830695be36 avformat/movenc: read track title from correct key
da9cc22d5b allowed the MOV muxer to relay a custom stream handler name,
whether populated from the input stream or user-set. However, the entry
key didn't match the key set by the MOV demuxer, so it wasn't
effective. Fixed.

Due to the change, four FATE refs have to be updated. Verified that the
target payload of the tests hasn't changed in terms of CRC.

cd86c5dbcc avformat/mpegts: parse large PMTs with multiple tables
In 9152c1e495, the mpegts parser was taught how to parse
PMT sections which contained multiple tables. That commit
fixed parsing of PMT packets from some cable providers,
which included a special SCTE table (0xc0) before the
standard program map table (0x2).

Sometimes, however, the combined 0xc0 and 0x2 tables are
larger than a single TS packet (188 bytes). The mpegts parser
already attempts to parse sections which span multiple packets,
but still assumed that the split section only contained one
table.

This patch fixes parsing of such a sample[1].

Before:

    Input #0, mpegts, from 'combined-pmt-tids-split.ts':
      Duration: 00:00:01.26, start: 39188.931756, bitrate: 597 kb/s
      Program 1
      No Program
        Stream #0:0[0xeff]: Audio: ac3, 48000 Hz, mono, fltp, 64 kb/s
        Stream #0:1[0xefd]: Audio: mp3, 0 channels, fltp
        Stream #0:2[0xefe]: Unknown: none

After:

    Input #0, mpegts, from 'combined-pmt-tids-split.ts':
      Duration: 00:00:01.27, start: 39188.931756, bitrate: 589 kb/s
      Program 1
        Stream #0:0[0xefd]: Video: h264 ([27][0][0][0] / 0x001B), none, 59.94 fps, 59.94 tbr, 90k tbn, 180k tbc
        Stream #0:1[0xefe](eng): Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, stereo, fltp, 384 kb/s
        Stream #0:2[0xeff](spa): Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, mono, fltp, 64 kb/s
        Stream #0:3[0xf00]: Data: scte_35
        Stream #0:4[0xf01]: Unknown: none (ETV1 / 0x31565445)
        Stream #0:5[0xf02]: Unknown: none (ETV1 / 0x31565445)
        Stream #0:6[0xf03]: Unknown: none ([192][0][0][0] / 0x00C0)

With the patch, the PMT is parsed correctly so the streams are
created in the correct order, are associated with "Program 1",
and their codecs are set correctly.

318d0fcbfe lavf/mov.c: Fix timestamps to be strictly monotonic for video also.
We already do this for audio, but it should be done for video too.
If we don't, seeking back to the start of the file, for example, can
become quite broken, since the first N packets will have repeating
and nonmonotonic PTS, yet they need to be decoded even if they are
to be discarded.

While the documentation for this specific synchronous read

`if (handle->eof) { return 0; }`.

Right now segment file format is chosen to be either mp4 or webm based on the codec format.
This patch makes that choice configurable by the user, instead of being decided by the muxer.

Also with this change per-stream choice segment file format(based on codec type) is not possible.
All the output audio and video streams should be in the same file format.
