libqservice: Add a client interface.
Add a client interface which interfaces with hwc.
qservice upon receiving IPC, provides a callback notification to the qclient
which does appropriate stuff in hwc.
In future, qservice can safely be even made a separate process with no changes
to exisiting code. This was not true earlier owing to the hwc pointer held by
qservice forcing it to be in the same process that hwc is in.
