objc PATCH: add missing functions to libobjc/libobjc.def

[Nicola Pero]

GNUstep's libobjc has quite a maintained and updated libobjc.def - GCC's
one seems old in comparison - I'd like to merge the differences to get
GCC's one up to date (and reduce the differences).

I'm not sure that the libobjc shipped with GCC compiles properly on
Windows :-) I don't have such a system, but from the GNUstep howtos I
think on windows people normally replace the libobjc.a which is installed
by GCC with gnustep's libobjc (because gnustep's one compiles properly as
a DLL on windows).  It would be quite nice if this step wasn't required
... if the libobjc shipped with gcc would compile nicely as a proper DLL.

So, I suppose this patch is a first start ... libobjc.def is supposed to
contain the list of useful functions to expose, and some are missing, so
here is a patch adding them.

        * libobjc.def (__objc_runtime_mutex, __objc_is_multi_threaded,
        __objc_runtime_threads_alive, objc_set_thread_callback,
        objc_condition_allocate, objc_condition_deallocate,
        objc_condition_wait, objc_condition_broadcast,
        objc_condition_signal, objc_set_error_handler): Added.
