Gleb Smirnoff 1897a4f168 Fix regression from r310655, which broke operation of bsnmpd if it is bound
to a non-wildcard address.  As documented in ip(4), doing sendmsg(2) with
IP_SENDSRCADDR on a socket that is bound to non-wildcard address is
completely different to using this control message on a wildcard one.

A fix is to add a bool to mark whether we did setsockopt(IP_RECVDSTADDR)
on the socket, and use IP_SENDSRCADDR control message only if we did.

While here, garbage collect absolutely useless udp_recv() function that
establishes some structures on stack to never use them later.
