ac1f2e0a2e remap: move remapping code in separate file 
Move the remapping code into a separate file. Have functions to install custom
init functions that can install optimized versions, when they want.

a3f4a4f6ba resamples; refactor the channel remapping bits 
Move the channel remapping bits into a separate structure. We'll make this
structure global so that optimized versions can use it to perform the channel
remapping.

c1b6a87b27 alsa-sink: reduce the amount of smoother updates 
Exponentially increase the amount of time between smoother updates. We start
with a 2ms interval and increase up to 200ms intervals.
Smoother updates and the resulting linear regression take a fair amount of CPU
so we want to reduce the amount of updates.

b4e9942c2f resample: refactor the channel remapping a little 
Factor out the channel remap matrix code into a separate function.
Keep a pointer to the channel remapping function so we can install custom
functions.
Catch the common mono->stereo remapping case and install a custom, more
optimized function.

to regenerate it when dealing with s16 samples.

25724cdd40 Get rid of liboil 
Get rid of the liboil dependency and reimplement the liboil functions with an
equivalent C implementation. Note that most of these functions are deprecated in
liboil and that none of them had  any optimisations. We can further specialize
our handrolled versions for some extra speedups.

Make the coding style match the rest of pulseaudio more.

handrolled versions here.

c5bd72509e core: check return value of getgrnam_r() instead of errno 
According to POSIX getgrnam_r() returns the error code as return value,
and not in errno. Honour that.

Pointed out and inspired by a patch from Ted Percival.
