Move the assignation of p_enc->p_sys to the end of the function to
ensure it will never be set on error. There's currently no error
happening between both code location. No functional changes.
We don't need to know it's a pointer and can save 2 characters.
No functional changes. This is simply renaming "dec->p_fmt_in",
"decoder->p_fmt_in", "dec.p_fmt_in" and "packetizer->p_fmt_in"
see e967f81f6a.
note, this does **not** affect cat-based module selection items
(of which there are just three in use by the core), since that
mechanism uses subcats not cats.
Currently, when encoding an ES category, the encoders had to check
whether they supported the ES category and return an error, forcing many
modules to be loaded and probed for nothing.
By splitting by ES category, we ensure that most encoder that would have
not supported the encoding anyway won't be probed. As a side effect, it
improves the documentation in the help output by only listing encoders
that will actually be able to encode the format, for instance in
aenc/venc/senc options in the transcode module. It will also provide a
better way for the UI to list the available encoders.
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.

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.
