Pass the correct size in bits to mpeg4audio_get_config and add a flag
to disable parsing of the sync extension when the size is not known.
Latm with AudioMuxVersion 0 does not specify the size of the audio
specific config. Data after the audio specific config can be
misinterpreted as sync extension resulting in random and wrong configs.
Manual replacements are done in this commit.
In many cases, the id is some constant made up number (e.g. 0 for video
and 1 for audio), which is then not used in the demuxer for anything.
Those ids are removed.
This avoids writing these entries doubly if transcoding from
flv to flv, since the muxer blindly writes any and all metadata
keys set, in addition to the fixed fields that the muxer
always writes.

On allocation, the array length is multiplied by sizeof(int64_t),
this prevents the multiplication from overflowing.

Stop the avio input at a point where amf_parse_object can
continue parsing the end of the object seamlessly, when all
data is available.
If unsupported data is encountered within the keyframes object,
try seeking to the start of the keyframes object - if the seek
back was successful, the caller can continue parsing the rest
of the AMF data.

Current keyframes data parser unconditionally rewind metadata to
the end at the end of function. As result ALL metadata located
after keyframes index not parsed, and as metadata object can have
ANY placement inside metadata it can lead to unpredictable result
(bitrate can not be found, etc.). As result FLV movie will not
play at all in such situation.

'keyframes' metatag is not part of the standard, it is just
convention to use such kind of metatag information for indexing.
Structure is following, it allows to have it inconsistent:
keyframes:
times (array):
time0 (num)
time1 (num)
time2 (num)
filepositions (array)
position0 (num)
position1 (num)

In the name of consistency:
get_byte -> avio_r8
get_<type> -> avio_r<type>
get_buffer -> avio_read
get_partial_buffer will be made private later
get_strz is left out becase I want to change it later to return
something useful.

av_metadata_set() is going to be dropped at the next major bump.

Implement flv_read_seek(), add a missing check on stream_index
and fix timestamp rounding in rtmp_read_seek().
Also add the flv_read_seek2() function, which is not enabled but is
useful as reference.
To actually implement flv_read_seek2() correctly, there would need to
be some corresponding av_url_read_fseek2() function to propagate the
timestamps down to the ByteIOContext and URLContext.

At the moment, duration is mainly set from the metadata packet. If that is not
available, the fallback is checking the low 24 bits of the last packet. This is
not enough for files over 4,6 hours in length, so read all 32 bits instead.

Do what the spec says, insane or not:
"
Format 0 (uncompressed) and Format 3 (uncompressed little-endian) are similar. Both encode
uncompressed audio samples. For 8-bit samples, the two formats are identical. For 16-bit
samples, the two formats differ in byte ordering. In Format 0, 16-bit samples are encoded and
decoded according to the native byte ordering of the platform on which the encoder and Flash
Player, respectively, are running. In Format 3, 16-bit samples are always encoded in little-endian
order (least significant byte first), and are byte-swapped if necessary in Flash Player before
playback. Format 0 is clearly disadvantageous because it introduces a playback platform
dependency. For 16-bit samples, Format 3 is highly preferable to Format 0 for SWF version 4
or later.
