* dbxread.c, partial-stab.h (near N_SO): SO stabs with blank

	names mean end of .o file.
	* infrun.c (wait_for_inferior):  Clean up multi-thread logic near
	top of routine.  Handle new thread notification cleanly.
	* lynx-nat.c (child_wait):  General cleanups, handle new LynxOS
	thread notification scheme.
	* (child_resume):  General cleanups, handle resumption of all
	threads properly.
