    First, need to clear bdb state that might be left over from previous tests.
    Otherwise, the new breakpoints might get assigned different numbers.

    Now test the breakpoint commands.  NORMALIZE_WHITESPACE is needed because
    the breakpoint list outputs a tab for the "stop only" and "ignore next"
    lines, which we don't want to put in here.
