Change the resolver implementation to no longer require the typedefs
InternetProtocol::resolver_query and InternetProtocol::resolver_iterator,
as neither typedef is part of the documented InternetProtocol requirements.

The following typedefs are now marked as deprecated:
- icmp::resolver_query
- icmp::resolver_iterator
- tcp::resolver_query
- tcp::resolver_iterator
- udp::resolver_query
- udp::resolver_iterator
