Fix ticket #100 by implementing STREAM-FILE-POSITION

Implements STREAM-FILE-POSiTION and (SETF STREAM-FILE-POSITION).

* code/stream.lisp: * Add support for Gray streams in FILE-POSITION. * pcl/gray-streams.lisp: * Define STREAM-FILE-POSITION and (SETF STREAM-FILE-POSITION). * Add methods on FUNDAMENTAL-STREAM, CHARACTER-INPUT-STREAM, and CHARACTER-OUTPUT-STREAM. * code/exports.lisp: * Export STREAM-FILE-POSITION.
