After some digging up on the get_ME_state double definition, it seems that it's come from so3/include/log.h which include soo/soo.h and soo/dev/vlogs.h if CONFIG_SOO is defined. As vlogs is only used for the logs when CONFIG_VLOGS_FRONTEND is defined, the ifdef can be changed to use it, fixing issue with multiple definition of get_ME_state.

In any case, I still think it's a good idea to rename the get_ME_state in avz to differentiate from the one in SOO. As well for the set_ME_state which take the slot ID too in avz. Maybe, instead of avz_get_ME_state we could name it get_ME_slot_state ?
