Subtract the calculated dts offset from the requested timestamp before
seeking. This fixes an error "Error while filtering: Operation not
permitted" observed with a short file which contains only one key frame
and starts with negative timestamps.
Then, av_index_search_timestamp() returns a valid negative timestamp,
but mov_seek_stream bails out with AVERROR_INVALIDDATA.
Fixes ticket #6139.

If the metadata packet is corrupted, flv_read_metabody can accidentally
read past the start of the next packet. If the start of the next packet
had been flushed out of the IO buffer, we would be unable to seek to
the right position (on a nonseekable stream).
Prefer to clearly error out instead of silently trying to read from a
desynced stream which will only be interpreted as garbage.
According to EBU tech 3285 supplement 3 the dwPosPeakOfPeaks field
should contain the absolute position to the maximum audio sample value,
but the current implementation writes the relative peak frame index
instead.
Fix the issue by writing the "unknown" value (-1) for now until the
feature is implemented correctly.

When keyframe intervals of dash segments are not perfectly aligned,
fragments in the stream can overlap in time. The previous sorting by
timestamp causes packets to be read out of decode order and results
in decode errors.
Insert new "trun" index entries into index_entries in the order that
the trun are referenced by the sidx.

Add comments to describe the sources of the constraint values expressed here,
and add some more related values which will be used in following patches.
Fix the incorrect values for SPS and PPS count (they are not the same as those
used for H.264), and remove HEVC_MAX_CU_SIZE because it is not used anywhere.
