fcadf09779 ghostpad: Use gst_pad_set_caps() instead of manually changing caps 
gst_pad_set_caps() does essentially the same but additionally calls
the pad's setcaps function.

Fixes bug #658076.

3d2127f865 Revert "query: allow _make_writable on query handlers" 
This reverts commit cf4fbc005c.

This change did not improve the situation for bindings because
queries are usually created, then directly passed to a function
and not stored elsewhere, and the writability problem with
miniobjects usually happens with buffers or caps instead.

a216426bb6 ghostpad: API: Expose gst_proxy_pad_get_internal() 
This allows to get the internal pad of ghostpads and
proxypads without using gst_pad_iterate_internal_links()
and is much more convenient.

The internal pad of a ghostpad is the pad of the opposite direction
that is used to link to the ghostpad target.

c4751ec8c1 Revert "context: use context on buffers instead of caps" 
This reverts commit 9ef1346b1f.

Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.

6ab7e6c15d Remove pad_alloc, this can now be done better 
Remove pad_alloc and all references. This can now be done more efficiently and
more flexible with the ALLOCATION query and the bufferpool objects. There is no
reverse negotiation yet but that will be done with an event later.

7dd38cdcf4 ghostpad: Fix pad callbacks so they handle when parent goes away 
1) We need to lock and get a strong ref to the parent, if still there.
2) If it has gone away, we need to handle that gracefully.

This is necessary in order to safely modify a running pipeline. Has been
observed when a streaming thread is doing a buffer_alloc() while an
application thread sends an event on a pad further downstream, and from
within a pad probe (holding STREAM_LOCK) carries out the pipeline plumbing
while the streaming thread has its buffer_alloc() in progress.

b2ab72b916 pad: remove get_caps_reffed variants 
Make the _get_caps functions behave like the _get_caps_reffed variants and
remove the _reffed variants. This means that _get_caps doesn't return a writable
caps anymore and an explicit _make_writable() is needed before modifying the
caps.

fd6334cb7c pads: use new g_object_notify_by_pspec() for caps notifies if available

g_object_notify_by_caps(), which avoids the param spec lookup.

defined.

5f4a965f67 gstxml: Deprecate GstXml and related functions 
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.

This makes ghostpad/proxypad creation 5 times faster and avoids contention
over the global funcptr lock.

virtual functions such as get_property, set_propery, finalize and
