  Log:
  dns/dnrd: recv_addr init wrong and 512 byte udp packets dropped
  
          There are a few bugs in dnrd that should probably be fixed
          by the author but could be made to work on bsd:
  
          1.  Initialization in common.h of recv_addr is broken,
          causing at least the '-a' switch not to work.  Instead of
          assuming positions of fields in the struct across platforms
          I thought it safer to do a standard initialization in main().
  
          2.  The buffer overflow code in udp.c:dnsrecv() is off by
          one, rejecting messages where the size exactly fills the
          available buffer.  I also changed to the calls to dnsrecv
          to pass 512 as the max size instead of the buffers that
          seem to be padded by 4 bytes for a reason I don't understand.
          This causes a calling named to resend packets.  Eventually
          one seems to get through but response times can be painfully
          slow.
