(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

bypassing the cache response stage and uniquifying mesh states. Four EDNS
option lists were added to module_qstate (module_qstate.edns_opts_*) to
store EDNS options from/to front/back side.
- Added two flags to module_qstate (no_cache_lookup, no_cache_store) that
control the modules' cache interactions.
- Added code for registering inplace callback functions. The registered
functions can be called just before replying with local data or Chaos,
replying from cache, replying with SERVFAIL, replying with a resolved
query, sending a query to a nameserver. The functions can inspect the
available data and maybe change response/query related data (i.e. append
EDNS options).
- Updated Python module for the above.
- Updated Python documentation.

after parse use edns_opt_find(edns.opt_list, LDNS_EDNS_NSID),
to insert use edns_opt_append(edns, region, code, len, bindata) on
the opt_list passed to send_query, or in edns_opt_inplace_reply.

assertions in mesh.c resist duplicates. Fixes DS NS search to
not generate duplicate sub queries.

resumed that then fails and sends an error message. (Thanks to

- queries with CD flag set cause DNSSEC validation, but the answer is
not withheld if it is bogus. Thus, unbound will retry if it is bad
and curb the TTL if it is bad, thus protecting the cache for use by
downstream validators.

in overload situations to be about 5 qps for the class of shortly
serviced queries.
The capacity of the resolver is then about (numqueriesperthread / 2)
/ (average time for such long queries) qps for long queries.
And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
qps for short queries, per thread.
