sound subsystem

[Havoc Pennington]

Hi,

Arjan asks that we move everything to use libasound rather than esound
or OSS. Because ALSA lets multiple apps output sound at once, esound
isn't really needed; the only functionality we lose is that remote apps
can't play sound on the local system, but that functionality was pretty
hosed with esound anyway.

I don't have a sense of how many things are accessing OSS/esound
directly, or how much work is involved here.
