Prepare Tests for FileMan 22.2 submission

The testing of Fileman 22.2 highlighted some eventual problems with the
RAS tests, fix the commands to account for the changes that will come.

Update the wait_re function to compile the supplied string argument into a
case insensitive expression to be used in the match.

Prepare for:

The changing of "Press RETURN" to "Press Enter" in prompts by removing the
references to those keys and waiting for "to continue".
Changing of phrase used to exit by using a multiwait to capture both
possible phrases
Changing of case of upper to mixed in prompts by using the new
case-insensitive wait_re functions for certain commands.

Add Exceptions for VA Fileman 22.2 routines

Add XINDEX exceptions for the new routines that are added in the
FileMan22.2 submission.

DINVGTM/DINVGUX: New routines that contain logic specific to GT.M on VMS
and Unix.  Routines similar to this for other platforms were exempted and
the error found in both routines has been exempted in Kernel.

DMUD*: MUnit Test routines, should not be run in normal operation.  If
using the OSEHRA framework, the MUnit routines will be installed prior to
running these tests.
