This is unnecessary, as ff_flac_set_channel_layout can handle any number of channels.

Fixes Bug 402

It will be useful in the upcoming transition to refcounted AVFrames.

Also reorder some other #include when applicable.

Although the libFLAC decoder cannot handle such a change, it is allowed by the
spec and could potentially occur with live streams.

Also, return an error on allocation failure.

Pass pointer to sample buffer instead of channel number to various
functions called from decode_subframe().  Also simplify a few
expressions within this function.

Reversing the lpc coefficient order simplifies indexing in
the filter.

The buffers are only allocated once, although it can happen from
any of a few different places, so there is no need to use realloc.
Using av_malloc() ensures they are aligned suitably for SIMD
optimisations.

This value does not need to be persistent across calls.

fixes Bug 209

CC: libav-stable@libav.org

Recent versions of gcc (4.4+) no longer give false positive warnings.

Deprecate avcodec_decode_audio3().
Implement audio support in avcodec_default_get_buffer().
Implement the new audio decoder API in all audio decoders.

Specifically, ff_flac_parse_streaminfo, ff_flac_is_extradata_valid and
ff_flac_parse_block_header

Adds an additional check before reading the next block header and avoids a
potential integer overflow when checking the metadata size against the
remaining buffer size.

It's more readable and less prone to breakage.

None of these symbols should be accessed directly, so declare them as
hidden.

AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.
