ace7f6861e binding: Remove conditional from the default transform function
Avoiding checking for INVERT_BOOLEAN each and
instead choose the correct function in constructed().

36593a3aba binding: Remove GObject data usage
It isn't actually doing anything, instead it is
being managed without actually being used.
This has the result that GBinding is now more
thread-safe.

f1c2e70345 Connect to the detailed notify signal in GBinding
This avoids the notify handler being called for each
and every emitted notify.

b07ba8ed3b Fix g_binding_unbind() when the source and target are the same
It tried to remove a weak ref, but it is only taken if the
source and target object are different.

d9de830b65 Convert remaining uses of 'Rename to:'
This was replaced by (rename-to) in 2013 (see bug 676133).

They're also causing gtk-doc trouble, so let's get rid of them.

d8c14f1378 gbinding: warn on failed value transformation
GBinding warned if g_value_transform() returned FALSE, but it didn't
warn if there was no transformation available at all. Fix that and
test it.

8e17040c15 Fix overloading of "source" and "target" terminology in GBinding
GBindingTransformFunc called its arguments "source_value" and
"target_value", but in the transform_from function of a bidirectional
binding, "source_value" comes from the target object, and
"target_value" comes from the source object, which quickly gets
confusing if you need to use g_binding_get_source(), etc, in the
function.

Of course developers can call their transform function arguments
whatever they want, but many will copy from the headers/docs to start
out, so use less confusing names here ("from_value" and "to_value").

Also, fix the documentation to describe the bidirectional case
correctly.

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.

I've added a testcase as well.

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.

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.
