Add a GType->GstValueTable hashtable mapping.
Avoid _get_type() multiple times when we can.
Use GSlice for fraction range dynamic memory
Add G_LIKELY when we can
Improve lookup of the value table using the hashtable
Fix some memory leaks shown by the new serialisation/deserialisation unit
test. Split the gst_string_wrap function in gstvalue.c into components and
use them to make gst_string_take_and_wrap, which takes ownership of the
string, avoiding a strdup.
Add some G_LIKELY/UNLIKELY, and clean up some leaks in error paths.
Use string_warp/unwrap to escape delimiters, otherwise deserialisation fails.
Also move GST_ASCII_IS_STRING to private header to avoid keeping it in sync.
Also use '\0' when terminating a string for better readability.
Original commit message from CVS:
* gst/gstvalue.c: (gst_type_is_fixed), (gst_value_is_fixed):
Reorganize some more, be more conservative with the GST_TYPE_ARRAY not
being fixed and inline the trivial check.
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_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.
Original commit message from CVS:
* gst/gststructure.c: (gst_structure_id_empty_new_with_size):
No need to memset, we can clear the value ourselves.
* gst/gstvalue.c: (gst_type_is_fixed),
(gst_value_get_compare_func):
Some optimisations from a few callgrind sessions:
When checking if a type is fixed, check for trivial fundamental types
first before checking types for which we need to get the type followed
by the heavy duty type checks, this reduces the amount of
g_type_fundamental() calls a lot.
When getting the compare function, first check for our registered types.
If that fails, do the heavy duty g_type_is_a() checks, reduces the
amount of g_type_is_a() considerably.

object type in addition to its name.

Optimisation: bail out of the loop as early as possible (#500143).

* gst/gstvalue.c:

exported for some reason (they were never in any header files
though).

* tests/check/gst/gstvalue.c: (GST_START_TEST):
Added GstStructure to gst_value_table and its related functions.
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.
API: add gst_value_set_structure()
API: add gst_value_get_structure()
