The two member functions, SetAsSortKey() and SetSortOrder(), were doing almost
the same thing but differently and the former was only used in the generic
wxDataViewCtrl implementation and not implemented in the native GTK/OS X one.
Remove SetAsSortKey() entirely and only keep UnsetAsSortKey() which is still
needed by generic/MSW wxDataViewCtrl. But only SetSortOrder() should now be
called to indicate that the column is used for sorting.

wxDataViewCtrl::GetSelection() now always returns invalid item if more than
a single item is selected in a multi-selection control.
Also add HasSelection() and GetSelectedItemsCount() to allow checking if any
items are selected.
Updated the documentation, all ports and added a test for all these functions.

Add an extremely simple RAII wrapper around GList and use it.
Also add wxGtkTreePathList which also automatically frees its contents to
simplify working with the lists of GtkTreePaths.

Existing declarations used -1 in several places to indicate the absence of the
image which wasn't especially clear and was also inconsistent with other
places that used wxNOT_FOUND which didn't make much sense in this context.
Add a new symbolic constant NO_IMAGE in wxWithImages and use it in the classes
deriving from it. This still doesn't help with wx{Tree,List}Ctrl but improves
clarity for the other classes.

IsEmpty() didn't exist in all ports (notably not wxMSW) and its meaning was
unclear anyhow, so remove it even from the ports where it did exist and add
clear Is{List,Text}Empty() replacements instead.

Implement support for wxHELP for wxMSW, wxGTK and wxOSX/Cocoa (at least when
showing the message box from the main thread, there doesn't seem to be any way
to show more than three buttons with CFUserNotificationDisplayAlert() so
"Help" button is not supported when using it).
This is useful not only on its own, i.e. to allow the user to ask for help,
but also because it brings the total number of buttons supported by the
message dialog to 4, meaning that more choices can be offered to the user
(which is rarely, but not quite never, useful).

Correctly initialize the alignment used by the text renderer used by
wxDataViewCustomRenderer in wxGTK implementation of wxDataViewCtrl.

We can't use the column pointer in wxDataViewProgressRenderer ctor as it's not
set yet, so postpone setting the renderer label until later in non-Unicode
build which needs the font used by this column to do the conversion to UTF-8.

While GTK+ doesn't support imposing ranges for dates selection natively, we
can do it ourselves by preventing the user from selecting any date outside of
the currently valid range.
This allows to use ranges under all platforms and not only in wxCalendarCtrl
itself but in wxDatePickerCtrl as well.

Introduce wxAnyButton class, a common base class for wxButton and
wxToggleButton, allowing to reuse the same implementation for them.
This also allows to implement support for bitmaps in wxToggleButton for all
platforms and make wxBitmapToggleButton a trivial subclass of it everywhere,
similarly to wxBitmapButton and wxButton.
Closes#13198.
