Do not declare *_sys_t typedefs globally in vlc_common.h. Instead,
declare them locally in each module that provides a definition.
This paves the way to move C++ definitions into anonymous namespaces in
order to respect C++ ODR.
The picture_resource_t and sout_stream_id_sys_t typedefs will be handled
separately, since they require specific additional changes.

Rename i_original_channels to i_chan_mode. For now, chan modes can be
DOLBYSTEREO or DUALMONO.
This new value, i_chan_mode, should only be set by demuxes/codecs/packetizers
if there is a special stereo mode to handle.
Use only one callback for every decoder types:
int (*pf_decode)(decoder_t *, block_t *p_block);
There is now only one way to send output frames/blocks from a decoder module:
using decoder_QueueVideo(), decoder_QueueAudio() and decoder_QueueSub()
functions.
This fixes transcoding not receiving any output when a decoder used
decoder_Queue*() function.
The pf_packetize callback is kept unchanged. A packetizer shouldn't be
asynchronous at all (and this simplify the locking for decoder core).
The pf_decode callback returns, for now, only one value: SUCCESS. This will
allow a module to send more status.
Decoder modules are now responsible for calling decoder_UpdateAudioFormat()
before decoder_NewAudioBuffer().
In a lot of modules, decoder_UpdateAudioFormat() could be called in a better
place. Just after dec->fmt_out is updated for example.
For now, a lot of decoder/packetizer are also flushing on
BLOCK_FLAG_DISCONTINUITY flag. Some others are also flushing on
BLOCK_FLAG_CORRUPTED flag (omxil, videotoolbox, avcodec audio).
This patch doesn't change the current behavior.
But maybe we shouldn't flush anymore on DISCONTINUOUS/CORRUPTED.
If blocks are marked BLOCK_FLAG_DISCONTINUITY then do not drop them,
unless BLOCK_FLAGS_CORRUPTED is set. Instead flush old blocks from decoder
queue and restart at this new stream access point (new timeline).

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.
As with Video-encoders, audio encoder can flush buffers in that case.
Currently avcodec doesn't handle flushing and other encoders in this
changeset (flac,speex,twolame,vorbis) have only boilerplate to check
against NULL input so they don't crash.
Changing the choice list of a configuration item is not thread-safe.
Plus it does not make much sense to use a strict choice list if the
choices change dynamically.
If ever needed, we can invent a suggestions list system later, just
like we already do for SD plugins enumeration.
It makes VLC compatible with FFmpeg vorbis/theora decoder.
It fixes support of big headers (like comments with an art encoded
as a base64 string...).
It simplifies a bit.
aout_buffer_t now looks very much like a subset of block_t at the
source code level. By the way, we might want to revisit the return value
of date_Increment()...
