Ondřej Surý eec30c33c2 Don't enable SO_REUSEADDR on outgoing UDP sockets 
Currently, the outgoing UDP sockets have enabled
SO_REUSEADDR (SO_REUSEPORT on BSDs) which allows multiple UDP sockets to
bind to the same address+port.  There's one caveat though - only a
single (the last one) socket is going to receive all the incoming
traffic.  This in turn could lead to incoming DNS message matching to
invalid dns_dispatch and getting dropped.

Disable setting the SO_REUSEADDR on the outgoing UDP sockets.  This
needs to be done explicitly because `uv_udp_open()` silently enables the
option on the socket.
