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.

This partially reverts 2f88dc6576

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.

This returns a tuple that basically works like a oneshot channel: the

fe4f074e90 bus: Don't use the bus sync handler in the bus Stream to notify about messages being available
This is racy and can cause the consumer of the messages to never be
woken up anymore:

1. Waker is stored because no message on the bus
2. Sync handler is called, waker is woken up
3. Bus is polled again and no message is on it (yet),
   new waker is registered
4. Bus stores the message from 2. in its queue (after
   the sync handler has returned BusSyncReply::Pass)
5. No new message ever appears on the bus because all
   this happened for the very last message

63a8afafa5 gstreamer: Use more accurate types for Seqnum, GroupId and MetaSeqnum
For the latter introduce an actual opaque type that allows using them
for comparison purposes but is not just a plain u64.

For the former represent them as opaque type around an NonZeroU32. 0 is
the invalid case and does not happen in the majority of functions. Where
it can happen, represent this case by using an Option<_> instead.

This makes it harder to mis-use these types.

d3c77f400d Don't derive Debug impls for generic types where the type parameters don't have to impl Debug themselves
This allows to use MappedBuffer and similar types to be properly
debug-printed.

Also change VideoFrame/VideoFrameRef/RTPBuffer from a tuple struct to a
struct with proper field names to make the code easier to understand.
