* breakpoint.h: Add breakpoint_re_set_objfile prototype. * breakpoint.c (create_overlay_event_breakpoint): Renamed from create_overlay_event_breakpoint_1, old create_overlay_event_breakpoint deleted. (breakpoint_re_set_objfile): Don't rescan all objfiles unnecessarily. (breakpoint_re_set): New function. * symfile.c (new_symfile_objfile): Call breakpoint_re_set_objfile instead of breakpoint_re_set. * objfiles.c (objfile_relocate): Likewise.
