Log Message:
Introduce a big change in the way file-I/O is treated, permitting us to
*trace* file-I/O for the first time:
(1) Library IO now uses a ForeignObj as a Handle instead of an opaque type.
(2) Completely re-implement all file-I/O functions using foreign imports
    instead of primitives.
(3) Fix some qualified naming errors: 
        Prelude.Handle -> IO.Handle
        Prelude.stdin  -> IO.stdin  etc
