Well, if we add a function that returns true on supports_z_point_type
for Z_PACKET_SW_BP, then we also need to provide functions that
actually do insert/remove such breakpoints.  (I know that you have
that in the next patch, but each patch in a series should be
functionally correct on its own, so they really should be here.)

Otherwise looks good.

Thanks,
Ulrich
