Unprotected SSVN in XPDR

Joel, please make sure this updated routine ends up in a build.

From Bhaskar, the diff and a little explanation. NOTE the comments at the bottom about wrapping calls.

Notice the replacement of the use of the SSVN ^$R() with a call to SILENT^%RSEL(). I erred in my report that the XPDR I submitted would work on other MUMPS systems - in actuality, usage of ^$R() and SILENT^%RSEL would have to be wrapped.

Note: I think only the line that replaces the usage of ^$R() with
usage of SILENT^%RSEL() is relevant. The other changes are probably
incidental and reflect different patch levels between the routine I
originally changed and newer versions of XPDR.m.

As Bhaskar noted, SILENT^%RSEL still needs to be wrapped. In other words, it's specific to GT.M. I'm not sure how to handle this one. X ^%ZOSF("RSEL") seems to be interactive and not what we want.

This routine is not designated as GTM specific and will need to incoporate the old logic for non GTM M environments. I'll make a change to handle GTM and others.

XPDR will be changed to work in GTM and Cache
