Put getmntopts() into libutil and install mntopts.h to /usr/include. Previously, they were private to sbin/mount and the other mount_* commands would take them from there via their Makefiles. However, puffs related stuff outside base (in pkgsrc for example) couldn't reach them this way. So for now, arrange it like NetBSD has it.
mount_nfs - Make rdirplus the default * It is really high-time we made rdirplus the default for NFS mounts. It improves client directory traversals by 300%. * With a SSD meta-data swapcache on the NFS server 'disk' latencies might as well be 'fully cached in ram' always. The bottleneck becomes the network regardless of server load. * Note that linux also defaults to using rdirplus mounts.
Remove NQNFS support. The mechanisms are too crude to co-exist with upcoming cache coherency management work and the original implementation hacked up the NFS code pretty severely. Move nqnfs_clientd() out of nfs_nqlease.c to a new file, nfs_kerb.c, and rename it nfs_clientd().
