Change the sched_lock to a mutex. This fixes, among other things, the infamous
"telnet localhost &" problem. The real bug in that case was that the sched_lock
which is by design a non-recursive lock, was recursively acquired, and not
enough releases made us hold the lock in the idle loop, blocking scheduling
on the other processors. Some of the other processors would hold the biglock though,
which made it impossible for cpu 0 to enter the kernel... A nice deadlock.
Let me just say debugging this for days just to realize that it was all fixed
in an old diff noone ever ok'd was somewhat of an anti-climax.

This diff also changes splsched to be correct for all our architectures.

Clarify (from art@)

The spl() functions block interrupts of equal or lesser priority, not of
higher priority. This man page could use some more improvement, but this
paragraph was too misleading to be ignored.

Don't incorrectly document splserial() as spltty().

General man page cleanups, mostly to remove trailing whitespace, hard
sentence breaks, and other such things.

Update to match changes to splsoftclock()/spllowersoftclock().
Plus splserial() -> spltty(), splsoftserial() -> splsofttty().

- remove all trailing whitespace
* except when it is escaped with a `\' at the end of the line
- fix remaining .Nm usage as well
- this is from a patch I received from kwesterback@home.com, who

- this is from a patch I received from kwesterback@home.com, who has been
working on some scripts for fixing formatting errors in mdoc'd man pages

Ok, so there could be a cost/benefit debate with this commit, but since I have
the patch we might as well commit it...
