baa0304074 avformat/utils: Fix undefined behavior in ff_configure_buffers_for_index() 
When e2_pts == INT64_MIN and e1_pts >= 0 the calculation of
e2_pts - e1_pts will overflow an int64_t.

keeping the condition in the if() simple.

debbbb5ba6 lafv/wavdec: Fail bext parsing on incomplete reads 
avio_read can successfully return even when less than the requested
amount of input was read. wavdec's bext parsing mistakenly assumed a
successful avio_read always read the full amount that was requested.
The result could be dictionary tags populated with partially
uninitialized values.

This change also fixes a broken assertion in wav_parse_bext_string that
was off-by-one, though no known current usage of that method hits that
broken case.

750ec96f66 avformat/mov: validate chunk_count vs stsc_data 
Bad content may contain stsc boxes with a first_chunk index that
exceeds stco.entries (chunk_count). This ammends the existing check to
include cases where chunk_count == 0. It also patches up the case
when stsc refers to unknown chunks, but stts has no samples (so we
can simply ignore stsc).

490a5253ca lavf/id3v2: fail read_apic on EOF reading mimetype

418f13261f lavf/mov: ensure only one tkhd per trak 
Chromium fuzzing produced a whacky file with extra tkhds. This caused
an AVStream that was already in use to be corrupted by assigning it a
new id, which blows up later in mov_read_trun because the
MOVFragmentStreamInfo.index_entry now points OOB.
