Trying to rebuild parity on a degraded set is bogus, so don't allow that.

Also, check sooner for a RAID 0 set, since rewriting parity makes no
sense there either.

Once upon a time, long long ago, there was a "fix" added to the
...
RAIDframe driver to stop it from eating too much kernel memory when
writing data. But that fix had a nasty side-affect of hurting write
performance (*much* more than I thought it would). These changes nuke
that "fix", and instead put in a more reasonable mechanism for limiting
the number of simultaneous IO's which can be happening for each RAID device.
The result is a noticeable improvement in write throughput. The End.

Allow re-writing parity on a RAID 0 to trivially succeed, and to set the
...
clean bit. This is somewhat bogus as RAID 0 does not have any parity,
but is a slightly cleaner than other solutions, and makes the handling
of clean bits for RAID 0 consistent with the handling of clean bits at
other RAID levels.

Disallow interrupting parity re-writes or copybacks by removing PCATCH
...
from the tsleep()'s (they probably shouldn't have been there in the
first place!). Making parity re-writing and copybacks interruptable
will require re-designing how a few things are done (e.g. how memory
is freed for structures shipped off to routines that run asynchronously
relative to the calling routine). Fix a few other tsleep's while we're at it.
