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.
This is a queue which has the same API as GQueue, except that:
* It uses an array, instead of a doubled-linked-list
* The array can only grow.
This code is not-threadsafe. It is up to the owner to make sure the
proper locking is taken before calling this API.
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).

Postpone the #ifdef to a point after glib.h (via gstfdsink.h) is included
so that the needed defines and header includes can be done correctly,
especially on Visual C++ builds.

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().
Without using AC_INCLUDES_DEFAULT explicitly,
certain platforms will complain that the header
was found, but not usable by the compiler.
This happens for instance on Solaris where certain
headers are needed to pull in proper defines.
Also upgrade to newer autoconf syntax and use proper quoting.

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.
