* xselect.c (x_reply_selection_request): Pass long array to
XChangeProperty so that 64 bit longs are handeled correctly.
(x_get_window_property): If format is 32 and long is bigger than 32
bits convert data from XGetWindowProperty from long array to int array.
(lisp_data_to_selection_data): When the input is a vector and the
format is 32, allocate a long array even if long is bigger than 32 bits.
(x_fill_property_data): Use char, short and long as the man page
for XChangeProperty specifies.  This way the data returned is OK for
both 32 and 64 bit machines.
(x_handle_dnd_message): Calculate size correctly even for 64 bit
machines.
(Fx_send_client_event): Undo change from 2005-02-05,
x_fill_property_data now handles that case.
