Andreas Rheinhardt 7de9c0e9d7 avcodec/flac: Don't use bytestream API unnecessarily
It makes no sense here, as flac_parse_block_header()
is not even supposed to advance the caller's pointer.

Andreas Rheinhardt 5089884e3c avcodec/flac: Move decoder+parser stuff into a new header, flac_parse.h
(The FLAC parser currently ignores the streaminfo block;
therefore some of this is decoder-only. Given that the FLAC
parser should probably use the streaminfo block, this stuff
is moved to flac_parse.h.)

Anton Khirnov 5fdaf312c5 flac: make avpriv_flac_parse_block_header() inline
This avoids all the ABI troubles associated with avpriv_.
Since this function is very small and does not depend on any tables,
making it inline should have no adverse effects.
