Don't check for NULL before free()

Extend the connection and session FSMs so that connection failure is
handled more gracefully. Losing the TCP connection no longer results
in an unrecoverable stop requiring a restart of iscsid.

After doing all of the loging dance to get the target's params it makes
sense to merge them into the active set. At least that way we run with
the right params and finally do reads and writes that are > 8k.

Move session params initialization to when we start a session and not
when it is created. That way the config params from the config file have
a chance to stick.

Massive diff to handle logins more correctly. iscsid will now do
better operational parameter negotiation but more is needed.
Tested by todd@ and myself.

Rework the logout code and use this to do a proper logout when
exiting. This works well for idle sessions but still has some
issues on busy session. It seems more task scheduler changes are
needed to make this work. This also includes some mem-leak fixes
in error pathes found by Igor Zinovik.

Start implementing the FSM. Introduce a session FSM that is run via a
callback and implement some of the connection FSM actions. Implement
logouts so that discovery sessions do a nice login -> query -> logout.
Fix the task scheduling especially for immediate and connection specific
tasks. The session will now only schedule tasks to a session that is
in LOGGED_IN state.
looks good dlg@

Move session related code into session.c.
