4c150d8eb5 The big versioning cleanup
Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.

c655759cef Replace gdk_threads_add_timeout* with g_timeout_add()
The main GDK thread lock is not portable and deprecated.

The only reason why gdk_threads_add_timeout() and
gdk_threads_add_timeout_full() exist is to allow invoking a callback
with the GDK lock held, in case 3rd party libraries still use the
deprecated gdk_threads_enter()/gdk_threads_leave() API.

Since we're removing the GDK lock, and we're releasing a new major API,
such code cannot exist any more; this means we can use the GLib API for
installing timeout callbacks.

f824439137 dnd: Get rid of IPC widgets
Instead, pass the source window to gdk_drag_begin().

Also make Wayland use this window instead of the one under the pointer
(though those 2 Windows are most likely the same anyway).

8f6194a883 dnd: Remove unused function
The function was referencing itself in ways that bamboozled gcc:
  static void
  foo (void)
  {
    g_signal_handlers_disconnect_by_func (NULL, foo, NULL);
  }

Well done, function, you get your own commit!

b49a9b9933 dnd: Remove gdk_drag_get_selection()
Without selections, drags can't have them either.

Also included is removing the selection from GtkSelectionData.

Includes a bunch of crude cleanups to Wayland code that no longer has to
care about selection atoms.

8648d5409e dnd: Pass content to gdk_drag_begin()
Instead of just passing the GdkContentFormats, we are now passing the
GdkContentProvider to gdk_drag_begin().
This means that GDK itself can now query the data from the provider
directly instead of having to send selection events.

Use this to provide the private API gdk_drag_context_write() that allows
backends to pass an output stream that this data will be written to.
Implement this as the mechanism for providing drag data on Wayland.

And to make this all work, implement a content provider named
GtkDragContent that is implemented by reverting to the old DND
drag-data-get machinery inside GTK, so for widgets everything works just
like before.

803cbd576f dnd: Introduce gdk_drop_read_async() and use it
This is the replacement for selection usage.

Backend implementations for X11 (missing support for backwards compat

GTK code should be adapted to use gdk_drop_read_*() functions instead
of gtk_drag_get_data().

6c29e81051 W32: Massive W32 DnD fix
Massive changes to OLE2 DnD protocol, which was completely broken before:
* Keep GdkDragContext and OLE2 objects separate (don't ref/unref them
  together, don't necessarily create them together).
* Keep IDataObject formats in the object itself, not in a global variable.
* Fix getdata() to look up the request target in its format list, not in the
  global hash table
* Create target GdkDragContext on each drag_enter, destroy it on drag_leave,
  whereas IDropTarget is created when a window becomes a drag destination
  and is re-used indefinitely.
* Query the source IDataObject for its supported types, cache them in the
  target (!) context. This is how GTK+ works, honestly.
* Remember current_src_object when we initiate a drag, to be able
  to detect later on that the data object is ours and use a
  shortcut when querying targets
* Make sure GDK_DRAG_MOTION is only sent when something changes
* Support GTK drag cursors
* Ensure that exotic GTK clipboard formats are registered
  (but try to avoid registering formats that can't be used between applications).
* Don't enumerate internal formats
* Ensure that DnD indicator window can't accept drags or receive any kind of input
  (use WS_EX_TRANSPARENT).
* Remove unneeded indentation in _gdk_win32_dnd_do_dragdrop()
* Fix indentation in gdk_win32_drag_context_drop_finish()
* Remove obsolete comments in _gdk_win32_window_register_dnd()
* Check for DnD in progress when processing WM_KILLFOCUS, don't emit a grab
  break event in such cases (this allows alt-tabbing while DnD is in progress,
  though there may be lingering issues with focus after dropping...)
* Support Shell ID List -> text/uri-list conversion, now it's possible
  to drop files (dragged from Explorer) on GTK+ applications
* Explicitly use RegisterClipboardFormatA() when we know that the string
  is not in unicode. Otherwise explicitly use RegisterClipboardFormatW()
  with a UTF8->UTF16 converted string
* Fix _gdk_win32_display_get_selection_owner() to correctly bail
  when selection owner HWND is NULL (looking up GdkWindow for NULL
  HWND always succeeds and returns the root window - not the intended
  effect)
* More logging
* Send DROP_FINISHED event after DnD loop ends
* Send STATUS event on feedback
* Move GetKeyboardState() and related code into _gdk_win32_window_drag_begin(),
  so that it's closer to the point where last_pt and start_pt are set
* Use & 0x80 to check for the key being pressed. Windows will set low-order bit
  to 1 for all mouse buttons to indicate that they are toggled, so simply
  checking for the value not being 0 is not enough anymore.
  This is probably a new thing in modern W32 that didn't exist before
  (OLE2 DnD code is old).
* Fixed (hopefully) and simplified HiDPI parts of the code.

