Clean up prototypes for Lisp variables/symbols. Put decls for them with the other stuff related to the file they're in. In the process, fix a few places with incorrect initialization of symbols and variables. -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2010-03-12 Ben Wing <ben@xemacs.org> * lisp.h: * lisp.h (redo-symbols): Removed. Put the Lisp variables and symbols where they belong, with other stuff related to the file they're in. * event-Xt.c (THIS_IS_X): * event-Xt.c (syms_of_event_Xt): * event-Xt.c (reinit_vars_of_event_Xt): * event-gtk.c: * event-gtk.c (syms_of_event_gtk): * event-gtk.c (reinit_vars_of_event_gtk): * event-stream.c: * event-stream.c (syms_of_event_stream): * event-stream.c (reinit_vars_of_event_stream): * events.c (reinit_vars_of_events): * events.c (vars_of_events): `sans-modifiers' was defsymbol'ed more than once. Move it to events-stream.c. `self-insert-command' was defsymbol'ed more than once. Vevent_resource should be staticpro_nodump()ed as it's declared in a reinit_*() method. * lread.c (vars_of_lread): Vfile_domain wasn't staticpro'ed. * minibuf.c: * minibuf.c (reinit_complex_vars_of_minibuf): Vminibuffer_zero and Vecho_area_buffer weren't staticpro'ed.
