From 203a3df5a239d644cf42b7bac03a268eb5babfc7 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] Initial version of ibus portal
This adds a dbus service called org.freedesktop.portal.IBus on the
session bus. It is a very limited service that only implements
CreateInputContext and the InputContext interface (and Service.Destroy
for lifetime access).
It uses gdbus code generation for demarshalling the method calls which
means it will verify that all arguments have the right type.
Additionally all method calls to the input context object have to be
from the client that created it, so each client is isolated.
