The fisbone packets can be muxed in any order as long the last one
comes before the first data packet.

Not having the header for a codec is a tell-tale of a broken file.

Additional safety in case a special ogg stream is crafted

The loop was introduced in 64d340c62ad5954c1a834df2d26057135e771774, and
was likely breaking non blocking reads as it busy loops.

This allows using avcodec_free_frame() to free it properly.

In particular, fix crash when the input file contains no packets (e.g. an
ffmeta input).

This is required in chained muxers, if the SAR happens to be set.

RTPDynamicProtocolHandler for speex is added. Initial support for
speex depacketization from RTP stream comes with it.
Currently, only codec audio rate can be applied based on sdp:
* Narrowband    ( 8K)
* Wideband      (16K)
* Ultrawideband (32K)

  when using rtp as output format.
* SDP rtpmap is added for speex payload, formatted according to RFC

Fix Ticket #1617, revealing a regression I introduced in 8f3eebd.

We need to make sure no stream is added in between Ogg context save and
restore operations (because it would likely lead to a mismatch between
ogg->nstreams and AVFormatContext->nb_streams after the restore op).
This is the reason the ogg->state check is added in ogg_new_stream().
Before this patch, checking for ogg->headers was preventing this:
ogg->headers is always set before any ogg save/restore (though, it was
also preventing from creating the stream when necessary).

This occurs with fuzzed mpeg-ts files. set_codec_from_probe_data() is
called with a zeroed AVProbeData since no packet made through for

Support Matroska native formatting.

On demuxing prepend a Frame container atom (32bit big endian encoded
frame size and 'icpf' string).
On muxing remove it.

Stricter validation, explicitly exit on misparsing and some error
forwarding from the ebml parsing functions used.

Make MATROSKA_TRACK_ENCODING_COMP_HEADERSTRIP behave like
the other encodings and spare few lines of boilerplate code.
