ee5b369ffd gstvalue: make new gst_value_list_merge() work properly
Fix freeing of partially-inited list value when both values
passed are equal and we want to return a single non-list
value as result. Fixes unit test. Also fix up docs a bit.

gdatetime. Also move timezone parameter to the
first position, just like glib's.

8ca48752fb utils: Add gst_util_fraction_compare() to compare fractions

d41997040b gst: make _get_type() in gst/* thread safe
This is not really necessary here because everything is
initialized from gst_init() already but using G_DEFINE_TYPE()

a9d1a493a7 Fixes for -Wwrite-strings
This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.

Also adds -Wwrite-strings as a warning flag in configure.ac.

ec10b764b9 caps: Fail when fractions are followed by random text
Previous code treated "1/1yourmom" the same as "1/1" and "1wimsmom" the
same as "1". Now the code is stricter and will fail to convert a
fraction when followed by garbage text.

a5626f239a gstvalue: Use fast gst_value_list_{size|get_value} macro accessors
gst_value_list_size and gst_value_list_get_value will do a series of
extra checks due to being public methods.
When we use them from within gstvalue.c we can directly use them without
the extra checks.

gst_util_fraction_add()

Also add float<->fraction transform functions for GValue.

7bf3554228 structure: Change NULL and empty string handling
Don't forbid the empty string "" in generic structures, only in taglists.
Properly allow the NULL string by adding special cases for serialising
and deserialising it. prop1=(string)NULL is the NULL string,
prop1=(string)"NULL" is the actual string with the value "NULL"

923913984e Use local variables in for/while loops.
This makes the generated code faster since:
* It won't have to read an undirect value (which will most likely be
 outside of the L1/L2 cache)
* We know that value never changes (the compiler has no clue that it doesn't).

4530151ad2 gstvalue: more efficient value table lookup for fundamental types
Small micro-optimisation: look up value table for fundamental types
via an array dedicated to fundamental types instead of going through
a hash table lookup. Since there can be only 255 fundamental types,
the table size/efficiency trade-off should be acceptable, esp. since
the most commonly-used types are all fundamental types. The size of
the table could probably be minimised further if needed by allocating
the table dynamically and only expanding it on demand.

e8bfd88f26 gstvalue: don't put GTypes into int variables
GTypes are not ints and as such are not guaranteed to fit into an int
(with the exception of fundamental types), so we really shouldn't put
them into int variables. Even if a rather unlikely obscure corner case,
this has actually been a problem at some point in the past, see commit
99f16655f4.

766e7afc23 gststructure: Fix some memory leaks. Sprinkle G_LIKELY/UNLIKELY
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.

47d9904eba structure: fix serialisation of nested structures.
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.

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.

209c57085c gst/gststructure.c: No need to memset, we can clear the value ourselves.
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.
