This separates the region type from its container.
The drawback is that it makes the structure bigger. But we get plenty
of helpers. There might be other containers suitable but we use a mix of
append and prepend.
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"
av_init_packet is deprecated in new major version of ffmpeg.
Also use av_packet_free instead of unref.
Use av_packet_clone and AVPacket * in vlc_av_packet_t.
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.

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.
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.
Display time is not pts of the last block.
avcodec returns decoded subtitle with the correct timestamp.

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).

With CODEC_ID_HDMV_PGS_SUBTITLE use codec_{width,height} for
i_original_picture_{width,height} to correctly display
subtitles with a frame size that is different from the
video stream
