4ad101b53b Use once_cell crate directly again 
The glib crate does not depend on it anymore and also does not re-export
it anymore.

Also switch some usages of OnceCell to OnceLock from std.

39155ef81c ndisrc: Implement zerocopy handling for the received frames if possible 
Also move processing from the capture thread to the streaming thread.
The NDI SDK can cause frame drops if not reading fast enough from it.

All frame processing is now handled inside the ndisrcdemux.

Also use a buffer pool for video if copying is necessary.

Additionally, make sure to use different stream ids in the stream-start
event for the audio and video pad.

This plugin now requires GStreamer 1.16 or newer.

022afa6375 ndi: use v210 encoding for cc and attach to video frame 
The NDI closed captions specifications [1] define a variation where metadata is
attached to the video frame. This requires the AFD buffer to be v210 encoded.
This commit applies this strategy.

Another difference with previous version is that when an error occurs while
encoding or decoding a meta, next meta are also tried instead of failing
immediately.

Receiving closed captions as a standalone metadata is kept for interoperability
purposes. In this case, metadata is also expected to be v210 encoded.

9604dea90a net/ndi: add closed caption support 
Closed caption support in NDI is described as a proposal in [1] & [2].

The proposal consists in encapsulating c608 or c708 closed caption in ADF
packets and pushing them in an XML tag as part of NDI Metadata.

This commit implements this proposal.

9c10ba87df ndisrc: Improve handling of broken sources with regards to timestamping 
- NDI HX Camera Android in the past used 1ns instead of 100ns as unit
   for timecodes/timestamps.
 - NDI HX Camera iOS uses 0 for all timecodes and the same non-zero
   value for all audio timestamps

Detect such situations and try to compensate for them. Also add a new
"auto" timestamping mode that prefers to use timecodes and otherwise
falls back to timestamps or receive times.
