01da01c9e6 app: Handle panicking callbacks by converting into an error message

4e30798ac7 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.

ed80467ff6 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.

315a59e47d 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

3b56f470e5 Only allow setting Bus sync handler and AppSrc/Sink callbacks once 
Re-setting them is not thread-safe and can cause segfaults or worse.

462f4ac3b8 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.

9b593f626b gstreamer/promise: Add Future constructor for Promise 
This returns a tuple that basically works like a oneshot channel: the

"receiver" contains the result.

41663f15ef 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

5577e8a457 Don't derive Debug impls for generic types where the type parameters don't have to impl Debug themselves

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.

b127f93cb9 bus: Take the mutex before popping messages for the bus stream 
Otherwise a message might arrive between popping, getting None and

be woken up.

db1c341cdf gstreamer/element: Add call_async_future() that returns a future

      element.set_state(gst::State::Playing)
  }).await;

c29a7638d3 gstreamer: caps: BuilderFull: prevent adding features if using any 
Rework the API to statically prevent users adding extra features if the
builder has been created with builder_full_with_any_features(). It
doesn't make sense to add extra features if all are already included.
