1e0cf1e86b - Merge patch to fix for glue that is outside of zone, with
`harden-unverified-glue`, from Karthik Umashankar (Microsoft).
  Enabling this option protects the Unbound resolver against bad
  glue, that is unverified out of zone glue, by resolving them.
  It uses the records as last resort if there is no other working
  glue.

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.

55d8fe2837 - use a cachedb answer even if it's "expired" when serve-expired is yes
(patch from Jinmei Tatuya).
- trigger refetching of the answer in that case (this will bypass
  cachedb lookup)
- allow storing a 0-TTL answer from cachedb in the in-memory message
  cache when serve-expired is yes

c7a9776d91 - Acknowledge use of unbound-java code in iterator. Nicer readme.
- services/cache/dns.c DNS Cache. Hybrid cache uses msgcache and
         rrset cache from module environment.
       - packed rrset key has type and class as easily accessable struct
         members. They are still kept in network format for fast msg encode.
       - dns cache find_delegation routine.
