a884a419db gstreamer/buffer: Add a BufferCursor / BufferCursorRef helper structs 
This implements Read/Seek or Write/Seek and allows to read/write/seek
into the buffer without merging the memories inside.

The writer also only maps the memory write-only as compared to all other
ways of accessing the buffer/memory data in a writable way, which have
to map it read-write.

See https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/425
for a similar API proposal for GStreamer core.

b21f576430 Add #[must_use] attribute to mutex guards / stream lock 
It's usually a mistake if creating one of these and immediately dropping
them again as that would immediately unlock the mutex again.

98ecef7153 Make sure to hold MutexGuard for the remainder of the function in various places 
Not assigning it to a variable would cause it to be dropped immediately
and the lock to be released again immediately.

50234bb5e6 pbutils: encoding_profile: remove get_restriction() from Container API 
Same rationale as the preceding commit, restriction isn't meant to be
used with container profiles.

745aee629b pbutils: encoding_profile: remove restriction setters from Container API 
As stated in the GstEncodingProfile documentation, restrictions are not
meant to be used for container profiles. So remove the APIs allowing to
set one when building and to change it later on.

d58cf01e3a Allow changing bus sync handler and appsink/src callbacks when running with 1.16.3 or newer 
Previously it was not thread-safe to change them and could lead to
crashes but with 1.16.3 it is now.

Unsetting the bus sync handler before 1.16.3 will have no effect at all,
setting a new bus sync handler or appsink/src callbacks will panic.

a2a1a87c46 video/video-info: Don't use bool return of gst_video_info_set_format()/align() when running with GStreamer < 1.11.1 
The bool return value was added in 1.11.1 and using the return value
with older versions gives a random value that might be true or false,
and then causes spurious errors.
