The bswap16, bswap32 and bswap64 functions are already present on NetBSD
and cannot be redefined in include/vlc_common.h as this causes fatal build
errors.
Rename these functions to vlc_bswap16, vlc_bswap32 and vlc_bswap64 and
keep them as they are without fallback to the NetBSD's libc one. These
functions are already small enough and we can bear with them as duplicates
on the gain of no extra ifdefs in the vlc_common.h public header.

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).

Fixes endianness and aout 16/32 bits.
AOB channels are split into 2 groups, with only one
that might be in use. They both can differ in
resolution and sampling rate.
We have to set output buffer to max bits of those two
and adapt reads accordingly to each group.
We'll reject only different group sampling rates
(missing spec about interleaving).
This might suppress some warnings (and very slightly reduce code size)
when assertions are disabled. Not that I particularly like to create
VLC-specific macros.
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.
This patch adds encode support to the LPCM module; only the DVD variant for
now. It's not been tested with any other clients than VLC.
The rationale for this functionality is relatively simple -- LPCM is
currently the only low-latency codec that VLC supports and that can be
embedded in a TS stream. Longer-term support for other low-latency codecs
would be good, but if you're not particularly bandwidth-constrained and need
low latency, this is currently the best option I know of.

The format comments are out of sync with what the code actually
assumes. I updated the comments, and filled in some missing information from
http://www.mpucoder.com/DVD/ass-hdr.html .

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()...
