The get_maint_bp_addr procedure will be shared by other test suite, so move it to gdb-utils.exp. Following Andrew's suggestion, I renamed get_maint_bp_addr to gdb_get_bp_addr, since it would have handled normal breakpoints in addition to the internal ones. Note that there is still room for improvement in this procedure, which I indicated in comments nearby.
