314a2b961a caps: Hide implementation details
Make the Array of structures private. This should allow us to implement
the array more efficiently or with some preallocated structures when
we want to later.
Add a new method to clean up a static structure so that we can remove some code
that pokes into the private bits of the caps.

57df188757 caps: Add gst_caps_is_subset_structure()
API: gst_caps_is_subset_structure()

This allows to check if a structure is a subset of given
caps without allocating a new caps instance for it.

d98e9acb0f caps: Optimize gst_caps_is_subset()
..and as a result gst_caps_is_equal() and others.

This now only checks if for every subset structure there is
a superset structure in the superset caps. Previously we were
subtracting one from another, creating completely new caps
and then even simplified them.

The new implemention now is about 1.27 times faster and doesn't
break the -base unit tests are anything anymore.

0cf2dfd0ba caps: Fix subset check in gst_caps_merge()
Caps A are a subset of caps B even if caps B doesn't
have all fields of caps A.

Also add a unit test for this.

d706ca0859 Revert "caps: Optimize gst_caps_is_subset()"
This reverts commit 32248a9b85.

This breaks some tests in -base and the failures should
be fixed first.

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.

Just like gst_caps_intersect, but adds a new parameter 'mode'

GST_CAPS_INTERSECT_MODE_FIRST.

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.

Pipeline serialisation to and from XML is horribly broken for all

Make sure everyone playing around with these tools is aware of
this, to avoid frustration. See countless bug reports in bugzilla.
