WIP: Develop oriecpriupdates

Makes IF5 functionality compatible with ECPRI user-plane. Control-plane functionality for supporting third-party RRUs : provides an interface converting OAI-native RF parameters, a subset of LTE framing parameters, and RF streaming activation/deactivation to a wrapper (libthirdparty_transpro.so) which uses the proprietary interface of the RRU. This branch was tested with a commercial eCPRI RRU from AW2S.
