Since everything GstXML related has been deprecated, we can now skip the
libxml includes from the public headers when GST_DISABLE_DEPRECATED is
defined.
See #463435.
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.
A pad is 'negotiable' when its container element is in a state greater
than GST_STATE_READY

There's not much point in using GST_DEBUG_FUNCPTR with GObject
virtual functions such as get_property, set_propery, finalize and
dispose, since they'll never be used by anyone anyway. Saves a
few bytes and possibly a tenth of a polar bear.
It is not too obvious that getting and releasing request pads is not entierly
symetrical regarding to the pad refcount. Add a note about that to the docs.
This might deserve a FIXME-0.11 too.
The first time one calls gst_element_factory_make(), gst recreates the plugin
feature and the element factory. As a side effect we ref the class to fill
in detail we already have filled from the registry cache. This patch changes
the behaviour to just update the existing entries. The factory is now attached
to the type and set in gst_element_base_class_init().
Add a start_time field and some methods. The start_time will contain the
running_time of when the element last went to paused. This time can be user to
report the position in PAUSED but also to do more correct clipping and
stepping later.
Add a gst_element_lost_state_full() with an extra argument to control
distribution of a new base_time. We will need this for flushing step
operations.
API: GstElement::gst_element_lost_state_full()
When an element lost its state but was busy doing a state change, still post the
async-start message with the base_time reset flag or else we might end up with
an old base_time.
this can happen when a sink is goin async to paused and then a flushing seek is
performed. This would cause the base_time to remain unmodified because the
async-start message was not sent.

category so they don't get lost in debugging.

Avoid leaking the parent ref when we fail changing the state of the
element using gst_element_sync_state_with_parent(). Fixes#551978.

Remove GST_DISABLE_(ENUMTYPES|INDEX|URI) everywhere.
Disabling the indexers and URI handler code will only reduce the
required amount of memory by a very small amount but on the other hand
requires much more maintaince work. Apart from that many places of
code are broken when disabling them.
Disabling the enum types doesn't reduce the required amount of memory
by more than a few bytes and makes it hard to fix bugs like #539772,
i.e. use the enums as GObject properties.
Original commit message from CVS:
* gst/gstelement.c:
* gst/gstelement.h:
Deprecated gst_element_get_pad() as it can't be used sanely. It's not
clear of the reference to the resulting pad must be released later
or not, resulting in possible leaks. Fixes bug #533865.
Original commit message from CVS:
* gst/gstelement.c: (gst_element_base_class_init),
(gst_element_class_add_pad_template):
* gst/gstpadtemplate.c:
Make it possible (and recommended) to set element details and add
pad templates in the class_init functions by copying the details/pad
templates in GstElement's base_init.
Also make it possible to replace existing pad templates by adding
a new one with the same name. This was done in a hackish fashion
in same elements before already.
Don't reference pad templates that are added a second time. A
new pad template has a refcount of one and is not floating anymore
and to be owned by the element's class. Make this more explicit by
mentioning it in the docs of gst_element_class_add_pad_template().
These changes are backwards compatible. Fixes bug #491501.
* tests/check/gst/gstelement.c:
Add unit test for setting element details, adding pad templates and
replacing them in a subclass.
