Various changes lifted from the OpenBSD cvs tree:

txdr_hyper and fxdr_hyper tweaks to avoid excessive CPU order knowledge.

nfs_serv.c: don't call nfsm_adj() with negative values, windows clients
could crash servers when doing a readdir of a large directory.

nfs_socket.c: Use IP_PORTRANGE to get a priviliged port without a spin
loop trying to bind().  Don't clobber a mbuf pointer or we get panics
on a NFS3ERR_JUKEBOX error from a server when reusing a freed mbuf.

nfs_subs.c: Don't loose st_blocks on NFSv2 mounts when > 2GB.
