Get rid of per filesystem VFS_OUT method switch and IPC unmarshalling.

  • libfs now understands the notion of VFS_OUT operations and provides the single version of the switch
  • libfs now automatically takes care of some libfs provided operations, such as lookup and stat; filesystem need not be even aware of these
  • one filesystem time per libfs instance
  • plb_get_char() no longer a libfs operation
  • filesystem implemenations need not worry about IPC with the exception of VFS_OUT_READ/WRITE methods and filesystems that depend on doing extra IPC in these and similar methods, such as devfs
  • Property mode set to 100644
