This adds the glue to allocate TLS sessions and invokes it from the TLS enable socket option handler. This also adds some counters for active TOE sessions. The TOE KTLS mode is returned by getsockopt(TLSTX_TLS_MODE) when TOE KTLS is in use on a socket, but cannot be set via setsockopt(). To simplify various checks, a TLS session now includes an explicit 'mode' member set to the value returned by TLSTX_TLS_MODE. Various places that used to check 'sw_encrypt' against NULL to determine software vs ifnet (NIC) TLS now check 'mode' instead.
