Re-license almost all the playback modules to LGPLv2.1+ with
authorization from their respective contributors (230+)

This includes:
 - access, codec, packetizers, demux
 - audio filters, audio mixers, audio output
 - video filters, video chroma, video output
 - text renderers
 - XML parser
 - ARM NEON and SSE2 optimisations (mostly for chromas and filters)

Some modules are not concerned:
 - BDA and DShow access modules because Manol Manolov is AWOL
 - Real RTSP, because it is derived from Xine
 - x264 and t140 because they are encoders only
 - DLL Loader, because it is derived from MPlayer
 - DTS packetizer, because Jon Lech Johansen is AWOL
 - Shine and WMAfixed, because they are derived from Rockbox
 - Real demuxer, as it is derived from MPlayer and Wang Bo is AWOL
 - MPC demuxer, as Yavor Doganov is AWOL
 - Tivo demuxer, because it is derived from an MPlayer fork
 - Playlist demuxer, (WPL and ZPL parts missing), because suheaven is AWOL
 - iOS audio output and video display, because author refuses the license change
 - Equalizer and compressor, because Ronald Wright is AWOL
 - Mono, Headphone and Dolby, because author refuses the license change
 - hqdn3d and yadif, because they are from MPlayer/libavfilter
 - remoteosd, because it derives from RealVNC code
 - MMX optimisations, because Ollie Lho, from SiS, is AWOL
 - Rotate, because it depends on GPL motion

Nota Bene:
 - Some modules depend on GPL-only libraries, a LGPL module does not mean
   that the resulting binary module will be LGPL.
   Libraries affected would include liba52, libdvdcss, libdvdnav, libdvdread,
   faad2, libdca, libmad, libmpeg2, libpostproc, SRC, sid, zvbi and probably others.

The acceleration plugin now returns the expected pixel format instead
of checking it. That way, the avcodec module can check it directly.

This works as long as each acceleration plugin supports only one pixel
format (otherwise a table would be required).

vlc_xlib_init() already checks for --no-xlib internally.

Our custom codec names table lacked boundary checks and was incomplete.

libavutil.h doesnt include common.h since lavu 51.39.

Obsolete "ffmpeg" prefix
Use "avformat" or "avcodec" prefix
avio has no options (yet)
switcher uses "sout-switcher" prefix
Use "sout-avformat" for muxer

The field was renamed in lavc54 and setting values changed from
enum to bitfield.
We don't need to care about this because VLC doesn't specify values.

Revert this when you have found the reason why it fails for soo many
people, in avi, mp4 (and mkv before the HACK)

It workarounds an avcodec issue.

It should fix #5753.
There can still be an issue with an insufficient input caching.

This reverts commit 8b914fcd.

The problem was fixed in bc3b85c6.

This reverts commit 3c6bb18e.

Revert "avcodec: fix direct rendering with some codecs"

This reverts commit fcc84608.

The issue is not related to EMU_EDGE flag

as documented by doc/APIchanges

Provide edge buffers when CODEC_FLAG_EMU_EDGE is set
Fix ProRes playback with direct rendering

Crashes in the SSSE3 asm

Define _WIN32_WINNT to 0x600 when checking/using dxva2 headers
Continue to use a lower version to retain XP compatibility for the rest of VLC

The global one may not be in synch when the callback is called.

fffmpeg -> ffmpeg

It seems that the global one is not in synch when the callback is called.
When MT was in use, non I420 streams were broken.
