Are you sure that it is a good idea to move the check of port->noblock
out of be_tls_[read|write] to an upper level? ISTM that we should set
errno and n to respectively EWOULDBLOCK and -1 in be_tls_[write|read]
when port->noblock and do nothing otherwise. In your patch those
values are set even if the port is in block mode.
