Patchset:

PS1: FYI: All users of SCCP UNIT-DATA.req (through osmo_sccp_tx_unitdata(_msg)()) are using it to send RESET/RESET-ACK and PAGING messages, so it's fine to set the OSMO_SCU_UNITDATA_REQ_P_SEQUENCE_CONTROL_NOT_PRESENT in osmo_sccp_tx_unitdata() so they end up as ProtoClass 0 imho.

I used the NOT_PRESENT define in order to avoid breaking ABI, let me know if you think I should be adding a "bool in_seq_control_present" instead.
