[M] Change in ...osmo-epdg[master]: Split auth_handler module into SWm files for ePDG and AAA Server

by pespin

pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/erlang/osmo-epdg/+/35689?usp=email ) Change subject: Split auth_handler module into SWm files for ePDG and AAA Server ...................................................................... Split auth_handler module into SWm files for ePDG and AAA Server This allows more easily matching and following the code against the procedures the specs define. Also, ensure proper separation of data and proper order of procedures when later on we may split the AAA Server to be an external process.
