45a811b512 mov: fix composition timestamps on movie fragments. 
This fixes, for instance, the case that there is a track that has some samples with composition time offset and has a track run without sample-composition-time-offsets-present.

18b6a69ce9 Revert "VC1: merge idct8x8, coeff adjustments and put_pixels." 
This reverts commit f8bed30d8b. The reason
for this is that the overlap filter, which runs after IDCT, should run
on unclamped values, and thus IDCT and put_pixels() cannot be merged if
we want to attempt to be bitexact.

0bd433a916 asfdec: fix assert failure on invalid files 
Add an extra size validity check in asf_read_frame_header(). Without
this asf->packet_size_left may become negative, which triggers an
assertion failure later.

ad1862d64a ALPHA: Replace sized int_fast integer types with plain int/unsigned. 
int/unsigned is the natural memory access type for CPUs, using sized types
for temporary variables, counters and similar just increases code size and
can possibly cause a slowdown.

This works around a possibly exploitable crash.
Appearently, vlc can be exploited with a malicous file. This should get

7c152a458d lavf: inspect more frames for fps when container time base is coarse 
As per issue2629, most 23.976fps matroska H.264 files are incorrectly
detected as 24fps, as the matroska timestamps usually have only
millisecond precision.

Fix that by doubling the amount of timestamps inspected for frame rate
for streams that have coarse time base. This also fixes 29.970 detection
in matroska.
