  x86: use the inline int8x8_fmul_int32 only if inline SSE2 is availbale
Merged-by: Michael Niedermayer <michaelni@gmx.at>

When mixing 3 front channels into 2, the center channel is mixed into left and right with the center mix level, not -3dB.

Don't decode further substreams if request_channel_layout
is a subset of the current substream's channel_layout.

Before, we would only discard further substreams if
request_channel_layout matched the substream's
channel_layout extactly, thus decoding additional
channels which the caller would probably end up downmixing.

SDL device reports double free or hangs when quiting.
Reseting variables solves the issue.

The issue is caused by double call of write_trailer callback.
It is called for the first time in write_packet when quit flag is set.
Second call comes from ffmpeg.c or may come from other client application.

Fixes compilation with MSVC. Also does not rely on on earlier config.h
include but include it directly.

Fixes invalid reads in fuzzed7.ivf.

For non-avx optims, this saves 8 movs.

  dcadsp: add int8x8_fmul_int32 to dsp context

See: 481a46a4Merged-by: Michael Niedermayer <michaelni@gmx.at>

It is currently declared as a macro who is set to inlinable functions,
among which a Neon and a default C implementations.

Add a DSP parameter to each inline function, unused except by the
default C implementation which calls a function from the DSP context.

On an Arrandale CPU, gain for an inlined SSE2 function vs. a call:
- Win32: 29 to 26 cycles
- Win64: 25 to 23 cycles
