Fix periph listing when IOCTL buffer border hits result for wanted bus.

MFC r264876:

Grammar fix.

MFC r262525:

There is no need to prevent iscsictl from adding iSER session when there
is no iSER support in ctld and/or kernel; should the user make that mistake,
the output from "iscsictl -L" is enough to determine what the problem is.

Hoist all the mergeinfo up to the root in preparation for enforcing merges
to the root only. All MFC's were rerecorded to the root.

Going forward, if an MFC includes mergeinfo, it will need to be made to
the root and committed from the root. Merges with --ignore-ancestry
or diff | patch can go anywhere.

The mergeinfo in HEAD is in a bad state from years of neglect and manual
tampering and this was branched into 10.x. This confuses the coalescing
code and prevents it from doing its job.

MFC r257379:

Rename '-h' option to '-p', and use "portal" instead of "host" or "address",
in order to be consistent with iSCSI terminology. Besides, calling the
option '-h' was just wrong.

This changes usage for newly added iscsictl(8), and two newly added
subcommands to ctladm(8). This breaks POLA between CURRENT and 10,
but since 10.0 has not been released yet, it's still ok to do.

MFC r257380:

Bump .Dd after r257379.
