Kevin Chen 3924f78748 Several serve-stale improvements ... Commit a83c8cb0af updated masterdump so that stale records in "rndc dumpdb" output no longer shows 0 TTLs. In this commit we change the name of the `rdataset->stale_ttl` field to `rdataset->expired` to make its purpose clearer, and set it to zero in cases where it's unused. Add 'rbtdb->serve_stale_ttl' to various checks so that stale records are not purged from the cache when they've been stale for RBTDB_VIRTUAL (300) seconds. Increment 'ns_statscounter_usedstale' when a stale answer is used. Note: There was a question of whether 'overmem_purge' should be purging ancient records, instead of stale ones. It is left as purging stale records, since stale records could take up the majority of the cache. This submission is copyrighted Akamai Technologies, Inc. and provided under an MPL 2.0 license.
