the right way.

be implemented.

The rest of this change mostly contains random ideas taken from
mod_ssl.  The purpose is to get the repository in sync with the
code I am testing.  I still can't manage to make Netscape send
its certificate to slapd, though it works with Apache/mod_ssl
(with the same certificates).  Trying s_client against both
does not shed any light.  If anyone manages to make it work,
please let us know.

Let transport (TLS or somesuch) force reading or writing on
sockets even if the higher layers think otherwise.

to exhaust all protocol units received from the transport layer.
I think this is the necessary fix for the TLS-data-ready/
socket-not-ready issue, but I have not experimented that problem
yet, so I am unsure about its effectiveness.
Now, do we need something like that for connection_write?  How would
we go about implementing it?

connection_init so that we get into the select() logic.
Make use of new flags in the connection.
BTW, and before I forget, it sort of works.  I have connected with
a Netscape client using a secure connection and did a failed
search (my test database is empty), but the trace looked correct.
Make sure you have your CA certificate in your Netscape preinstalled.
Otherwise, the connection fails with error 0xFFFFFFFF that is rather
uninformative.

Set flags without relying on errno (this change may be gratuitous
or wrong).

do SSL_accept on this connection.
