0d293533f5 Added OpenSSL-like HMAC API using Apple 
CommonCrypto as backend.

7dd61393ab Move crypto random number headers out of openvpn/openssl 
into openvpn/random.  Also move boostrand.hpp into
openvpn/random.

6fcd683d46 Added align_block parameter to Frame::Context, since align_block isn't 
necessarily going to always be sizeof(size_t).  In some cases, we might
want it to be the cipher block size.

f09b9ae12a Added reltest.cpp for testing ReliableRecv and ReliableSend 
objects by simulating an unreliable packet stream.

Modified packet_id code so that current time (now) is passed
via function calls rather than accessed as a global.

Added integer random number support via boost::random.

931a4b1a07 In Cleartun, revert to single-threaded mode only regardless of whether 
Boost/Asio built in single-threaded mode.  This is done due to the
revelation that Asio socket objects are not thread-safe.

Break out IOStats into two classes:

* IOStatsSingleThread
* IOStatsMultiThread
