71497e77de gstreamer/log: Allow any glib::Object as target for logging
gst::Object is not actually required. For plain glib::Objects only the
pointer address is printed instead of a name but it works fine.

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.

cddccf9502 gstreamer/promise: Add Future constructor for Promise
This returns a tuple that basically works like a oneshot channel: the
Promise acts as the "sender" and once the promise resolves the
"receiver" contains the result.

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.

7230aee069 Switch everything from lazy_static to once_cell::Lazy

in the standard library in a similar form to this.

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.
