third_party/ffmpeg: restart based on github upstream

This CL is based on a recent ToT from the github mirror of ffmpeg.
Previously, we had used Chromium's fork of github as our upstream,
modifying their gn build stuff a bit to make it work for fuchsia.
This wasn't really workable long-term, because the Chromium ffmpeg
rolls are extremely complex and involve 'make'ing a bunch of configs
we don't care about on multiple host machines.

The new approach is to use the github mirror of ffmpeg as our
upstream and to adapt Chromium's gn build stuff to work for us.
The result is something we can roll pretty easily using one linux
host.

The following files are adapted from Chromium:

	BUILD.gn
	README.fuchsia
	ffmpeg_options.gni
	fuchsia/patches/README
	fuchsia/scripts/...

These files are original ffmpeg source files that have been modified
to eliminate compiler warnings. Chromium does this as well:

	libavcodec/utils.c
	libavformat/utils.c

These files are generated by the 'roll' procedure:

	CREDITS.fuchsia
	ffmpeg_generated.gni
	fuchsia/config/...

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • ffserver is a multimedia streaming server for live broadcasts.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
