What's new in at-spi2-core 2.3.5:

* Fix for BGO#668334: Set correct end offset in atspi_text_get_attributes.

* Add some type checking on method replies; this should prevent crashes if
  an application-side AT-SPI implementor returns something unexpected.

* Call g_settings_sync after updating toolkit-accessibility.

* Add ScreenReaderEnabled D-Bus property as a proxy for the GSettings key.

* Fix for BGO#669344: Don't use "restrict" as a variable name, since it can
  be a keyword.
