Joel Cunningham 6af3b4accc netconn: Add LWIP_HOOK_NETCONN_EXTERNAL_RESOLVE (patch #9427) ...

This adds a new hook allowing an external DNS resolver to be hooked into
netconn_gethostbyname(). The hook can handle some or all of the queries

One use case for this hook is to run mDNSResponder in the same system as LwIP
(mDNSResponder also uses LwIP's socekt APIs) and have it handle .local queries
while LwIP stack handles unicast DNS queries
