[M] Change in osmo-hnbgw[master]: immediately SCCP RLSD on HNB re-register

Attention is currently required from: laforge, pespin. Hello Jenkins Builder, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-hnbgw/+/32915 to look at the new patch set (#3). Change subject: immediately SCCP RLSD on HNB re-register ...................................................................... immediately SCCP RLSD on HNB re-register The RUA side may disconnect a) gracefully (RUA Disconnect with RANAP IU Release Complete) or b) by detecting that the HNB is gone / has restarted For a), the SCCP side waits for a RLSD from the CN that follows the IU Release Complete. For b), we so far also wait for a RLSD from CN, which will never come, and only after a timeout send an SCCP RLSD to the CN. Instead, for b), immediately send an SCCP RLSD. To distinguish between the graceful release (a) and the disruptive release (b), add new state MAP_RUA_ST_DISRUPTED on the RUA side, and add new event MAP_SCCP_EV_RAN_LINK_LOST for the SCCP side. Any non-graceful disconnect of RUA enters ST_DISRUPTED. disrupted_onenter() dispatches EV_RAN_LINK_LOST to SCCP, and SCCP directly sends RLSD to the CN without timeout. These changes are also shown in doc/charts/hnbgw_context_map.msc.
