ea3672b7d6 avformat: add url field to AVFormatContext
This will replace the 1024 character limited filename field. Compatiblity for
output contexts are provided by copying filename field to URL if URL is unset
and by providing an internal function for muxers to set both url and filename
at once.

2cbe6bac03 avfilter/vf_framerate: change blend factor precision
This is done mainly in preparation for the SIMD patches.

- for the 8-bit input, decrease the blend factor precision to 7-bit.
- for the 16-bit input, increase the blend factor precision to 15-bit.
- make sure the blend functions are not called with 0 or maximum blending
  factors, because we don't want the signed factor integers to overflow.

Fate test changes are due to different rounding.

32bc4e77f6 avcodec/nvenc: unregister input resource when unmapping
Currently the resource is only ever unregistered when the
registered_frames array is fully in use and an unmapped entry is re-used
and cleaned up.
I'm pretty sure the frame will have been cleaned up before that happens,
so I'm kinda surprised this never blew up.

23ffeb91fe hls: don't print a certain warning if playlist loading is aborted
AVERROR_EXIT happens when the user's interrupt callback signals that
playback should be aborted. In this case, the demuxer shouldn't print a
warning, as it's expected that all network accesses are stopped.

6194d7e564 avformat, hls: add a flag to signal unavailability of seeking
The seek function can just return an error if seeking is unavailable,
but often this is too late. Add a flag that signals that the stream is
unseekable, and use it in HLS.

637dfa3942 hls: do not allow fallback to generic seeking
This makes little sense due to how HLS works, and only causes some
additional annoyances if the HLS read_seek function fails (for example
if it's a live stream). It was most likely unintended.

18e2ac032e avformat/dashenc: Signal http end of chunk(http_shutdown) explicitly

This mean playlists http writes would have to wait upto a segment duration to signal end of chunk causing delays.
This patch will fix that problem and improve performance.

74cf4a75f7 ffmpeg: Ignore SIGPIPE
On systems which deliver SIGPIPE (Unices), a broken pipe will currently
result in the immediate termination of the ffmpeg process (the default
disposition as required by POSIX).  This is undesirable, because while
the broken pipe is likely fatal to useful cleanup of whatever component
is writing to it, there might be other components which can do useful
cleanup - for example, a muxer on another stream may still need to write
indexes to complete a file.  Therefore, set the signal disposition for
SIGPIPE to ignore the signal - the call which caused the signal will
fail with EPIPE and the error will be propagated upwards like any other
I/O failure on a single stream.

8a4cc0a256 avformat: add option to parse/store ID3 PRIV tags in metadata.
Enables getting access to ID3 PRIV tags from the command-line or metadata API
when demuxing. The PRIV owner is stored as the metadata key prepended with
"id3v2_priv.", and the data is stored as the metadata value. As PRIV tags may
contain arbitrary data, non-printable characters, including NULL bytes, are
escaped as \xXX.

Similarly, any metadata tags that begin with "id3v2_priv." are inserted as ID3
PRIV tags into the output (assuming the format supports ID3). \xXX sequences in
the value are un-escaped to their byte value.
