6e57ce32e5 caps: Merge structures when intersecting instead of appending them
This prevents adding duplicates over and over again to the resulting
caps if they already describe the new intersection result.

While this changes intersection from O(n*m) to O(n^2*m), it results in
smaller caps, which in the end will decrease further processing times.

For example in an audioconvert ! audioconvert ! audioconvert pipeline,
when forwarding the downstream caps preference in basetransform
(see e26da72de25a91c3eaad9f7c8b2f53ba888a0394) this results in
16 instead of 191 caps structures.

9597545d23 structure: more cleanups
gst_structure_get_type() -> _gst_structure_type to avoid method calls for
getting the GType that initialized at the start.
Hide some structure fields in private data so that we can change the
implementation.
Move structure equality check from caps.c to structure.c where it belongs.

e2452c8c78 caps: cleanups
We don't need to check if the type is 0, the init function is only called once
in the beginning.

09d83e589a gstcaps: new API : gst_caps_intersect_full
Just like gst_caps_intersect, but adds a new parameter 'mode'
that allows selecting the intersection algorithm to use.

Currently we have GST_CAPS_INTERSECT_MODE_ZIG_ZAG (default) and
GST_CAPS_INTERSECT_MODE_FIRST.

API: gst_caps_intersect_full
API: GstCapsIntersectMode

2bbfa3304c caps: don't create broken caps for invalid media types
Check if structure has been created before appending it to the caps. Free the
caps in the case of an error to not conceal it be returning empty caps.

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

libxml includes from the public headers when GST_DISABLE_DEPRECATED is
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.

66fc4c8ba2 info: add new TRACE log level and move refcounting there from LOG level
This makes it possible to easily get a *:5 debug log without all
the refcounting noise, and drastically reduces the number of lines
output for a normal log (46m to 28m for a 20min video). The full log
including refcounting information can still be gotten using *:7.

e5a13bd3fc gstcaps: Use inlined version of _is_any()/_is_empty()
CAPS_IS_ANY and CAPS_IS_EMPTY are the equivalent of their gst_caps_*
counterpart except that they avoid the typechecking and are inlined.

CAPS_IS_EMPTY_SIMPLE only checks for empty caps (without checking if
the caps is ANY).
