gstreamer: Add Element::get_current_clock_time() and ::get_current_running_time()
...
This was added in GStreamer 1.18 but we can easily implement it
ourselves here for the time being and for older versions.

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

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.

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

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.
