OCaml implementation of the DNS protocol

This is a pure OCaml implementation of the DNS protocol. It is intended to be a reasonably high-performance implementation, but clarity is preferred rather than low-level performance hacks.

To build it, the following packages are required:

• OCaml 4.00.1 or higher.
• Lwt 2.3.2 or higher: http://ocsigen.org/lwt/
• Cstruct: http://github.com/mirage/ocaml-cstruct
• Re: http://github.com/mirage/ocaml-re

Packages:

• lib/ contains the core DNS protocol, which is packed into the Dns module.
• lib_test/ contains unit tests and sample uses of the library. In particular, time_server is a simple dynamic responder.

Areas that need work:

• We need a Lwt-based client resolver, preferably both recursive and iterative. Patches for this are highly welcome!
• EDNS0 extensions.
• DNSSEC extensions (using Cryptokit).
