Add network QoS support for PCP to iscsi target.

Mak the Ethernet PCP codepoint configurable
for L2 local traffic, to allow lower latency for
iSCSI block IO. This addresses the target
side only.

ctl.conf(5): fix LUN size in UCL format example.

Remove quotes around size in the LUN section and change the suffix to 'GB'. The
UCL format does recognize 'G' on its own, which uses a base 10 multiplier where
'GB' uses a 2 power multiplier.

Document the difference between valid suffixes when using ctl.conf(5) in the
general syntax form or in UCL format.

Add DSCP support for network QoS to iscsi target.

In order to prioritize iSCSI traffic across a network,
DSCP can be used. In order not to rely on "ipfw setdscp"
or in-network reclassification, this adds the dscp value
directly to the portal group (where TCP sessions are accepted).

The incoming iSCSI session is first handled by ctld for any
CHAP authentication and the socket is then handed off to the
in-kernel iscsi driver without modification of the socket
parameters. Simply setting up the socket in ctld is sufficient
to keep sending outgoing iSCSI related traffic with the
configured DSCP value.

Teach ctld about CTL's physical_port and virtual_port fields.

This allows ctld to work with isp(4) virtual ports, specifying them as
isp0/1, isp0/2, etc. There are still problems on isp(4) layer with
disabling those ports after enabling, but hopefully they can be fixed.

Teach ctld(8) to control non-iSCSI CTL ports.

This change introduces new target option "port", that assigns current target
to specified CTL port. On config application ctld(8) will apply LUN mapping
according to target configuration to specified port and bring the port up.
On shutdown cltd(8) will remove the mapping and put the port down.

This change allows to configure both iSCSI and FibreChannel targets in the
same configuration file in alike way.

CTL LUN mapping rewrite.

Replace iSCSI-specific LUN mapping mechanism with new one, working for any
ports. By default all ports are created without LUN mapping, exposing all
CTL LUNs as before. But, if needed, LUN mapping can be manually set on
per-port basis via ctladm. For its iSCSI ports ctld does it via ioctl(2).
The next step will be to teach ctld to work with FibreChannel ports also.

Respecting additional flexibility of the new mechanism, ctl.conf now allows
alternative syntax for LUN definition. LUNs can now be defined in global
context, and then referenced from targets by unique name, as needed. It
allows same LUN to be exposed several times via multiple targets.

While there, increase limit for LUNs per target in ctld from 256 to 1024.
Some initiators do not support LUNs above 255, but that is not our problem.
