Unify handles allocation for initiator and target IOCBs.

I am not sure why this was split long ago, but I see no reason for it.
At this point this unification just slightly reduces memory usage, but
as next step I plan to reuse shared handle space for other IOCB types.

Some polishing for command timeouts handling.

This includes the pluggable TCP framework and other chnages to the
netstack to track for VNET stability.

Fix target mode support for Qlogic 2200 FC adapters.

Now target mode works for all supported FC adapters except ancient 2100,
which is not tested.

Rip off target mode support for parallel SCSI QLogic adapters.

Hacks to enable target mode there complicated code, while didn't really
work. And for outdated hardware fixing it is not really interesting.

Initiator mode tested with Qlogic 1080 adapter is still working fine.

Generate fake ISPASYNC_CHANGE_PDB on fake login on pre-24xx.

This makes port scanner fix absent port ID for added initiator.

For those chips we are not receiving login events, adding initiators

Fix target mode with fabric for pre-24xx chips.

For those chips we are not receiving login events, adding initiators
based on ATIO requests. But there is no port ID in that structure, so
in fabric mode we have to explicitly fetch it from firmware to be able
to do normal scan after that.

Another round of port scanner rewrite.

This change simplifies and unifies port adding/updating for loop and
fabric scanners. It also fixes problems with scanning restarts due to
concurrent port databases changes. It also fixes many cosmetic issues.

Remove some confusions between loopid and nphdl.

Modern cards in most cases operate abstract port handles, that have no
any relation to real loop IDs. Leave loopid used only where it really
goes about local loop IDs.

While there, fix few more cases where LUNs were still printed in decimal.

Change the way how target mode is enabled on 23xx chips.

Without docs I am not completely sure about this, but on my tests new
method works better then previous, at least with our latest firmware.

Remove ISP_INTERNAL_TARGET code.

We have CTL now, which is real and much more functional then this joke.
