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).

08c56edb84 docs: Modify docs string slightly.
Apparently starting the last line of a docs string with 'returns' both
confuses and enrages gtk-doc. Use a slightly different wording instead.

0ff4086507 Improve caps setters API
This patch adds gst_caps_set_value() and allows gst_caps_set_simple() to
work on non-simple caps. See the API documentation for the functions
about what they do.

The intention of these changes is to ease working with caps in caps
transform functions. An example for this would be ffmpegcolorspace,
where the caps transform function could be changed to look roughly like
this (pseudocode ahead):
  result = gst_caps_copy (template_caps);
  value = gst_structure_get_value (gst_caps_get_structure (caps, 0),
    "widh");
  gst_caps_set_value (result, value);
  /* same for height, framerate and par */
  return caps;
which is much cleaner and easier to understand than the current code.

568202cb47 caps: add gst_caps_can_intersect()
Often we don't need the result of the intersection. Add a variant that only
tries to intersect. It can break out earlier and does less GValue copying.

baaf7e5319 caps: split callback for structure intersect into two functions
We call this separately. there is no much benefit in reusing the callback.
Splitting is let us remove a branch also.

18aeb9a41e gst/gstcaps.c: Callgrind micro optimisations.
Original commit message from CVS:
* gst/gstcaps.c: (gst_caps_copy), (_gst_caps_free),
(gst_caps_merge_structure), (gst_caps_get_structure),
(gst_caps_copy_nth), (gst_caps_set_simple),
(gst_caps_set_simple_valist), (gst_caps_is_fixed),
(gst_caps_is_equal_fixed), (gst_caps_intersect),
(gst_caps_subtract), (gst_caps_normalize), (gst_caps_do_simplify),
(gst_caps_to_string):
Callgrind micro optimisations.
Avoid array bounds checks and force inline of trivial function.
* gst/gstobject.c: (gst_object_set_name_default):
-1 is equivalent to letting glib to the strlen but then there is more
room for optimisations and it's not our fault.
* gst/gststructure.c: (gst_structure_id_empty_new_with_size):
no need to clear the array, we're cool.
* gst/gstvalue.c: (gst_type_is_fixed), (gst_value_is_fixed):
The most common _is_fixed() check is done on fundamental glib base
types so we check this first instead of doing a huge amount of
useless GST_TYPE_ARRAY calls.

multiple reallocs on the way); also use g_string_sized_new() in
various places with an approximate string length to avoid reallocs
within GString. See #500143.

Changed gst_structure_to_string to print ';' in the end.
Changed gst_caps_to_string to not print ';' beteween its
fields (structures) anymore and remove the lastes ';' from latest
structure. Now it is possible to have nested structures.
In addition, backward compatibilty is assured by accepting '\0' as
end delimiter. Fixes: #487969.
