Nice work, Doug.  In particular the architectural changes to move the
scripting language infrastructure support to a more generic naming,
and agnostic point of view.  (I guess we should have thought about
this way back when).

The only comments I have are the conflicts when dealing with areas
where an internal GDB, a Python, Guile, and some other future language
conflict might occur.  I noticed you removed the conditional
breakpoint check where only a Python "stop" callback can be attached
to a breakpoint, or a "traditional" GDB condition.  Your work is a
work in progress, so I am not going to worry too much at the moment.
But every "stop" callback attached to a breakpoint must be allowed to
run, even if the a previous "stop" callback indicated True to stop, or
a previous condition expression attached to GDB resolved to True.  I
guess we can look at this area again when your work is getting closer
to submission.

Thanks for the preview.  Are you aiming for 100% feature parity with
the Python work? (IE, frame filters, etc)

Cheers,

Phil
