New option "-crlf" to s_client and s_server which tells them to convert

LFs into CRLFs when forwarding data from stdin to the TLS connection.
This is necessary for properly talking HTTP.
Because of the code freeze this change is by default disabled for now;
without -DAPPS_CRLF, the code is exactly as before.
