Add SSL support for Windows client and broker per QPID-1403. Adds new AsynchIO::BufferBase::squish() method that does what used to be done by in-place memmove() calls so it can be reused easily.

SSL support for Windows is in:
- Client: qpid/client/windows/SslConnector.cpp
          qpid/client/TCPConnector.{h cpp} rearranged a bit to make pieces available to SslConnector
- Broker: qpid/broker/windows/SslProtocolFactory.cpp
- Common: qpid/sys/windows/SslAsynchIO contains all the Schannel stuff to negotiate a session, encrypt, and decrypt data. The SslAsynchIO acts as a shim between the layer above and the "regular" AsynchIO that actually handles read/write and completions.
