750f46d1aa - Small fixes for #41: changelog, conflicts resolved,
processQueryResponse takes an iterator env argument like other
  functions in the iterator, no colon in string for set_option,
  and some whitespace style, to make it similar to the rest.

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.
