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. git-svn-id: https://unbound.nlnetlabs.nl/svn/trunk@3947 be551aaa-1e26-0410-a405-d3ace91eadb9
