* bfs_{read|write}_pages() now only try to lock - this fixes a possible

deadlock whenever someone without a lock (like the page_writer()) is calling
  this function.
* Added a new ReadWriteLock::TryLock() method.
* Renamed bfs_read_vnode() and bfs_release_vnode() to bfs_get_vnode() and
  bfs_put_vnode() just like those functions are called in fs_interface.h.
* Fixed a warning in BPlusTree::_SplitNode().
