binding between two object properties we might want to
automatically synchronize the two values at the moment of the binding
creation, instead of waiting for the next change.

The G_BINDING_SYNC_CREATE flag does exactly what it says on the tin.

33aa4b4c66 binding: Use a hash table
Since an object instance might have a lot of bindings, using a list
might become a performance issue when removing them. Using a simple
hash table guarantees constant time lookup, which is the most common
operation.

6d1d9cf1b5 gobject: Add GBinding
GBinding is a simple, opaque object that represents a binding between a
property on a GObject instance (source) and property on another GObject
instance (target).
