server_attached is newly added so the demuxer knows if there is an attached server
that can update the write index. This is needed to fix a infinite loop

The ad-hoc pi constant has a ludicrous number of digits that offer no
value whatsoever. M_PI is more consistent and readable across the
codebase.

If videotoolbox_common_end_frame failed, then the AVFrame was returned
to the API user with the dummy buffer (in AVFrame.buf[0]) still set, and
the decode call indicating success.
These "half-set" AVFrames with dummy buffer are a videotoolbox specific
hack, because the decoder requires an allocated AVFrame for its internal
logic. Videotoolbox on the other hand allocates its frame itself
internally, and outputs it only on end_frame. At this point, the dummy
buffer is replaced with the real frame (unless decoding fails).
The replaced check should have become redundant

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.

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

In case of bitstream errors the deblock filter and slices can access uninitialized
top_borders from previous slices which did not fill them as they stoped halfway due
to error or where entirely missing.
This also makes code using these tables deterministic in case of missing or damaged
slices

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.

In the spirit of commit 8199908fdf9b3797cceaea9d1e2fc09d02ef7309, 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.
