        * observer.sh: Add struct so_list declaration.
        * Makefile.in: Add dependencies on observer.h for solib.c and
        breakpoint.c.
        * breakpoint.c (disable_breakpoints_in_unloaded_shlib): New
        function.
        (_initialize_breakpoint): Register
        disable_breakpoints_in_unloaded_shlib as an observer of the
        "solib unloaded" observation event.
        (re_enable_breakpoints_in_shlibs): For bp_shlib_disabled breakpoints,
        call decode_line_1 so unfound breakpoint errors are silent.
        * solib.c (update_solib_list): When a solib is discovered to have
        been unloaded by the program, notify all observers of the
        "solib unloaded" observation event.
