call XQueryPointer to get coordinates.
(popup_get_selection): Do not set popup_activated_flag to zero,

connection's local address in :local property of contact info.
(Fmake_network_process): Record local network address for new
client processes in :local property of contact info.
Count LAST_LINE_MISFIT in scroll margin for end of window.
Move label too_near_end before setting SCROLL_MARGIN_POS.
Set LAST_LINE_MISFIT before jumping there.
(try_scrolling): Calculate amount_to_scroll better in
scroll_conservatively case. If scrolling that much doesn't change
STARTP, move it down one line.
(setup_echo_area_for_printing): Kill Emacs if no selected frame.

with masking off control-key with mac-reverse-ctrl-meta.
If it is non-nil, run timers. Use an unwind-protect to requeue
the events that were read ahead.
(popup_get_selection_unwind): New subroutine.
(popup_get_selection_queue): File-scope variable now holds that queue.
(xmenu_show): Pass 0 for DO_TIMERS to popup_get_selection.
(xdialog_show): Pass 1 for DO_TIMERS to popup_get_selection.
Use an unwind-protect to pop down the dialog box.
(xdialog_show_unwind): New subroutine implements that.
(struct catchtag): New elt interrupt_input_blocked.
(unwind_to_catch): Restore interrupt_input_blocked from saved value.
