Re: protocol: closing SASL upon Unbind

Unless there are further issues with this, I will replace the current
instructions for Unbind with Kurts suggested text here.

My previous suggestion does not adequately cover the
issue of graceful closure of the LDAP session. That is,
the reason why a particular order was suggested was that
it was thought to be graceful. So while I have no
problem with removing the ordering aspect of the current
text, I'd like to indicate that Unbind/Notice of Disconnect
are intended to affect a graceful closure.

Hence, I suggest:

The client, upon transmission of the UnbindRequest, and
the server, upon receipt of the UnbindRequest are to
gracefully close the LDAP session by ceasing exchange
at the LDAP message layer, tearing down any SASL layer,
tearing down any TLS layer, and closing the transport
connection.

I note that while the 4 actions the implementation might need
to take are stated in the order which the implementation likely
would need to affect graceful closure of the LDAP session,
the text does not actually prescribe a particular order, nor
does it imply that any exchange within the SASL and/or TLS
layer would been necessary.
