New input method protocol for use with Qt clients

We introduce an alternative input-method protocol, which
is a one-to-one mapping to Qt's input method API. Input
methods such as the virtual keyboard's hunspell
integration is quite sensitive to the inner workings of
the input method handling, both in terms of when state
is updated and which updates are delivered when.

With a one-to-one mapping we are able to match these
expectations and keep a well-synchronized state.
