Hello, 

I'm looking for feedback, mostly on my infrastructure approach for
the following addition to RDA.  In one sentence, I'm going to add
introspect support.

The diff below probably won't apply cleanly, but will convey the 
sense of my proposed first-step.

Basically, I'll add a new subdirectory rda/introspect, and tweak
the top-level rda makefile and configure to include it.  I'll make
the top-level remote protocol parser recognize the 'Q' and 'q' msgs
that implement introspect, and have it call functions that do all
the work.  Then I'll implement two separate libraries in the
introspect directory -- one that simply provides empty stubs to 
satisfy those calls (for targets that don't implement introspect), 
and a second that actually implements introspect.

The first check-in will include only the dummy library.

Anybody suggest any improvements to this approach?

Thanks,
Michael
