Yawning Angel b3f0f51775 Move utils.go to csrand/csrand.go, and clean up the interface. 
All of the obfs4 code except unit tests now uses the csrand wrapper
routines.

Yawning Angel 272fb852e7 Change the maximm handshake length to 8192 bytes. 
* handhake_ntor_test now is considerably more comprehensive.
 * The padding related constants in the spec were clarified.

This breaks wireprotocol compatibility.

Yawning Angel fd4e3c7c74 Add replay detection to handshakes. 
This is done by maintaining a map keyed off the SipHash-2-4 digest of
the MAC_C component of the handshake.  Collisions, while possible are
unlikely in the extreme and are thus treated as replays.

In concept this is fairly similar to the ScrambleSuit `replay.py` code,
with a few modifications:

 * There is a upper bound on how large the replay filter can grow.
   Currently this is set to 102400 entries, though it is unlikely that
   this limit will be hit.

 * A doubly linked list is also maintained parallel to the map, so the
   filter compaction process does not need to iterate over the entire
   filter.
