Adds a data order driven demuxer instead of trying
to rearrange seek order. Re-enables fragmented
files if fast-seekable.

So we can stop probing at some point.

Fixes the false positive and fallback on avcodec with
files having a mvex/trex but no fragments, and conforms
to the spec.

Avoid naming confusion, because data is an atom itself.

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.

PacketSize == nBlockAlign attribute of WaveFormatEx structure.

We also remove the AvgBytesPerSec attribute of the quality_level_t
structure, since it is equal to the Bitrate attribute (divided per 8).

This fixes streams done by Expression Encoder 4

also modify MP4_BoxGetNextChunk() so that a initialization
segment which has been put between two chunks is properly handled.

SmooBox is a very simple MP4 box, VLC specific, used only
for the Smooth Streaming module to send information to the demux.
SmooBox is actually a simplified moov box (we wanted to avoid
the hassle of building a moov box at the stream_filter level).

These are Smooth Streaming specific boxes, which provide duration and
time offset of subsequent(s) fragment(s), thus allowing us to avoid
manifest polling in "live" mode.

This is a DASH specific box. See [1] for its definition.
It will probably be useful in a near future, and I will use it at a
workaround to get fragment duration when tfhd and trun boxes don't give
(default) sample duration(s).

mfra atom contains two leaf atoms, 'tfra' and 'mfro'. The first one
provides file offsets of the chunks in a isml file.

mfra atom support will not help Smooth Streaming support in VLC (at
least for the client part), but can be useful for other
purposes, e.g. to enable VLC to play a "raw" isml file.

Atoms mvex, mehd, trex and sdtp are found at least in PIFF (isml) files.

This atom can store an optionnal aspect ratio.

The atom names are like FOURCC, but they are not fourcc
