Beginnings of proper SSL support.  NETLIB_SSL_SOCKET creates the unerdlying
SSL structures needed.
Build support for the new SSL interface.  The options file directly brings
in the SSL RTL.  However, this is only temporary.  In future we will
resolve these with LIB$FIND_IMAGE_SYMBOL and code around API differences
in SSL.
Added dummy DNS interface routines.
