xref issue #531 we've long talked about using gdb's remote stub API to make
it easier to use gdb to debug apps running under DR or a DR tool.
the goal is to hide the code cache and make debugging operate as it would
without DR.

using DR to extend the debugger with new capabilities is a separate topic.
