ASACORE-1025 Allow cleanup of Winsock API

We'd like to be able to cleanly unload AJ code from Windows (service)
process. Currently the utility function WinsockCheck is calling WSAStartup,
but there is no place that calls WSACleanup.

This change moves WinsockCheck into utility.cc as well as adds ability
to clean up Winsock API via a new function called WinsockCleanup.
