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.
