Yawning Angel 9bfdd77f72 Add preliminary support for packet length obfuscation. 
The same algorithm as ScrambleSuit is used, except:
 * SipHash-2-4 in OFB mode is used to create the distribution.
 * The system CSPRNG is used when sampling the distribution.

This fixes most of #3, all that remains is generating and sending a
persistent distribution on the server side to the client.

Yawning Angel 06a95ff1e0 Close connections that fail to authenticate after a while. 
Like ScrambleSuit, a random interval between 1x and 5x of additional
data from the peer is read and immediately discarded before closing.

Additionally, obfs4 will close off invalid connections anywhere between
0 and 60 seconds after it determines that the incoming connection will
never complete the handshake successfully.
