This solves the problems with having to deal with howmany and which
devices are open.
For hysterical reasons ONLY, make a link to both the acdNa & acdNc devices.
This fixed the problem on the 3 platforms I've been able to test on.
I'm still of the oppinion that the BIOS should take care of this,
however some board makers only apply this when they spot a
SBLive! soundcard, but the problem exists even without a SBLive!.
This fix should probably go somewhere else, but for now I'll
keep it here since we havn't got a central place to put
such things.

make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.
Sorry john! (your next MFC will be a doosie!)

The only caller outside of M_ASLEEP was the ata driver, which called both

asleep() and await() pair. M_ASLEEP was unused.

around, use a common function for looking up and extracting the tunables
from the kernel environment. This saves duplicating the same function
over and over again. This way typically has an overhead of 8 bytes + the
path string, versus about 26 bytes + the path string.
