(gst_caps_switch_structures): New static function, switches out
structures inside a caps, taking care of parent_refcount setting.
* gst/gstpad.c (gst_pad_get_allowed_caps): Remove the restriction
on only src pads, wim von masterhack claims it was bogus.
* testsuite/caps/Makefile.am

done a bit differently in THREADED.

testsuite/caps/value_serialize.c: merge from HEAD.
Original commit message from CVS:

* testsuite/caps/value_serialize.c: merge from HEAD.

* testsuite/caps/filtercaps.c:
* testsuite/caps/enumcaps.c:
* testsuite/caps/deserialize.c:

* testsuite/caps/audioscale.c: Unref caps, not free.

implementation for identity.
* gst/gststructure.h

(gst_caps_structure_fixate_field_nearest_double):
(gst_caps_structure_fixate_field_nearest_int): Moved from
gstcaps.c because we need the private IS_MUTABLE macro.
(IS_MUTABLE): New macro, determines if a
structure is mutable or not.
(gst_structure_free): Don't allow free while holding a pointer to
a parent's refcount.
(gst_structure_set_name): Check for writability.
(gst_structure_id_set_value): Same.
(gst_structure_set_value): Same.
(gst_structure_set_valist): Same.
(gst_structure_remove_field): Same.
(gst_structure_remove_all_fields): Same.
(gst_structure_map_in_place): New routine, like _foreach but
allows the function to mutate the value (via a non-const
prototype). Check for writability.
(gst_structure_foreach): Redefine to only take non-mutating
functions.
* gst/gstcaps.c (IS_WRITABLE): New macro, returns TRUE if the caps
are writable.
(gst_caps_copy): Add some docs about mutability, etc.
(_gst_caps_free): Set the parent refcount pointer on structures to
NULL before freeing them.
(gst_caps_ref): Document.
(gst_caps_make_writable): Doc.
(gst_caps_make_writable): Changed to make_writable, get_writable
sounds too much like retrieving a property.
(gst_caps_copy_1): Removed, not very useful.
(gst_caps_ref_by_count): Removed, no need to have something GLib
doesn't.
(gst_caps_copy_conditional): Ref instead of copying.
(gst_static_caps_get): Retain a reference to the returned caps, so
that the static caps will remain immutable.
(gst_caps_remove_and_get_structure): Set the parent refcount to
NULL when removing the structure.
(gst_caps_append): Fix to work with structure parent refcounts.
Check for writability.
