I would suggest renaming 'conn_id' to 'link_id' to be more aligned with the
spec. The same remark applies to 'msg_num' - it's called 'transaction
number' in the standard.

This change requires updating the callers to add the 'initiator'
argument. I think this should be:
prov-initiator.c, initiator_start():
/* Always register for PB-ADV */
result = pb_adv_reg(true, int_prov_open, int_prov_close, int_prov_rx,
int_prov_ack, uuid, prov);
prov-acceptor.c, acceptor_start():
/* Always register for PB-ADV */
result = pb_adv_reg(false, acp_prov_open, acp_prov_close, acp_prov_rx,
acp_prov_ack, uuid, prov);
