This is a joined work of XK and me on improving the HLE plugin interface.

Browse Source 
It allows run time selection of backends (AOSound, DSound and NullSound).
It replaces the DSP_NULL plugin (works even better!)
It also includes improved thread handling on asound, and using some common functions on both
asound and windows.
