Ramkumar Radhakrishnan 060e7797ed display: Add binder interface between hwcservice and its clients.
Add hwc_service.cpp and ihwc.cpp file to enable direct communication
to hwcomposer by the clients to set hwc system wide properties.

Create hwcomposer service singleton object in hwc_context_t structure.
