a113ac0506 Rework the way we enable CTL iSCSI port. Previously conf_apply() 
needed it to be already enabled, because listening in proxy mode
requires it; however, it's conf_apply() that opens pidfiles,
so it resulted in port being enabled before pidfile was opened.
This was not so bad, but it was also disabled when pidfile couldn't
be opened due to ctld already running; this means that starting
second ctld instance screwed up the first.

8cab2ed4cd Properly identify target portal when running in proxy mode. While here, 
remove CTL_ISCSI_CLOSE, it wasn't used or implemented anyway.

ba3a2d31c8 Make it possible for the iSCSI target side to operate in both normal 
and ICL_KERNEL_PROXY mode, and fix some bit rot so the latter actually
works again.

70b939ecd3 So, it turns out SIGCHLD is discarded by default, so we have to set up 
a dummy handler to make it interrupt an ioctl(2) or select(2).

This makes those short-lived ctld(8) zombies disappear.

e76ce4484d Use new auth-type "deny" instead of using "chap" with no chap entries; 
it's cleaner this way, and gives better feedback to the user.

ccb1f04d95 Use "default" as default discovery-auth-group, instead of "no-access". 
It doesn't change visible behaviour, as previously auth-group "default"
wasn't redefinable, so by default access was always denied.

7843bd031a Fix several problems in the new iSCSI stack; this includes interoperability 
fix for LIO (Linux target), removing possibility for the target to avoid mutual
CHAP by choosing to skip authentication altogether, and fixing truncated error
messages in iscsictl(8) output.  This also fixes several of the problems found
with Coverity.

Note that this change requires world rebuild.
