Removed declarations of nonexistent functions copyoutstr(), fuiword() and suiword().  They are no longer referenced in the machine-independent code (I think fuiword() and suiword() were only used by old versions of ptrace(), and copyoutstr() by old versions of exec).

Added `const' where appropriate.

Changed u_int to size_t' where appropriate.

Named last arg of copystr() and copyinstr() better.
