urlprotocol: receive a list of protocols from the caller
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
These macros were added in OS X 10.11, and the file compiles without warnings
on both 10.10 and 10.11 with them removed.
Thanks to mark4o on IRC for pointing out the failure and testing the patch.
Every date parsing routine now uses av_parse_time which handles 'now' and
provides greater precision as well. This change also enables the segmenter
muxer to set the proper 'now' creation time at the beginning of each segment.

This can be used for formats which write all format metadata as string to
files, therefore non-standard creation times such as 'now' will be parsed.
The standardized creation time is UTC ISO 8601 with microsecond precision.

It makes no sense whatsoever to do this at each function call; we
already have a table for this.

and more importantly a non-negligible speedup (~ 8%) to overall AAC encoding:
old:
ffmpeg -i sin.flac -acodec aac -strict -2 -y sin_new.aac 6.82s user 0.03s system 104% cpu 6.565 total
new:
ffmpeg -i sin.flac -acodec aac -strict -2 -y sin_old.aac 6.24s user 0.03s system 104% cpu 5.993 total
This also improves accuracy of the expression by ~ 2 ulp in some cases.

This fixes a data race warning by ThreadSanitizer.
FrameThreadContext.die is read by all the worker threads but is not
protected by any mutex. Move it to PerThreadContext so that each worker
thread reads its own copy of |die|, which can then be protected with
PerThreadContext.mutex.

This was a regression introduced by commit e7345abe05 which
enabled full use of the allocated packet but due to the overhead of
using field coding the buffer was too small and triggered warnings and
crashes.

The fact that now all quantization indices costs are cached justifies
storing 20 more integers in a structure already allocated on heap.

Add some more verbose info regarding why the imprecise and slow floor(x+0.5) hack
is used; helpful for future maintenance.

This commit also disables the async fate test, because it
