GTK+ applications will provide accessibility support over this dbus
service, so the AT-SPI clients (screen reader etc.) could use them.

And this 'org.a11y.Bus' service can be auto activated by the dbus
session daemon if the 'at-spi2-core' package is available.  If not,
we'll get thoese warnning from applications.

Usually they're harmless, and can be suppressed by set the environment
variable 'NO_AT_BRIGE=1'.
