Edwin Groothuis c90d26d28b 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.
