Update the winverbs interface and library to add support for connection

Update the winverbs interface and library to add support for connection
establishment.  The implementation supports XP, 2003, and 2008.  Because
kernel support for IP is lacking in XP and 2003, the winverbs userspace
library performs address and route resolution, rather than relying on the
kernel driver to perform those operations.

The interface for datagram support was updated to match that used for
connections, but datagram support is not implemented at this time.
