Commit Message

DNS Record Write (#598)

The `ares_dns_record_t` data structure created in the prior release is capable of holding a complete parsed DNS message and also provides all helpers in order to fill in the data structure.  This PR adds write capabilities for this data structure to form a complete message and supports features such as DNS name compression as defined in RFC1035.  Though this message writing capability goes further than c-ares internally needs, external users may find it useful ... and we may find it useful for test validation as well.

This also replaces the existing message writing code in `ares_create_query()`, as well rewriting the request message without EDNS in ares_process.c's `process_answer()`.
