the 128-bit sigset_t changes by moving conditionally (rarely) executed
code to the beginning where it is always executed, and since this code
now involves 3 128-bit operations, the pessimization was relatively
large. This change speeds up lmbench's pipe latency benchmark by
3.5%.
Fixed style bugs in CURSIG().
very bloated, first with 128-bit sigset_t's, then with locking in the
SMP case, then with locking in all cases. The space bloat was probably
also time bloat, partly because the fast path through CURSIG() was
pessimized by the sigset_t changes. This change speeds up lmbench's
pipe-based latency benchmark by 4% on a Celeron. <sys/signalvar.h>
had become very polluted to support the bloat.
in favor of the new-style per-vif socket.
this does not affect the behavior of the ISI rsvpd but allows
another rsvp implementation (e.g., KOM rsvp) to take advantage
of the new style for particular sockets while using the old style
for others.
in the future, rsvp supporn should be replaced by more generic
router-alert support.

filesystem lookup() routine if it unlocks parent directory. This flag should
be carefully tracked by filesystems if they want to work properly with nullfs
and other stacked filesystems.
VFS takes advantage of this flag to perform symantically correct usage
of vrele() instead of vput() if parent directory already unlocked.
If filesystem fails to track this flag then previous codepath in VFS left
unchanged.
Convert UFS code to set PDIRUNLOCK flag if necessary. Other filesystmes will
be changed after some period of testing.

We now see something like ``No output from the 3 files processed''.
Lump all output for a given periodic argument together so that
people with /usr/local/etc/periodic/daily (for example) will
get the output of those jobs together with the normal daily run
rather than getting a second email.

Also, boot would proceed immediately in the absence of a path as

not, fall back to load kernel&modules behavior.
Some further factorizing. I deem this code to be mostly readable by
now! :-)
