Initial support for using idb over gdb as a backend debugger. Enable this with the -Obackend-debugger=idb option, this is not ready for widespread use however as the mi interface to idb is flaky and in some places completely different from that of gdb.

In particular this doesn't work for MPI queues, only shows
one thread per program and doesn't show variables or paramaters
for any functions.  Basically right now all it shows is function
names in stack traces.
