bfs: Use the QueryParserUtils instead of its own copy.

* Ingo copied the methods into a shared location, and then obviously
  "forgot" to let BFS use them. As a side note for Ingo: the complete
  error GCC reported was "std::fssh_size_t" not defined with the macro
  wrapper as code location. The actual problem was a "using std::size_t"
  in some C++ header that accidentally got included after the wrapper.
* The shared Query code is not yet used. That'll be done another time.
* Renamed BFS_SHELL define to FS_SHELL, such that QueryParserUtils can be
  used in any file system shell, not just the bfs_shell.
