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.

There can be only one track reference. The multiple tref handling is
handled at a different level.

This was broken in 0d96ec19eb under the

The sample in https://bugzilla.libav.org/show_bug.cgi?id=393 and
samples/F4V/H263_NM_f.mp4 both have codec_tag H263 for different
codecs. H263 is apparently used by Flash Media Server for Sorensen
Spark videos.

Patch based on commit 5442083b1c by
Carl Eugen Hoyos. Fixes bug 393.

These tags describe the product and quicktime library version respectively.
Originate from Adobe Premier, but some other products use them.

Avoids a 2G memory allocation and parsing of random data in
mov_read_dref(). The fuzzed sample sample.mp4_s224424 triggers this.

Fixes an assert in fuzzed sample sample.mp4_s265930.
