[M] Change in libosmo-sigtran[master]: WIP: m3ua: Make sure MTP-PAUSE.ind is sent to SCCP when AS goes down

by pespin

pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmo-sigtran/+/40488?usp=email ) Change subject: WIP: m3ua: Make sure MTP-PAUSE.ind is sent to SCCP when AS goes down ...................................................................... WIP: m3ua: Make sure MTP-PAUSE.ind is sent to SCCP when AS goes down Whenever an SCTP link goes down, it may affect current set of accessible DPCs if any of the routes (AS) using that ASP become inactive. The approach presented in this patch is to, based on existing route table, figure out which DPCs may have been accessible before the AS went down, and then figure out which of those are not reachable anymore, then send MTP-PAUSE.ind for those. In turn, SCCP will trigger N-PCSTATE.ind towards its users.
