This fixes caps operations when different elements advertise some
of their caps' properties differently (eg, for audio channels, either
a range from 1 to 2, or a list of 1 and 2).

When we do not care about the actual resulting set,
but only whether it is empty of not, we can skip a fair bit
of GValue juggling.
Add a function that does so, since we cannot just pass NULL
to the existing API as it may be part of the API contract.

gobject-introspection won't parse them properly otherwise.
Still need to force the right type though (either GstClockTime or
guint64), but Type: xyz has no effect for me here, so someone with
a newer g-i needs to test this.
Some other defines are also missing, e.g. GST_CLOCK_TIME_NONE.
The internal proxy pad target is simply a cache of the internal proxy pad
peer. This patch uses the well implement GstPad peer handling to obtain the
target. This fixes issues with target not being set in both direction when
two ghostpads are linked together (empty bin).

It's not really used outside of core at all, and has
serious namespace issues. If anyone feels the need to
revive this one, please use a less generic name space.
API: deprecate gst_filter_run()
API: deprecate GstFilterFunc
It's only used internally anyway and the helper struct
has namespace issues.
API: deprecated gst_plugin_feature_type_name_filter()
API: deprecated GstTypeNameData
We never get a tag name quark from a caller, it's always a
string, from which we'll try to look up our tag info in the
hash table, so change the hash table key from quark to string.
Avoids a bunch of pointless string => quark lookup in the
global quark table. We need to do an extra string => quark
conversion now when we copy a taglist, but in that case we're
in a slow path anyway.
This will make sure we spawn a new plugin scanner helper for each plugin
to be introspected, which helps with making sure we don't load too many
shared objects (libs, plugins) at the same time on systems where there
is a hard limit like on Android.
A better version might re-use the scanner for up to N times, though
it's not clear whether that would actually improve things dramatically.

The second caps ownership is transfered, no need to require it to
be writable from the caller function. Instead, _append and _merge
make it writable on their own.
Discovered because of an assertion on encoding-profile.c in
_get_input_caps using _merge but not passing writable caps.
Handle virtual links between ghost and proxypads when iterating pads instead of
when linking. Besides using less code this provides a more accurate picture.
Don't export those 35-something random _gst_parse_yy* symbols. These were
never in any header files and also blacklisted from our .def files, in
case anyone wonders.
GstBuffer pointers can now be printed using GST_PTR_FORMAT. This is used
in the very useful GST_SCHEDULING debug logs in gstpad.c and allows for
easier and more information tracking of buffer progress through a
pipeline with just debug logging.
This allows the setcaps handler and notify::caps to link
the pad downstream and doesn't require hacks to always
provide a peer to the pad, like in decodebin2.
