9177367984 ghostpad: improve debug
Log a debug line when there is no target pad and when this makes the default
implementation fail.
Take the internal pads directly when we can.

25989f3c8d ghostpad: avoid calling setcaps too many times
Don't call setcaps, the caps event will take care of propagating the caps on all
pads.

5642f9db8c ghostpad: remove unused code

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.

4c1e594ae5 ghostpad: Make all the internal caps functions public
This is useful if ghostpad/proxypads should be used but

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.

9ef1346b1f context: use context on buffers instead of caps

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
If we're building against GLib >= 2.26.0, we can use the more efficient
g_object_notify_by_caps(), which avoids the param spec lookup.

71f3a6f0f7 Don't include <libxml/parser.h> from public headers if GST_DISABLE_DEPRECATED is defined

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.

24b357a444 gstghostpad: Register debug funcptr only once.
This makes ghostpad/proxypad creation 5 times faster and avoids contention
over the global funcptr lock.

I also moved the two class init down in the code to avoid having to forward
declare all the various functions.

daecaf0e8a Remove GST_DEBUG_FUNCPTR where they're pointless
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.

fcc5d783df pad: add variants of gst_pad_get_caps() that don't copy caps. Fixes #590941
In most places in core and baseclasses we just need the caps to do caps-

This patch also switches the code to use the new functions.

a0ed1a44a5 ghostpad: Always get the proxypad's ghostpad via the ghostpad in the src caps change notify handler
Before the signal handler would get the ghostpad passed as second
argument but it could've already been unreffed and destroyed.
This would then lead to crashes and all that.

Now we get the ghostpad from the proxy pad, which we get from the
target pad as it's peer.
