Redefine TCP state to include "flags that have been sent" rather than
...
"flags that are currently being sent". This allows at least one special
case (checking that we haven't already sent a FIN in tcp_rx_fin()) to be
collapsed.

When login fails, leave the session open but not in full feature

phase. In iscsi_issue(), detect this state and immediately refuse the
operation. This avoids trying multiple logins when scsi.c tries
several times to read the drive capacity.

A cleaner method of handling login redirection; just use the existing

We don't actually have a stdio.h header file. Our printf() functions are

defined in vsprintf.h. (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)
There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.
