Title: Implementation of breakpoints, with more refactoring.

Breakpoints are disabled in this landing because gdb seems to require
stepi to get around some internally-set breakpoint. But they work.
There's nothing particularly surprising in the implementation.

This one is a bit interesting so will leave open for a bit.
