8b4b1c1eea matroska: Support V_QUICKTIME as written in the specification 
Check if the size is written the first 4 bytes and read the next 4
as fourcc candidate, fallback checking the initial for 4 bytes.

"The CodecPrivate contains all additional data that is stored in the
'stsd' (sample description) atom in the QuickTime file after the
mandatory video descriptor structure (starting with the size and FourCC
fields)"

1389b4c18d idct8x8: Fix undefined negative shifts 
The original code left-shifts negative values, which is undefined
in the C99 specification (the one used during normal Libav compilation).
This change multiplies by (1 << shift), which is functionally equivalent,
but has defined behavior.

With this change, fate-idct8x8 compiled with --fsanitize=undefined works.

d40cb726d2 mov: Trim dref absolute path 
Samples produced by Omneon (Harmonic) store external references with
paths ending with 0s. Such movs cannot be loaded properly since every
0 is converted to '/', to keep the same parsing code for dref type 2
and type 18: this makes the external reference point to a non-existing
direactory, rather than to the actual referenced file.

Add a brief trimming loop that drops all ending 0s before trying to
parse the external reference path.

ff3db937ef asfenc: fix some possible integer overflows 
Store the file duration in the same timebase it arrives (i.e.
milliseconds) and only convert it to the file duration units (100ns)
when it's actually written, thus simplifying some calculations. Also,
store the duration as unsigned, since it cannot be negative.
