sps id can obviously never be negative

Boxes/atoms functions are unrelated to bitstreams.

New profiles that might break packetization.
(ITU-T H264 2014/02)

Old profile, out of spec
ref: https://ffmpeg.org/pipermail/ffmpeg-devel/2012-October/132400.html

new sample:
samples/V-codecs/h264/lossless_timecode_HIGH444_IDC144.h264

chroma/scaling/matrix is on HIGH profile SPS
(as in 14496-10:2012)

Don't end the NAL unit when we reach 0x000000. Refactor since we don't need to
parse separately the start and the end of the NAL unit anymore.

This function converts Annex B to avcC format.

cf. ISO/IEC 14496-15 5.2.4.1

SPS and PPS NAL units always start with 0x00000001 and finish with 0x000000,
0x000001 or the end of the bytestream.

The goal is to expose h264_parse_sps and h264_parse_pps functions that can be
used from decoders.

It fetches the SPS and PPS pointers from an Annex B buffer.

This is necessary in order to pass one single H264 packet in
multiple OMX buffers to the decoder.

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.

Cool hints:
 - If your header doesn't match "Lesser" 3 times, you are not good
 - If you use LGPLv2, you are not good
 - If you use the old FSF address, you are not good
