6d7eaba845 decoder/dsdiff: refactor the main decoder loop
Check for STOP before decoding the first chunk.  This reduces the
command latency.

40db9dff3b decoder/dsdiff: support only one "DSD" chunk
Eliminate the loop from dsdiff_stream_decode().  It makes the code
complex, real-world files with multiple DSD chunks are outside of the
specification, and the "chunk_size" variable would be bogus anyway.

This allows the compiler to discard buffer contents between two
iterations.

6fe06cad98 decoder/dsf: count the blocks, not the remaining bytes
Prepare refactoring the whole plugin to use blocks instead of bytes.
A block is the smallest addressable unit, and it will simplify the
seeking code.

2335fdbb5a decoder/dsf: allow channel setups other than stereo
This finishes the multi-channel support.  Development of the feature
was started with commit 02cc77cd8

1b6f7c3eb7 decoder/dsf: eliminate another hard-coded stereo mode assumption
When calculating the upper bound using the "sample count" format
header, don't assume it's stereo.

d8782ce5fd decoder/dsf: simplify dsf_to_pcm_order()
Don't pass the buffer size to the function, as it's known at compile
time.  Use "restrict" on the pointer arguments, and merge the two
loops, which allows the compiler to optimize this loop with a few SSE2
instructions.

dedc2986c6 decoder/dsf: fix noise at end of malformed file
Read one block at a time.  This discards the last partial block, which
cannot be interleaved anyway.  Previously, uninitialised memory was
used to interleave the last block, which generated some noise.

43a1a0f3ab decoder/faad: remove size!=0 check
Since we already checked InputStream::KnownSize(), we can assume that
GetSize() returns a valid value, and this check is obsolete.
