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.

The channel layout mask for non-standard layouts is typically stored at
the container level (as a vorbiscomment tag) for FLAC.

90fcac0e95 flacdec: allow mid-stream channel layout change
Although the libFLAC decoder cannot handle such a change, it is allowed by the
spec and could potentially occur with live streams.
