Add snd_emu10kx driver for Creative SoundBlaster Live! and Audigy series

sound cards with optional pseudo-multichannel playback.

It's based on snd_emu10k1 sound driver. Single channel version is available
from audio/emu10kx port since some time.

The two new ALSA header files (GPLed), which contain Audigy 2 ("p16v") and
Audigy 2 Value ("p17v") specific interfaces, are latest versions from ALSA
Mercurial repository.

This is not connected to the build yet.
