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.

This side data type is meant to be added to AVStream side data.
A fallback track indicates an alternate track to use when the
current track can not be decoded for some reason. e.g. no
decoder available for codec.

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.

FFv1 uses two types of coders, golomb and range with two different
tables. This is exposed this in a rather convoluted way, for example
mentioning to set coder type 1 while initializing the variable 'ac' to 2,
because encoder does not use range coder with default table.
Appropriate internal coder type values have been added and used in any
check rather than using raw numbers.
Initialization of avctx.coder_type in ffv1dec is removed because this
field is encoder only. An unneeded validation check in the encoder
is dropped too.

It is used as size argument of ff_canopus_parse_info_tag, which uses it
as size argument to bytestream2_init, which only supports sizes up to
INT_MAX.
Changing it's type to unsigned simplifies the check.

Small refactor of fps code for improved readability. In particular
the "cor" variable was unnecessary and misleading because it would
always be set to -delta0.