Also adds managed DnD implementation for W32 GDK backend (for both
OLE2 and LOCAL protocols). Mostly a copy of the X11 backend code, but
there are some minor differences:
* doesn't use drag_window field in GdkDragContext,
  uses the one in GdkWin32DragContext exclusively
* subtracts hotspot offset from the window coordinates when showing
  the dragback animation
* tries to consistently support scaling and caches the scale
  in the context
* Some keynav code is removed (places where grabbing/ungrabbing should
  happen is marked with TODOs), and the rest is probably inert.

Also significantly changes the way selection (and clipboard) is handled
(as MSDN rightly notes, the handling for DnD and Clipboard
 formats is virtually the same, so it makes sense to handle
 both with the same code):
* Don't spam GDK_OWNER_CHANGE, send them only when owner
  actually changes
* Open clipboard when our process becomes the clipboard owner
  (we are doing it anyway, to empty the clipboard and *become* the owner),
  and then don't close it until a scheduled selection request event
  (with TARGETS target) is received. Process that event by announcing
  all of our supported formats (by that time add_targets() should have
  been called up the stack, thus the formats are known; just in case,
  add_targets() will also schedule a selection request, if one isn't
  scheduled already, so that late-coming formats can still be announced).
* Allow clipboard opening for selection_convert() to be delayed if it
  fails initially.
* The last two points above should fix all the bugs about GTK+ rising
  too much ruckus over OpenClipboard() failures, as owner change
  *is allowed* to fail (though not all callers currently handle
  that case), and selection_convert() is asynchronous to begin with.
  Still, this is somewhat risky, as there's a possibility that the
  code will work in unexpected ways and the clipboard will remain open.
  There's now logging to track the clipboard being opened and closed,
  and a number of failsafes that try to ensure that it isn't kept open
  for no reason.
* Added copious notes on the way clipboard works on X11, Windows and GDK-W32,
  also removed old comments in DnD implementation, replaced some of them
  with the new ones
* A lot of crufty module-global variables are stuffed into a singleton
  object, GdkWin32Selection. It's technically possible to make it a
  sub-object of the Display object (the way Wayland backend does),
  but since Display object on W32 is a singleton anyway... why bother?
* Fixed the send_change_events() a bit (was slightly broken in one of the
  previous iterations)
* Ensure that there's no confusion between selection conversion (an artifact
  term from X11) and selection transmutation (changing the data to be W32-compatible)
* Put all the transmutation code and format-target-matching code into gdkselection-win32.c,
  now this code isn't spread across multiple files.
* Consequently, moved some code away from gdkproperty-win32.c and gdkdnd-win32.c
* Extensive format transmutation checks for OLE2 DnD and clipboard.
  We now keep track of which format mappings are for transmutations,
  and which aren't (for example, when formats are passed as-is, or when
  a registered name is just an alias)
* Put transmutation code into separate functions

* Ensure that drop target keeps a format->target map for supported formats,
  this is useful when selection_convert() is called, as it only receives a
  single target and no hints on the format from which the data should
  be transmuted into this target.
* Add clear_targets() on W32, to de called by GTK
* Use g_set_object() instead of g_ref_object() where it is allowed.
* Fix indentation (and convert tabs to spaces), remove unused variables

1a70ca75e8 gdk: Sanitize GdkContentFormats API
Make sure the API reflects the idea that GdkContentFormats is a set
containing mime types. In particular, treat the object itself as a
plural - it's named content format`S' after all - and therefor use
the correct verb form.

Also make GdkContentFormats keep an array instead of a list, now that
it's immutable.

3f5178dc21 selection: Remove the info uint
Instead of allowing people to pass a uint user-data, insist on them

The user data was a uint instead of a pointer anyway, so uniqueness

And that's ignoring the fact that it basically wasn't used.
