Change subject: api doc: auth_core.c: add \returns, cosmetic ...................................................................... api doc: auth_core.c: add \returns, cosmetic Add various missing \returns doxygen entries. In osmo_auth_3g_from_2g(), also adjust two comment-closing instances to match common style and add a period to end a sentence. (The recent addition of osmo_auth_3g_from_2g() raised my attention, and I added more return value docs while at it.)
