Description

osmo-bts fails to log properly name string of NM_MT_IPACC_SET_ATTR_ACK in oml_mo_send_msg():

    DEBUGPFOH(DOML, foh, "Tx %s\n", get_value_string(abis_nm_msgtype_names, foh->msg_type));

This is because IPACCESS specific messages (enum abis_nm_msgtype_ipacc) are not included in "abis_nm_msgtype_names".

We need to discuss whether we want them added to "abis_nm_msgtype_names" or have some way to also translate those.
The problem is that there can be other vendors providing other extensions which may reuse same enum values, such as enum abis_nm_msgtype_bs11.
So ideally we should add a function to first check abis_nm_msgtype_names() and if it fails (or within expected range for vendor-implementation) then translte from "enum abis_nm_msgtype_ipacc".
