Tim Walker 41244e13d5 flac: don't check the number of channels before setting the channel layout.
This is unnecessary, as ff_flac_set_channel_layout can handle any number of channels.

Anton Khirnov 594d4d5df3 lavc: add a wrapper for AVCodecContext.get_buffer().
It will be useful in the upcoming transition to refcounted AVFrames.

Justin Ruggles 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.

Mans Rullgard 93e7ef9a24 flacdec: allocate sample buffers with av_malloc
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.
