        * breakpoint.c (pending_break_support): New setting variable.
        (break_command_1): Account for pending_break_support setting
        when creating pending breakpoints.
        (set_breakpoint_cmd, show_breakpoint_cmd): New functions.
        (_initialize_breakpoint): Add "set breakpoint pending" and
        "show breakpoint pending" commands.
