mount_* programs. While we're at it, collapse the four now-identical mount programs for devfs, fdesc, kernfs, and procfs into links to a new mount_std(8) which can mount any really generic filesystem such as these when called with the appropriate argv[0]. Also, convert the mount programs to use sysexits.h.
