Module Name:    src
Committed By:   wrstuden

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