70d1f1f177 gstcaps: Make sure _normalize() is applied on all structures.
We need to use gst_caps_get_size() in the loop counter since some
structures could be added while iterating.

71f3a6f0f7 Don't include <libxml/parser.h> from public headers if GST_DISABLE_DEPRECATED is defined
Since everything GstXML related has been deprecated, we can now skip the
libxml includes from the public headers when GST_DISABLE_DEPRECATED is
defined.

See #463435.

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.

Fixes bug #622685.

32adac81ee gstcaps: New gst_caps_steal_structure() method
This allows removing structures from caps without them being freed. Helpful when
plugins need to move around structures without having to do an expensive structure
copy.

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).

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.

18aeb9a41e gst/gstcaps.c: Callgrind micro optimisations.

(gst_caps_copy_nth), (gst_caps_set_simple),

(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.

In addition, backward compatibilty is assured by accepting '\0' as
end delimiter. Fixes: #487969.
