Peter Meerwald 537f430c99 resampler: Resample first followed by remapping if have more out channels than in channels 
Reintroduces a cleaned-up version of commit 30ce3a14e5 which
was reverted by 1ce71cbd82; for more information see
http://thread.gmane.org/gmane.comp.audio.pulseaudio.general/17479/focus=17487

The patch intends to reduce computational load when resampling AND remapping. The PA
resampler performs the following steps:

sample format conversion -> remapping -> resampling -> sample format conversion

In case the number of output channels is higher than the number of input channels, the
resampler has to be run more often than necessary. E.g. in case of mono to 4-channel remapping,
the resampler runs on 4 channels separately.

To ímprove this, the PA resampler pipeline is made adaptive:

if out-channels <= in-channels:
  sample format conversion -> remapping -> resampling -> sample format conversion
if out-channels > in-channels:
  sample format conversion -> resampling -> remapping -> sample format conversion

HACKING:
	In order to run pulseaudio from the build dir __OPTIMIZE__ should be
	disabled (look at src/pulsecore/core-util.h::pa_run_from_build_tree()),
	this can be done by passing "CFLAGS=-O0" to the configure script:
	  ./autogen.sh
	  CFLAGS="-ggdb3 -O0" LDFLAGS="-ggdb3" ./configure
	  make
	  ./src/pulseaudio -n -F src/default.pa -p $(pwd)/src/
