Tor 0.2.2.4-alpha released

On October 10, we released Tor version 0.2.2.4-alpha.

This release can be found at https://www.torproject.org/download/

It contains the following:
Major bugfixes:

• Fix several more asserts in the circuit_build_times code, for
  example one that causes Tor to fail to start once we have
  accumulated 5000 build times in the state file. Bugfixes on
  0.2.2.2-alpha; fixes bug 1108.

New directory authorities:

• Move moria1 and Tonga to alternate IP addresses.

Minor features:

• Log SSL state transitions at debug level during handshake, and
  include SSL states in error messages. This may help debug future
  SSL handshake issues.
• Add a new "Handshake" log domain for activities that happen
  during the TLS handshake.
• Revert to the "June 3 2009" ip-to-country file. The September one
  seems to have removed most US IP addresses.
• Directory authorities now reject Tor relays with versions less than
  0.1.2.14. This step cuts out four relays from the current network,
  none of which are very big.

Minor bugfixes:

• Fix a couple of smaller issues with gathering statistics. Bugfixes
  on 0.2.2.1-alpha.
• Fix two memory leaks in the error case of
  circuit_build_times_parse_state. Bugfix on 0.2.2.2-alpha.
• Don't count one-hop circuits when we're estimating how long it
  takes circuits to build on average. Otherwise we'll set our circuit
  build timeout lower than we should. Bugfix on 0.2.2.2-alpha.
• Directory authorities no longer change their opinion of, or vote on,
  whether a router is Running, unless they have themselves been
  online long enough to have some idea. Bugfix on 0.2.0.6-alpha.
  Fixes bug 1023.

Code simplifications and refactoring:

• Revise our unit tests to use the "tinytest" framework, so we
  can run tests in their own processes, have smarter setup/teardown
  code, and so on. The unit test code has moved to its own
  subdirectory, and has been split into multiple modules.
