* tracepoint.c (finish_tfind_command): improved algorithm for
        deciding when we've "stepped" into a new stack frame.
        (map_args_over_tracepoints): loop over tracepoint list "safely",
        since list elements may be deleted during loop.
        (read_actions): add actions to history list.

whether we have made a transition from one function to another.
If so, we'll print the "stack frame" (ie. the new function and
it's arguments) -- otherwise we'll just show the new source line.
This determination is made by checking (1) whether the current

Hack: if the FP wasn't collected, either at the current or the
previous frame, assume that the FP has NOT changed. */
