All annotate_breakpoints_changed calls are along-side

observer_notify_breakpoints_changed calls.  All, except the
init_raw_breakpoint one.  But that one is actually wrong.  The
breakpoint is being constructed at that point, and hasn't been placed
on the breakpoint chain yet.  It would be better placed in
install_breakpoint, and I actually started out that way.  But once the
annotate_breakpoints_changed are parallel to the observer calls, we
can fully move annotations to observers too.

One issue is that this changes the order of annotations a bit.
Before, we'd emit the annotation, and after call "mention()" on the
breakpoint (which prints the breakpoint number, etc.).  But, we call
the observers _after_ mention is called, so the annotation output will
change a little:

void
install_breakpoint (int internal, struct breakpoint *b, int update_gll)
{
  add_to_breakpoint_chain (b);
  set_breakpoint_number (internal, b);
  if (is_tracepoint (b))
    set_tracepoint_count (breakpoint_count);
  if (!internal)
    mention (b);
  observer_notify_breakpoint_created (b);

  if (update_gll)
    update_global_location_list (1);
}

I believe this order doesn't really matter (the frontend needs to wait
for the prompt anyway), so I just adjust the expected output in the
tests.  Emacs in annotations mode doesn't seem to complain.  Couple
that with the previous patch that suppressed duplicated annotations,
and, the fact that some annotations calls were actually missing (were
we do have observer calls), more changes to the tests are needed
anyway.

Tested on x86_64 Fedora 17.
