Add snd_emu10kx driver for Creative SoundBlaster Live! and Audigy series

Browse Source 
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.

* Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>
* Driver p16v chips
* Version: 0.21
*
* FEATURES currently supported:
* Output fixed at S32_LE, 2 channel to hw:0,0
* Rates: 44.1, 48, 96, 192.
*
* Changelog:
* 0.8
* Use separate card based buffer for periods table.
* 0.9
* Use 2 channel output streams instead of 8 channel.
* (8 channel output streams might be good for ASIO type output)
* Corrected speaker output, so Front -> Front etc.
* 0.10
* Fixed missed interrupts.
* 0.11
* Add Sound card model number and names.
* Add Analog volume controls.
* 0.12
* Corrected playback interrupts. Now interrupt per period, instead of half period.
* 0.13
* Use single trigger for multichannel.
* 0.14
* Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
* 0.15
