Tweak previous. Copy over to sa_sigmask whatever was masked before
we were an SA process.

src/sys/sys [wrstuden-revivesa]: savar.h

Log Message:
Check in merge of signal handling changes. This is a fairly-direct port
of what existed before SA was removed.

Expicitly add a sigset_t named sa_sigmask to sadata, and use it to
note what signals are masked for an SA thread. Clear it out when
going SA.

Tweak how we clear LW_SA when we're allocating space for delivering a
signal - the whole point is we don't want to generate a BLOCKED upcall,
so we have to clear it BEFORE we allocate, not after (like the old code seems
to have done).

While here, tweak indentation in savar.h to improve readability.

src/sys/kern [wrstuden-revivesa]: kern_lwp.c kern_time.c

Log Message:
First cut at porting SA timer code to -current. Slightly modified
so that we now use the timer_intr soft interrupt to do what we used
to do in itimerfire(). Also, use sa_mutex and p_lock instead of
the kernel lock.

Open question about what locks we can lock while holding
the timer lock.

Modified Files:
src/sys/kern [wrstuden-revivesa]: kern_sa.c

Log Message:
Merge sa_setwoken() and sa_unblock_userret(). The only time
sa_unblock_userret() would be called would be the time when sa_setwoken()
would not return, so just rename sa_setwoken() to be sa_unblock_userret()
and merge the beginnings of the routines together.

Purge sa_vp_reposess() with impunity. It hasn't been used for years,
is buggy, and is confusing.

Comment about the only way we'd ever come back to sa_unblock_userret()
after calling mi_switch() is if the process is exiting and we've been
made runable. If that happens, just exit.

Add comments about what sa_unblock_userret() is doing to preserve
our concurrency cap.
