This avoids setting a negative number of frames, ending up with a
negative average frame rate.

When av_reallocp fails, the associated variables that keep track of
the number of elements in the array (and in some cases, the
separate number of allocated elements) need to be reset.

Not all of these might technically be needed, but it's better to
reset them if in doubt, to make sure variables don't end up
conflicting.

Some files have the duration set to -1 in the mdhd atom, more
or less legitimately. (We produce such files ourselves, for the
initial duration in fragmented mp4 files.)

Fixes ticket #2864.

The time scale is set in mdhd, and later validated in the
enclosing trak atom once all of its children have been parsed.

A loose mdhd atom outside of a trak atom could update the time
scale of the last stream without any validation.

This fixes #2657.
ISML movies produced by Microsoft Expression Encoder 4 seem to have invalid
sample entries in their trun/tfhd for data tracks. As a result, too much bytes
are read for these tracks to the point that next_root_atom can go out of
buffer, which makes the encoding fail if the input is not seekable.

Some movies have negative composition time offsets in their trun, causing pts <
dts errors. This patch makes use of dts_shift to handle them.
