Clean up some extern decls.

Mostly, this hoists extern decls out of .c files and into .h files.
That way, we're more likely to catch errors if the interfaces change.
* alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
declare xg_mark_data.
* dispextern.h (x_frame_parm_handlers):
* font.h (Qxft):
* lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
(Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
(Qultra_bold, Qoblique, Qitalic):
Move extern decl here from .c file.
* alloc.c (xg_mark_data) [USE_GTK]:
* doc.c (Qclosure):
* eval.c (Qlexical_binding):
* fns.c (time) [!HAVE_UNISTD_H]:
* gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
(Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
* image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
* lread.c (Qinternal_interpreter_environment):
* minibuf.c (Qbuffer):
* process.c (QCfamily, QCfilter):
* widget.c (free_frame_faces):
* xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
* xfont.c (x_clear_errors):
* xterm.c (x_frame_parm_handlers):
Remove now-redundant extern decls.
* keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
* xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
Now static.
* xfaces.c: Remove unnecessary static decls.
* xterm.c (updating_frame): Remove decl of nonexistent object.
