The -P option, when specified opens a pidfile to a given path.
Both daemons also install a default pid file to the corresponding
locations, that is, /var/run/nfsd.pid and /var/run/rpcbind.pid.

Fix a bug in rpcbind for multihomed hosts. If the server had interfaces on
two separate subnets, and a client on the first subnet contacted rpcbind at
the address on the second subnet, rpcbind would advertise addresses on the
first subnet. This is a bug, because it should prefer to advertise the
address where it was contacted. The requested service might be firewalled
off from the address on the first subnet, for example.

usr.sbin/rpcbind/check_bound.c
	If the address on which a request was received is known, pass that
	to addrmerge as the clnt_uaddr parameter. That is what addrmerge's
	comment indicates the parameter is supposed to mean. The previous
	behavior is that clnt_uaddr would contain the address from which the
	client sent the request.

usr.sbin/rpcbind/util.c
	Modify addrmerge to prefer to use an IP that is equal to clnt_uaddr,
	if one is found. Refactor the relevant portion of the function for
	clarity, and to reduce the number of ifdefs.
