Re: [sv-bc] Request from the SV-CC

Cliff -- I'll plead mea culpa here.  I actually made the original
suggestion to CC in the face-to-face a while ago.  The context
of the issue is that there is no authoritative name for $unit
based names.

So, for example,
    f1.sv
    -----
       int C;
       // other stuff
    f2.sv
    -----
       int C;
       // other stuff

If f1.sv and f2.sv define different compilation units, you have
no ability to uniquely name the distinct declarations of "C".

So, either we all need to agree on one globally authoritative naming
scheme, or we have to provide a mechanism for mapping between
vendor approaches for the cases in which you really do care that
various tools in your tool chain have the same global name for such
declarations.

Since vendors (or at least "vendor") have already made determinations
about naming such compilation units, it seemed easier to just require
a mapping mechanism than to get into a long distracting argument
about how to name such compilation units.
