It turns out that GtkBuilder will sometimes set a property
twice. Normally, this is harmless, but for GtkRadioButton:group,
it triggered a critical. Remove that.
All buttons should always be marked as :active when they are pressed.
That includes checkboxes (which are never activated in real code anyway,
so this change pretty much doesn't matter).
on:
- GtkToggleButton
- GtkCheckButton
- GtkRadioButton
- GtkModelButton
- GtkCellRendererToggle
- GtkCheckMenuItem
also update themes:
- Adwaita
- Raleigh
but not the win32 theme.
The new :checked state replaces :active for the actual checkedness of
the widgets and :active is now used exclusively while the button is being
pressed.

Since constructors like gtk_radio_button_new_from_widget take an
instance of their type as the first argument, the gi scanner interprets
them as methods.
https://bugzilla.gnome.org/show_bug.cgi?id=661858
constructors which take an object of the same class as its first argument are
mis-detected as method call with "self" argument by the GIR scanner. Using the
new (constructor) annotation from bug 561264, mark some of them as proper
constuctors, so that you can call them with NULL as first argument from
bindings; in particular, this fixes gdk_window_new() and the
gtk_radio_button_new_with*() constructors.
This change does not introduce any functionality change, mostly
cosmtic cleanups, like re-linebreak when introduced annotations messed
up indentation or whitespace errors fixes.
In the current introspection data, the various gtk_radio_button_new_*
constructors take an existing group or widget. These all allow passing a NULL
widget or group list, so that it becomes easy to build a radio button list in a
loop (pass in None the first time, and the previously created button in all
other iterations).
Add the missing "allow-none" tag to the introspection data, so that this will
also eventually work for GIR users. NB that it does not actually work for some
constructors yet (like new_with_label_from_widget()) due to
https://bugzilla.gnome.org/show_bug.cgi?id=561264.
