Log Message:
Check in some long-pending tweaks from my laptop.  Implements DNS, refactors.

NetUtils (New File):
- Added new module to hold general-purpose networking code.  Currently
  includes gethostname/getaddrinfo wrappers; timeout helper code; and
  IPv6-support testing.

BuildMessage:
- Finally remove the old build*Message calls and switch to the build*Packet
  messages.  The difference is that the old ones combined payload encoding
  with packet building, while the new ones take a complete (~28K) payload
  generated by encodeMessage.

ClientDirectory:
- Debug lots of new code.
- Turn timeout from global to argument
- Use new NetUtils timeout logic.

ClientDirectory,ClientMain:
- Make DROP packets work again.

Common, MMTPClient:
- Move TimeoutError into Common

Common:
- Add function to detect strings that look like hostnames
- Debug TimeoutQueue

Config:
- Add _parseHost and _parseIP6

MMTPClient:
- Handle DNS lookup for MMTPHostInfo code and (possible) IPv6 result.
- Use new NetUtils timeout code

Packet:
- Don't allow MMTPHostInfo objects when hostname is not a possible hostname
- Force hostnames to lower case

ServerInfo, ServerKeys:
- Rename Packet-Formats to Packet-Versions
- Deprecate IP, add Hostname.
- Deprecate Key-Digest.
- Add getIP, getHostname
- Make getKeyDigest compute digest of identity key; we don't need Key-Digest
  any more.
- Refactor protocol matchup code
- Add canStartAt function to tell whether we can connect directly to a given
  server.

test:
- Add test for new packet types and config types
- Change code to use new BuildMessage interfaces

DNSFarm:
- Handle panding requests correctly.
- Move getIP functions to NetUtils.

MMTPServer,ServerMain:
- Implement DNS farm hookup for MMTPHostInfo routing.

ServerConfig:
- Add hostnames to configuration.
