a0131ad117 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.

fe678071c2 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>")

bcaf3321ab 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.

0e478acfb7 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).

d88e11ffe2 Fixed the unit numbers of the devfs `fd' devices. 
Made the devfs `fd' devices bug for bug compatible with the ones created
by MAKEDEV:
- ownership is bin.bin, not root.wheel, except for std*.  The devfsext
  interface doesn't seem to allow specifying the ownership of /devfs/fd,
  so it's still incompatible.
- std* aren't links to fd/[0-2].

2296883240 The recently introduced sv_sendsig entry of the sysentvec structure 
is incorrectly set to 0, for the purpose of "ignoring" the signal.
This does not ignore the signal, but rather, executes the function
at location 0 in kernel mode, which shortly thereafter causes a panic.

The sv_sensig entry for ibcs2 emulation should be set to the system's
normal sendsig routine.
