  Add basic rwlock API for uspace so that VFS can be designed/implemented using
  this API. So far, the implementation of this API merely wraps futexes into
  rwlocks. Real rwlocks are wanted by ticket #54.
  
  Using the new rwlock API, replace the VFS node content futex with an rwlock.
  Lock the contents rwlock as reader on reads and as writer on writes.
