The NO_SHARE flag does not influence the exclusiveness of the buffer initially
but only if a _share operation can be done. Otherwise, we would not be able to
WRITE map a buffer memory because it would have a share count of at least 2.
We implement the locking in gst_memory_map with the lock flags, make matching
flags the same number so that we can use the map flags directly as lock flags.
Expose the internally used methods for locking and unlocking the object. Pass
the access mode to the unlock function for extra checks and because we need it
for the EXCLUSIVE locks.
Make some new defines to specify the desired locking.
Add a new EXCLUSIVE lock mode which will increment the shared counter. Objects
with a shared counter > 1 will not be lockable in WRITE mode.
Improve parallel installability in setups like jhbuild by
providing versioned variants of some environment variables:
GST_REGISTRY_1_0
GST_PLUGIN_PATH_1_0
GST_PLUGIN_SYSTEM_PATH_1_0
GST_PLUGIN_SCANNER_1_0
will now be checked before checking the unversioned ones.

We added a minimum length of three letters originally so we would
fail to recognise DOS/Windows-style filenames as valid URIs (as we
should). Two should be just fine as well.
Make GstSeekFlag to GstSegmentFlag conversion explicit, and
set only those seek flags in the segment flags which are
mapped. This makes sure we don't have extraneous flags
littering our segment flag field, which also fixes the
debug printing/serialisation of segment events in the
debug log.
Visual C++ does not have isnan(), so add fallback to
math-compat.h (could use _isnan() in this case, but
this makes it work for all cases where isnan is missing).

Make a gst_buffer_append_region() function that allows you to append a memory
region from one buffer to another. This is a more general version of
gst_buffer_append().
If we have a file called Foo\Bar.ogg, there is no way to pass
that filename properly to filesrc in gst_parse_launch(), since
gst_parse_unescape() will just unescape \x to x.
Not cherry-picking this into 0.10 since there are apparently
apps that work around this problem and which would break if
we fixed it there too.

Take into account that not all fields might be valid (though they
are valid in the GDateTime structure). But we should just return
unordered if the set fields don't match. Also, don't check
microseconds when comparing datetimes, since we don't serialise
those by default if they're available. This ensures date times are
still regarded as equal after serialising+deserialising.
Some tag parsers and writers use same datetime format based on ISO 8601.
We can reduce some code by creating some general functions for it.
API: gst_date_time_to_iso8601_string()
API: gst_date_time_new_from_iso8601_string()

Now that TOCs are refcounted and have a GType, we can just
stuff a ref of the TOC directly into the various toc
event/message/query structures and get rid of lots of
cracktastic GstStructure <-> GstToc serialisation and
deserialisation code. We lose some TOC sanity checking
in the process, but that should really be done when
it's being created anyway.
Let's keep it simple for now:
gst_toc_setter_reset_toc() -> gst_toc_setter_reset()
gst_toc_setter_get_toc_copy() -> removed
gst_toc_setter_get_toc() -> returns a ref now
gst_toc_setter_get_toc_entry_copy() -> removed,
use TOC functions instead
gst_toc_setter_get_toc_entry() -> removed,
use TOC functions instead
gst_toc_setter_add_toc_entry() -> removed,
to avoid problems with (refcount-dependent)
writability of TOC; use TOC functions instead
So mini objects don't have to poke into the GstMiniObject part
of the structure. Saves lines of code, and seems slightly cleaner.
We don't have proper OO hierarchies or methods here after all.
