dnsext-*

This is a new series of DNS libraries based on the experience of the dns library in Haskell. The dns library has two flaws:

• Resource records are not extensible
• Resource records are not friendly to caching

Resource records are implemented as a sum type. The third party library cannot extend them. The only way to extend them is to send a pull request to the dns library.

Some resource records use ByteString internally. So, if they are cached for a long time, fragmentation happens.

This new library uses typeclasses to extend resource records and uses ShortByteString in them.
