AudioConverterFillComplexBuffer() doesn't always call its callback. A frame
queue is used to prevent skipped audio samples.

Allows to select a codec (encoder or decoder) only if it supports a
specific profile.
Adds ff_AMediaCodecProfile_getProfileFromAVCodecContext to convert an
AVCodecContext profile to a MediaCodec profile. It only supports H264
for now.
The codepath using MediaCodecList.findDecoderForFormat() (Android >= 5.0)
has been dropped as this method does not allow to select a decoder
compatible with a specific profile.
When checking pix_fmt mapping, some bitstreams are mapped to an
incorrect pix_fmt instead of being rejected (ENOSYS).
Actually, such bitstreams are not supported (FFmpeg encoder does not
produce such bitstream, such bitstream may come only from another
encoder for the moment).
- JPEG 2000 RCT 11/13/15/16 bit depths are mapped to a 8-bit FFmpeg
pix_fmt (e.g. bgr0), which is not expected.
- JPEG 2000 RCT 9/10/12/14 bit depths with alpha are mapped to a
FFmpeg pix_fmt without alpha (e.g. AV_PIX_FMT_GBRP9 for 9-bit with
alpha), which is not expected.
The order for choosing the pix_fmt is changed to the one used by YCbCr
selection (<=8 bit first).
" && !f->transparency" is added to the other lines.

This mimics the behaviour of other av_*_new_side_data().
This is not caught by the malloc check, since padding
is always added to the allocated size.

The only difference is that the first of them contains a
ff_h264_flush_change() call. While that is not necessary in the second
block, it should cause no problems either.
Reduce the verbosity of the reinit log message from info to verbose,
since now it will be displayed during every decode session.
Do it right before the MMCOs are applied to the DPB. This will allow
moving the frame_start() call out of the slice header parsing, since
generating the implicit MMCOs needs to be done after frame_start().
They are stored in the slice header, so technically they are per-slice
(though they must be the same in every slice). This will simplify the
following commits.
This function does not do any bitstream parsing and it depends on the
current frame being allocated, so this will allow the frame_start() to
be moved out eventually.
This will allow postponing the reference list construction (and by
consequence some other functions, like frame_start) until the whole
slice header has been parsed.
Currently it's done in the code that initialises the ref list for
MBAFF, which is not a logical place for it. Move it to the function that
parses the pred table from the bitstream, which is analogous to what is
done for the implicit weight table as well.
That function is currently very long and entangles bitstream parsing and
decoder configuration. This makes the code much harder to read than
necessary.
Begin splitting the code that configures the decoder state based on the
slice header information from the parsing of the slice header.

h264_parser: move the H264DSPContext to the parser context
H264Context is kept locally as it is currently needed for logging
(h->avctx as log context) and for is_avc and nal_length_size. These
later fields will later be obtained when the extradata parsing is
decoupled from the decoder. This code will be updated accordingly when
that commit is merged.

h264: decouple h264_ps from the h264 decoder
Main changes:
- a local GetBitContext is created for the various
ff_h264_decode_seq_parameter_set() attempts
- just like the old code, remove_sps() is adjusted so it doesn't remove
the pps.
Fixes decode with Ticket #631http://ffmpeg.org/pipermail/ffmpeg-user/attachments/20111108/dae58f17/attachment.mp4
but see next point as well.
- ff_h264_update_thread_context() is updated to work even when SPS
isn't set as it breaks current skip_frame code. This makes sure we
can still decode the sample from ticket #631 without the need for
-flags2 +chunks. (Thanks to Michael)
- keep {sps,pps}_ref pointers that stay alive even when the active
pps/sps get removed from the available lists (patch by michaelni with
additionnal frees in ff_h264_free_context() from mateo)
- added a check on sps in avpriv_h264_has_num_reorder_frames() to fix
crashes with mpegts_with_dvbsubs.ts from Ticket #4074http://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket4074/mpegts_with_dvbsubs.ts
- in h264_parser.c:h264_parse(), after the ff_h264_decode_extradata() is
called, the pps and sps from the local parser context are updated with
the pps and sps from the used h264context. This fixes fate-flv-demux.
- in h264_slice.c, "PPS changed between slices" error is not triggered
anymore in one condition as it makes fate-h264-xavc-4389 fails with
THREADS=N (Thanks to Michael)
