Bug Fixes

- In rare circumstances, named would exit with assertion failure when the number
  of nodes stored in the red-black-tree exceeds the maximum allowed size of the
  internal hashtable.  [GL #2104]

- Silence spurious system log messages for EPROTO(71) error code that has been
  seen on older operating systems where unhandled ICMPv6 errors result in a
  generic protocol error being returned instead of the more specific error code.
  [GL #1928]
