9c01725e37 Simplify registration of RTP-header extensions.
Removes per-extension functions in ViEChannel/ViEReceiver and instead
register extensions directly on the RTP module by mapping extension
string to RTP-header-extension type.

db25d2e8c5 Make VideoTrack and VideoTrackRenderers implement rtc::VideoSourceInterface.
This patch tries to only change the interface to VideoTrack, with
minimal changes to the implementation. Some points worth noting:

VideoTrackRenderers should ultimately be deleted, but it is kept for
now since we need an object implementing webrtc::VideoRenderer, and
that shouldn't be VideoTrack.

This cl also remove the use of messages and posting of state change.
Further more - a thread checker is added to make sure methods are called on only one thread. Construction can happen on a separate thred.
It does not add restrictions on what thread frames are delivered on though.

There is more features in VideoCapturer::Onframe related to screen share in ARGB that probably can be cleaned up in a follow up cl.

This was already reviewed and landed in https://codereview.webrtc.org/1675923002/

4cc9f98e4c Fix bug 574524: DtlsTransportChannel crashes after SSL closes remotely
When remote side closes, opensslstreamadapter could return SR_EOS which will not trigger upper layer to clean up what's left in the StreamInterfaceChannel. The result of this is when there are more packets coming in, the Write on the StreamInterfaceChannel will overflow the buffer.

The fix here is that when receiving the remote side close signal, we also close the underneath StreamInterfaceChannel which will clean up the queue to prevent overflow.

58e08cbea8 Reset indexer upon initialization in AudioLoop.
The array is reset in Init() but not the indexer. This makes the start point undefined after Init() for re-initializing an AudioLoop. This can be fixed.

12f4cda086 Histograms for H264EncoderImpl/H264DecoderImpl
initialization and errors.

The stats are counts using enumeration, an instance of
H264EncoderImpl/H264DecoderImpl will report at most 1 Init
and 1 Error for its entire lifetime. This is to avoid
spamming reports if initialization or coding fails and it
retries in a loop. The Init stats will give us an idea of
usage counts for the encoder/decoder. The Error stats will
give us an idea of how many of these usages encounters some
type of problem, such as encode or decode errors.

- WebRTC.Video.H264EncoderImpl.Event:
  * kH264EncoderEventInit: Occurs at InitEncode.
  * kH264EncoderEventError: Occurs if any type of error
    occurs during initialization or encoding.
- WebRTC.Video.H264DecoderImpl.Event:
  * kH264DecoderEventInit: Occurs at InitDecode.
  * kH264DecoderEventError: Occurs if any type of error
    occurs during initialization, AVGetBuffer2 or decoding.

b7261fd3ae iSAC float: Check for end of input buffer while decoding
Previously, we relied on the encoded stream to come to an end before
the end of the buffer. This is a bad idea, since it is possible to
craft a stream that fills the buffer while decoding to less than the
expected amount of data; without the new checks introduced here, this
causes the decoder to read past the end of the input buffer.

b01c7816a8 Added functional variants of Buffer::SetData and Buffer::AppendData.
They are invoked with the maximum size of the data to be added, and a
callable that generates that data, like this:

buffer.AppendData(10, [] (rtc::ArrayView<uint8_t> av) {
    for (uint8_t i = 0; i != 5; ++i)
      av[i] = i;

    return 5;
  });

The callable returns the number of bytes actually written, and the
final Buffer size will be adjusted accordingly. SetData and AppendData
both return the number of bytes added (i.e. the return value of the
callable).

These versions will be useful when converting AudioEncoder::Encode to use Buffer rather than raw pointers.

Also added a few tests for the new functionality.
