- Moved the Workbench console stream initialization into the

initialization code for the stdin/stdout/stderr streams and
  out of the program parameter setup.

- The current program name is now set up in the stdlib
  initialization function.

- Simplified the machine test code; moved the FPU check into
  the math initialization code.

- Added more safety checks to verify that file descriptor
  file handles are valid.
