Evan Hunt 82a81287f9 Handle UDP send errors when sending DNS message larger than MTU ...

When the fragmentation is disabled on UDP sockets, the uv_udp_send()
call can fail with UV_EMSGSIZE for messages larger than path MTU.
Previously, this error would end with just discarding the response.  In
this commit, a proper handling of such case is added and on such error,
a new DNS response with truncated bit set is generated and sent to the
client.

This change allows us to disable the fragmentation on the UDP
sockets again.
