  replace internal ffmpeg headers with BitReader

This should have no functional change.

References https://github.com/MythTV/mythtv/issues/428

The hack is no longer necessary since internal FFmpeg headers are no longer
included by the parsers.

avformatdecoder.cpp needed the public FFmpeg header "libavutil/intreadwrite.h".

This reverts commit 9632275126d4e6a698569c9d4316a300fe98d18f.

I agree with stuartm’s decade old comment on MythTV ticket 3001: H.263 is not a commonly used codec and if these are still bugs, they should be (re-)opened upstream with FFmpeg.

For frame rate “fix” see: October 2005
Closes #509, by applying patch. https://github.com/MythTV/mythtv/commit/f851316ffc438d3570ee47ab87d4ad961d36bb4e

  lavf: export flush_packet_queue() as mythtv_flush_packet_queue()

FFmpeg 5.0 renames and exports this as ff_flush_packet_queue().

This change is intended to make transitioning to FFmpeg 5.0 easier.

Technically, this should be in libavformat/internal.h, but, since it is currently
unmodified, libavformat/avformat.h will work for now.  (MythTV does not directly use
this function.)

No functional change, but AVStream.codec was removed in FFmpeg 5.0.

This should enable it to compile with FFmpeg 5.0, since it will then be
not compiled.

This replaces the use of the MythTV added, exported PMT for detecting
these in AvFormatDecoder::GetAudioTrackType().

disposition is copied over to the AVStream in mpegts_add_stream().

language is only 4 bytes, so don't write past the end.
i.e. the loop is invalid.
