ff653a7ef8 Call module init init again, and new function startup and destartup. 
NULL can be used if the function is not used. Open shared ports during
reload. Deinit is called during reload.

7c5e765b3b - Fix cachedb with serve-expired-client-timeout disabled. The edns 
subnet module deletes global cache and cachedb cache when it
  stores a result, and serve-expired is enabled, so that the global
  reply, that is older than the ecs reply, does not return after
  the ecs reply expires.

Serve stale (#159) 
- Added serve-stale functionality as described in
  draft-ietf-dnsop-serve-stale-10. `serve-expired-*` options can be used
  to configure the behavior.
- Updated cachedb to honor `serve-expired-ttl`; Fixes #107.
- Renamed statistic `num.zero_ttl` to `num.expired` as expired replies
  come with a configurable TTL value (`serve-expired-reply-ttl`).
- Fixed stats when replying with cached, cname-aliased records.
- Added missing default values for redis cachedb backend.
