W.C.A. Wijngaards c58e6add2b - Fix #1492 from zacek: Data race in log_init() on 
key_created/log_lock when calling ub_ctx_create()
  concurrently from multiple threads.

akhanin-dnsfandGitHub 307fc6f062 - Fix bounds check in packed_rr_to_string, it checked the (#1488) 
assembled rr length against the output string length
  dest_len, instead of against the size of the rr buffer it
  writes into. Callers in cachedump.c and remote.c pass a
  dest_len larger than that buffer.
- Unit test for packed_rr_to_string.

W.C.A. Wijngaards 79e100a7fb - Fix #1477: respip + dns64: dns64 uses A records modified by 
respip instead of original A records. Adds local-zone types
  block_a_wdata and block_aaaa_wdata, that are like block_a
  and block_aaaa, and uses local-data if present.

 		c8b3c89a39 Add new static zone type block_aaaa to suppress AAAA queries (#1433) 
Following d5b9a790f lead for block_a - this would allow suppressing AAAA queries instead for sticking to IPV4.
