[Freeciv-Dev] patch: ANSI C fixes in gui-xaw (PR#565)

[David Pfitzner <dwp@xxxxxxxxxxxxxx>]

When trying out "gcc -ansi -pedantic" to re-check whether it was
usable, some warnings came up in gui-xaw which seemed worth fixing:

- ANSI C doesn't support casting function pointers to (void*), which
we do with input_dialog_create() in Xaw client.  This patch changes
arguments to XtCallbackProc, and then don't need to cast at all.

- timer_callback() uses caddr_t, which doesn't seem to be defined
-ansi, so change to use XtPointer instead -- which is more appropriate
anyway.
