d48abb9a84 clang analysis fixes, assert arc4random buffer in init, 
no check for already checked delegation pointer in iterator,
in testcode check for NULL packet matches, in perf do not copy
from NULL start list when growing capacity.  Adjust host and file
only when present in test header read to please checker.  In
testcode for unknown macro operand give zero result. Initialise the
passed argv array in test code.  In test code add EDNS data
segment copy only when nonempty.

9b6caf5a5b - Fix that with harden-below-nxdomain and qname minisation enabled 
some iterator states for nonresponsive domains can get into a
  state where they waited for an empty list.
- Stop UDP to TCP failover after timeouts that causes the ping count
  to be reset by the TCP time measurement (that exists for TLS),
  because that causes the UDP part to not be measured as timeout.

7b948b0647 - Added generic EDNS code for registering known EDNS option codes, 
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.
