289ccde0bd Correct the handling of NOCLDSTOP when using sigvec() 
Make the SA_NODEFER handling more correct, previously if you called
sigaction to set a handler and had SA_NODEFER set, and manually masked
the signal itself in sa_mask, and when you read the settings back later,
you'd find SA_NODEFER incorrectly cleared.

dc7dfe8990 Add a SV_NODEFER and SV_RESETHAND #define, after Bruce pointed out that 
a program that was saving and restoring a signal via sigvec() was not
doing the complete job if either of these bits had been set via sigaction.

30957dad06 re-add the ps_signodefer. The interaction between SA_NODEFER and the 
sa_mask was "non intuitive" and broke another of bde's test cases.

2eb80d36fe Because of the way that ptrace() now calls procfs routines to read/write 
the process's memory, it was possible for the procfs_domem() call to
return a residual leftover, but with no errno.  Since this is no good for
ptrace which ignored the the residual, remap a leftover amount into an
errno rather than fooling the caller into thinking it was successful when
in fact it was not.

a1fbfdff14 Fixed reference counting related to relookup(). relookup() must 
be called with the directory referenced, and this reference will
be dropped iff relookup() fails, so the value returned must not be
ignored.

6ac3b69d76 Eliminate panic("rtfree") caused by double-freeing the route 
when rt == rt->rt_gwroute .  rt == rt->gwroute shouldn't happen
in the first place, but that's another problem.

(try "route add -host <hostonmynet> <hostonmynet>; ping <hostonmynet>;
route delete <hostonmynet>")

e206cebf59 Change v_usecount & v_writecount from a short to an int. As shorts they 
can and will overflow on large machines - especially on machines with
filesystems with lots of files (like netnews servers), and the result
is a "free vnode isn't" panic or worse.
This fixes one of the causes of these panics that I've been experiancing on
wcarchive.

8dec8ed218 Nit: according to the Harvard code, it is necessary to clear the timestamp 
counter before loading the performance-monitor control register.  I'm
not sure I believe this, but we'll follow their lead for the moment.
As a result of this commit, the performance-monitoring test program that
I wrote now works (the program will find its way to share/examples).
