espconn lwip wrappers actively harmful

As far as I can tell, anyway, these things are just obstruction, rather than abstraction, over lwip. See, for example, the damage they cause with #2987: it is neither obvious nor documented that espconn_gethostbyname passes the espconn structure as the callback argument. We should just be calling dns_gethostbyname ourselves and passing the appropriate lua object to the callback.

Am I missing something and espconn is actually useful? If not, I think I will propose that we attempt to excise it from our tree.

Still true, sadly.
