  Log:
  The remaining part of nmount/omount/rootfs mount changes.  I cannot sensibly
  split the conversion of the remaining three filesystems out from the root
  mounting changes, so in one go:
  
  cd9660:
          Convert to nmount.
          Add omount compat shims.
          Remove dedicated rootfs mounting code.
          Use vfs_mountedfrom()
          Rely on vfs_mount.c calling VFS_STATFS()
  
  nfs(client):
          Convert to nmount (the simple way, mount_nfs(8) is still necessary).
          Add omount compat shims.
          Drop COMPAT_PRELITE2 mount arg compatibility.
  
  ffs:
          Convert to nmount.
          Add omount compat shims.
          Remove dedicated rootfs mounting code.
          Use vfs_mountedfrom()
          Rely on vfs_mount.c calling VFS_STATFS()
  
  Remove vfs_omount() method, all filesystems are now converted.
  
  Remove MNTK_WANTRDWR, handling RO/RW conversions is a filesystem
  task, and they all do it now.
  
  Change rootmounting to use DEVFS trampoline:
  
  vfs_mount.c:
          Mount devfs on /.  Devfs needs no 'from' so this is clean.
          symlink /dev to /.  This makes it possible to lookup /dev/foo.
          Mount "real" root filesystem on /.
          Surgically move the devfs mountpoint from under the real root
          filesystem onto /dev in the real root filesystem.
  
  Remove now unnecessary getdiskbyname().
  
  kern_init.c:
          Don't do devfs mounting and rootvnode assignment here, it was
          already handled by vfs_mount.c.
  
  Remove now unused bdevvp(), addaliasu() and addalias().  Put the
  few necessary lines in devfs where they belong.  This eliminates the
  second-last source of bogo vnodes, leaving only the lemming-syncer.
  
  Remove rootdev variable, it doesn't give meaning in a global context and
  was not trustworth anyway.  Correct information is provided by
  statfs(/).
