here, it may be too late if we start queuing after we have already
stored some selection events into the kbd buffer.
(struct selection_event_queue, queue, x_queue_selection_requests)
(x_queue_event, x_unqueue_events, x_start_queuing_selection_requests)
(x_stop_queuing_selection_requests): Remove/move to xselect.c.
(x_catch_errors_unwind): Block input around final XSync.
(x_queue_selection_requests, x_queue_event)
(x_start_queuing_selection_requests)
(x_stop_queuing_selection_requests): Add new queue for selection
input events to replace previous XEvent queue in xterm.c.
(queue_selection_requests_unwind): Adapt to new queue.
(x_reply_selection_request): Adapt to new queue. Unexpect
wait_object in case of x errors (memory leak).
(x_handle_selection_request, x_handle_selection_clear): Make static.
(x_handle_selection_event): New function. May queue selection events.
(wait_for_property_change_unwind): Use save_value instead of cons.
Clear property_change_reply_object.
(wait_for_property_change): Abort if already waiting.
Use save_value instead of cons for unwind data.
(x_handle_property_notify): Skip events already arrived, but don't
free them, as "arrived" field is checked by wait_for_property_change,
and it will be freed by unwind or explicit unexpect_property_change.
(x_get_foreign_selection): Add to new queue.
(receive_incremental_selection): Don't unexpect wait_object when done
as it has already been freed by previous wait_for_property_change.
(kbd_buffer_unget_event): New function.
(kbd_buffer_get_event, swallow_events): Combine SELECTION events
and use x_handle_selection_event.
(mark_kboards): Don't mark x and y of SELECTION_CLEAR_EVENT.
* gtkutil.c: Make use_old_gtk_file_dialog non-static.
(xg_initialize): Moved DEFVAR_BOOL for use_old_gtk_file_dialog ...
* xfns.c (syms_of_xfns): ... to here.
Fx_file_dialog if only directories should be read.
* lisp.h: Fx_file_dialog takes 5 parameters.
* xfns.c (Fx_file_dialog): Both Motif and GTK version: Add
parameter only_dir_p.
In Motif version, don't put DEFAULT_FILENAME in filter part of the
dialog, just text field part. Do not add DEFAULT_FILENAME
to list of files if it isn't there.
In GTK version, pass only_dir_p parameter to xg_get_file_name.
* macfns.c (Fx_file_dialog): Add parameter only_dir_p. Check
only_dir_p instead of comparing prompt to "Dired". When using
a save dialog, add option kNavDontConfirmReplacement, change title
to "Enter name", change text for save button to "Ok".
* w32fns.c (Fx_file_dialog): Add parameter only_dir_p. Check
only_dir_p instead of comparing prompt to "Dired".
* gtkutil.c (xg_get_file_with_chooser)
(xg_get_file_with_selection): New functions, only defined ifdef
HAVE_GTK_FILE_CHOOSER_DIALOG_NEW and HAVE_GTK_FILE_SELECTION_NEW
respectively.
(xg_get_file_name): Add parameter only_dir_p.
Call xg_get_file_with_chooser or xg_get_file_with_selection
depending on HAVE_GTK_FILE* and the value of use_old_gtk_file_dialog.
(xg_initialize): New DEFVAR_BOOL use_old_gtk_file_dialog.
* gtkutil.h (xg_get_file_name): Add parameter only_dir_p.
declare and use them if NON_BLOCKING_CONNECT is defined.
(IF_NON_BLOCKING_CONNECT): New helper macro.
(wait_reading_process_output): Only declare and use local vars
Connecting and check_connect when NON_BLOCKING_CONNECT is defined.
(init_process): Initialize them if NON_BLOCKING_CONNECT defined.
tool_bar_items and assign the result to f->tool_bar_items if
not equal. Move BLOCK/UNBLOCK_INPUT from around call to
tool_bar_items to assignment of result.
