matroskaenc.c applies divisors to the display width/height when generating
stereo content. This patch adds the corresponding multipliers to matroskadec.c
so that the original sample aspect ratio can be recovered.

"Fast seek" uses linear interpolation to find the position of the
requested seek time. For CBR this is more direct than using the
mp3 TOC and bypassing the TOC avoids problems with TOC precision.
(see https://crbug.com/545914#c13)
For VBR, fast seek is not precise, so continue to prefer the TOC
when available (the lesser of two evils).
Also, some re-ordering of the logic in mp3_seek to simplify and
give usetoc=1 precedence over fastseek flag.

Fixes probing of truehd/mlp files with a lot of frames in between the
major sync frames. The spec allows a distance of up to 128 frames in
between major sync frames, which leads to the probing code not reaching
the desired score.
Avoid decoding a frame to get the codec parameters while the codec
supports FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM. This is particulary useful
to avoid decoding twice images (once in avformat_find_stream_info and
once when the actual decode is made).
If duration is still AV_NOPTS_VALUE when opening the next file, we can assume
that outpoint is not set.

The demuxer returned INVALIDDATA and failed to demux the remaining data
when an invalid stream index was read, now it just skips the asf packet
for the stream with an invalid stream index and continues demuxing.

Previously only the edit_rate of material_track was checked.
If it's negative, it causes assertion failures in av_rescale_rnd.

DASH manifest should have framerate specified as an attribute in the
AdaptationSet element and Representation elements. Though ISO/IEC
23009-1:2014 doesn't seem to define frameRate as a required attribute,
it is at least optional, and DASH-IF IOP 3.0 seems to require it. See
section 3.2.4 of http://dashif.org/w/2015/04/DASH-IF-IOP-v3.0.pdf
In the event that avg_frame_rate is not set in the muxer, we ignore the
frameRate tag altogther.

This feature allows making associations between audio tracks
that apple players recognize. E.g. when an ac3 track has a
tref that points to an aac track, devices that don't support
ac3 will automatically fall back to the aac track.
Apple used to *guess* these associations, but new products
(AppleTV 4) no longer guess and this association can only
be made explicitly now using the "fall" tref.

In the spirit of commit 8199908fdf, likely
typo originally.
Found by enabling -Wparentheses on clang 3.7 and running a manual audit.
To the best of my knowledge, no such instances remain.
