1679f23beb avcodec/dstdec: Replace AC overread check by sample rate check
Real files do skip coding 0 bits at the end, thus this kind of check
does not work reliable.

Fixes: Ticket 8770
Fixes: dst-256fs44-6ch-refdstencoder.dff

The samplerate is specified in ISO/IEC 14496-3:2005(E) as one of 3 fixed
values, this also can be used to limit the duration and avoid the timeout

This reverts commit f6df99dba1.

14f919515d avcodec/mlpenc: remove delay codec capability
The encoder has no delayed packets at the end of the encoding
process, so signaling this capability is unnecessary.

This also fixes an assertion failure introduced in 827d6fe73d, as

579ac96a04 libavcodec/jpeg2000.c: Precinct size check removed
This patch removes a check which throws an error if
the log2 precinct width/height is 0. The standard allows
the first component to have 0 as the log2 width/height.
However, to ensure proper intialization of coding style,
an extra check has been added.

60d79b1df9 lavc/aac_ac3_parser: improve the raw AAC file bit rate calculation
Now we just use one ADTS raw frame to calculate the bit rate, it's
lead to a larger error when get the duration from bit rate, the
improvement cumulate Nth ADTS frames to get the average bit rate.

e,g used the command get the duration like:
ffprobe -show_entries format=duration -i fate-suite/aac/foo.aac

before this improvement dump the duration=2.173935
after this improvement  dump the duration=1.979267

in fact, the real duration can be get by command like:
ffmpeg -i fate-suite/aac/foo.aac -f null /dev/null with time=00:00:01.97

Also update the fate-adtstoasc_ticket3715.

55c7bb0665 avcodec/nellymoserdec: Don't use invalid AVPacketSideDataType
Commits 957a593cd9 and
11828b8885 made the flv demuxer export
a certain flag as side data to be used by the nellymoser decoder for
mid-stream sample rate changes. It used a custom side data type 'F' that
was never officially documented.

Yet since 2215c39e94 (merged in commit
52c522c720) this information is exported
via the properly documented AV_PKT_DATA_PARAM_CHANGE side data.
The merge commit therefore stopped exporting the 'F' sidedata; yet the
changes in the Nellymoser decoder (which are now dead code (and would
become dangerous if lots of new side data types were added)) have not
been removed. This commit does this.
