Add RULES(NOLAXFILEIO)

We want to avoid I/O-errors and -problems with the standard that user-defined files have to be explicitly opened before and closed after processing but not system-defined files:

Therefore we would like to get a new RULES suboption such as [NO]LAXFILEIO:
- With LAXFILEIO as default

NOLAXFILEIO means that
- OPEN or CLOSE of SYSIN or SYSPRINT will be flagged with a message
- For any file other than SYSIN or SYSPRINT, if there is no OPEN or no CLOSE of that, then its usage will be flagged with another message

    This is not something we can do reliably at compile-time - even if there are no OPEN statements in the current compilation units, a file may have been opened in the calling routine. And if there are OPEN statements, they may be conditional and so ...

    We could have an option that would lead the code to raise a condition if an implicit OPEN were attempted, but that should probably be a new RFE
