As seen before, server's addr and svc_port should not be updated directly
during runtime, because even if the update is performed under the lock,
some competing threads might be reading ->addr and ->svc_port without
the lock because they simply cannot afford it.
To prevent races with such competing threads, server's addr and port
should only be updated using server_set_inetaddr() function or similar.
This patch depends on:
- "MINOR: server: ensure connection cleanup on server addr changes"
- "CLEANUP: server/event_hdl: remove purge_conn hint in INETADDR event"
- "MEDIUM: server: merge srv_update_addr() and srv_update_addr_port() logic"
- "MEDIUM: server: make server_set_inetaddr() updater serializable"
- "MINOR: server/event_hdl: expose updater info through INETADDR event"
- "MINOR: server: add dns hint in server_inetaddr_updater struct"
- "MEDIUM: server/dns: clear RMAINT when addr resolves again"
While it could be backported in 2.9 with
