Add a GstControlBinding class. This is a preparation for making the
controlsources generate double valued control curves and do the gparamspec
mapping in the control binding. Now the API in GstObject is again mostly
for convenience.
Make that implizit with attaching/detaching controlsources. This is a lot easier
and has less invalid state (controlled property without control source).
This make the controller even more lightweight (no extra object, no extra lock,
less indirections). For object that don't use the controller the only 'overhead'
is a 3 unused fields in the gst_object structure.
Move the controller to gstobject as a simple delegate. The controller and
controlsource are not classes in core. The controlsources stay separate as a lib
for now. This way we can avoid the qdata lookups.
Also remove controller_init(). There is no more need to link to controller for
elements.
Also sanitize the API. We now have functions to add properties like we had
methods to remove that. That avoids then ref count hacks we had in _new.
Make GstObject extend from GInitiallyUnowned, remove the FLOATING flag and use
GObject methods for managing the floating ref.
Remove class lock, it was a workaround for a glib < 2.8 bug.
Remove the parent-set and parent-unset signals, attempt to implement with notify
but disabled because deadlocks in deep-notify.
Pipeline serialisation to and from XML is horribly broken for all
but the most simple use cases, and will likely never be fixed.
Make sure everyone playing around with these tools is aware of
this, to avoid frustration. See countless bug reports in bugzilla.
Fixes bug #622685.
This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.
Also adds -Wwrite-strings as a warning flag in configure.ac.

2nd attempt to have a xml-less build as a joined effort of #413123
and #421480.
Original commit message from CVS:
Patch by: Peter Kjellerstedt <pkj at axis com>
* gst/gstobject.h:
Don't define xmlNodePtr to gpointer if the core was built with
--disable-loadsave and --disable-registry, this will break
applications that want to use libxml2 but are buildling against a
core that doesn't use libxml2. Use an intermediary type GstXmlNodePtr
instead so we don't have to mess with the libxml2 namespace
(#361675).
Original commit message from CVS:
* gst/gstobject.h:
Add cast to make compiler happy - refcount variable was a gint
in GstObject but is a guint in GObject and g_atomic_int_get()
wants a gint *.

* gst/gstevent.h (struct _GstEvent): Only one pointer of padding.
* gst/gststructure.h (struct _GstStructure): Only one pointer of
padding.
* gst/gstquery.h (struct _GstQuery): Only one pointer of padding.
* gst/gstpluginfeature.h: Remove a comment in PluginFeature.
* gst/gstplugin.h (struct _GstPluginClass): Add some padding.
* gst/gstobject.h: (struct _GstObject): Only one pointer of
padding; reduces object size by about 30%. We don't expect
anything else to go into gstobject.
* gst/gstminiobject.h (struct _GstMiniObject)
(struct _GstMiniObjectClass): Only one pointer of padding; the
payload is only a pointer and two ints anyway. For the class there
are only two methods as well.
* gst/gstelement.h (struct _GstElementClass): Removed
the state_changed signal callback, it is not used.
Original commit message from CVS:

Update for new API and API changes.
* gst/gstobject.h:
Documentation fix: GST_TRYLOCK -> GST_OBJECT_TRYLOCK

Documentation typo fix.

Documentation fixes for arguments.

* *.h:
* *.c: Ran scripts/update-macros. Oh yes.
* gst/gstobject.h (GST_OBJECT_GET_LOCK, GST_OBJECT_LOCK)
(GST_OBJECT_TRYLOCK, GST_OBJECT_UNLOCK): Renamed from
GST_GET_LOCK, etc.
* scripts/update-macros: New script. Run it on your files to
change GST_LOCK to GST_OBJECT_LOCK, and the same for UNLOCK as
well.

It is volatile, after all.
