Add new annotations for property accessors

We introduce two new annotations:

  - (set-property PROPERTY_NAME)
  - (get-property PROPERTY_NAME)

These annotations are valid inside function blocks for methods on
objects and interfaces, and define whether a function is a property
accessor, e.g.:

    /**
     * gtk_widget_set_name: (set-property name)
     * @self: ...
     * @name: ...
     *
     * ...
     */

    /**
     * gtk_widget_get_name: (get-property name)
     * @self: ...
     *
     * ...
     *
     * Returns: ...
     */

The annotations are transformed into the GIR data as attributes:

 - glib:set-property="PROPERTY_NAME"
 - glib:get-property="PROPERTY_NAME"

The underlying typelib data has had flags for setter and getter
functions for a while, but they have never been plugged into the GIR
data or the introspection scanner. Now they are; you can retrieve the
GIPropertyInfo from a GIFunctionInfo that has the GI_FUNCTION_IS_SETTER
or GI_FUNCTION_IS_GETTER flags set.

Fixes: #13
