Garbage collect s->internal->type

This variable is used in the legacy stack to decide whether we are
a server or a client. That's what s->server is for...

The new TLSv1.3 stack failed to set s->internal->type, which resulted
in hilarious mishandling of previous_{client,server}_finished. Indeed,
both client and server would first store the client's verify_data in
previous_server_finished and later overwrite it with the server's
verify_data. Consequently, renegotiation has been completely broken
for more than a year. In fact, server side renegotiation was broken
during the 6.5 release cycle. Clearly, no-one uses this.

This commit fixes client side renegotiation and restores the previous
behavior of SSL_get_client_CA_list(). Server side renegotiation will
be fixed in a later commit.
