Update (internal) list of breakpoints when creating / modifying / deleting using MI commands This commit correctly updates internal breakpoint list when breakpoints are manipulated through MI. In that case, GDB does not generate breakpoint events, so this commit adds command post-execute hook that injects an artifical breakpoint event back onto an event queue.
