Fix problems with 32-bit wide-int build exposed by MinGW
lisp.h (XPNTR): Move definition to after XTYPE, to avoid compilation error in an unoptimized build when !USE_LSB_TAG. src/w32heap.c (DUMPED_HEAP_SIZE): For 32-bit wide-int build, use the same larger value as for the 64-bit build. src/w32term.h (SCROLL_BAR_PACK): Cast the result to UINT_PTR to avoid compiler warnings. src/w32proc.c (Fw32_get_codepage_charset, Fw32_set_keyboard_layout): Avoid compiler warnings about cast from integer to pointer of different size. src/w32menu.c (menubar_selection_callback, w32_menu_show): Cast to UINT_PTR instead of EMACS_INT, to avoid compiler warnings about casting from integer to pointer of different size. (add_menu_item): Pass the help-echo string as a pointer to Lisp_String, not as a Lisp_Object. (w32_menu_display_help): Use make_lisp_ptr to reconstruct a Lisp string object from its C pointer. src/w32fns.c (w32_msg_pump) <WM_EMACS_UNREGISTER_HOT_KEY>: Use make_lisp_ptr instead of XIL, to reconstruct a Lisp_Cons from its C pointer. <WM_EMACS_TOGGLE_LOCK_KEY>: msg.lparam is now a C integer. (Fx_create_frame): Type-cast the result of XFASTINT to avoild compiler warnings about size differences. (Fw32_unregister_hot_key): Pass the tail of w32_grabbed_keys as a pointer to a Lisp_Cons struct, not as a disguised EMACS_INT. (Fw32_toggle_lock_key): Pass the new state of the key as a C integer; use -1 for nil. Doc fix. src/.gdbinit (xgetsym): New subroutine. (xsymname, xsymbol): Use it. (xprintsym): No need to call xgetptr.
