make it signed, so that we don't get output like

context (reported on various mailing-lists, and part of PR kern/41114,
causing panic in pf(4) and possibly ipf(4) when BRIDGE_IPF is used).
Defer bridge_forward() to a software interrupt; bridge_input() enqueues
mbufs to ifp->if_snd which is handled in bridge_forward().
* A sign extension error creating the bridge ID corrupted the
priority (always making it the maximum).
* Do not catch STP packets on an interface for which STP is not
enabled -- it's a violation of the spec, and causes STP to fail on
neighboring bridges.
* An optimization to bstp_input() -- some information is already
known when we call it.

Cosmetic: don't open-code TAILQ_FOREACH().
Cosmetic: change types of variables to avoid oodles of casts: in
in6_src.c, avoid casts by changing several route_in6 pointers
to struct route pointers. Remove unnecessary casts to caddr_t
elsewhere.
Pave the way for eliminating address family-specific route caches:
soon, struct route will not embed a sockaddr, but it will hold
a reference to an external sockaddr, instead. We will set the
destination sockaddr using rtcache_setdst(). (I created a stub
for it, but it isn't used anywhere, yet.) rtcache_free() will
free the sockaddr. I have extracted from rtcache_free() a helper
subroutine, rtcache_clear(). rtcache_clear() will "forget" a
cached route, but it will not forget the destination by releasing
the sockaddr. I use rtcache_clear() instead of rtcache_free()
in rtcache_update(), because rtcache_update() is not supposed
to forget the destination.
Constify:
1 Introduce const accessor for route->ro_dst, rtcache_getdst().
2 Constify the 'dst' argument to ifnet->if_output(). This
led me to constify a lot of code called by output routines.
3 Constify the sockaddr argument to protosw->pr_ctlinput. This
led me to constify a lot of code called by ctlinput routines.
4 Introduce const macros for converting from a generic sockaddr
to family-specific sockaddrs, e.g., sockaddr_in: satocsin6,
satocsin, et cetera.
- initialise stp when the bridge is turned up, without this stp will keep
all interfaces disabled in a sequence like:
brconfig bridge0 add if0 add if1 stp if0 stp if1 up
- s/BRDGSPRI/BRDGSIFPRIO in brconfig.c:cmd_ifpriority()
add a command (ifpathcost) to change the stp path cost of the STP path cost of
an interface. Display the interface path cost with the others STP parameters.
compile-time by BRIDGE_IPF, and at runtime by brconfig with the {ipf,-ipf}
option on a per-bridge basis.
As a side-effect, add PFIL_HOOKS processing to if_bridge.
