[MEDIUM] Fix memory freeing at exit

New functions implemented:
 - deinit_pollers: called at the end of deinit())
 - prune_acl: called via list_for_each_entry_safe

Add missing pool_destroy2 calls:
 - p->hdr_idx_pool
 - pool2_tree64

Implement all task stopping:
 - health-check: needs new "struct task" in the struct server
 - queue processing: queue_mgt
 - appsess_refresh: appsession_refresh

Still not perfect but significant improvement.
