* Add Diameter Dictionary Elements
* Initial IDR Framework
* Resolve Compile Issues
* Moving Closer
* Compile error
* Somewhat Working stuffing Code
* Add Timestamp Changes
* Cleanup some of this code. mme_s6a_handle_idr in s6a-handler.c removed for now, since it will only come in handy when IDR flag is set to request current location, which would involve breaking out into paging. I think there's a few other things we can do just within fd-path first.
* further removal of mme_s6a_handle_idr
