Remove $FreeBSD$: two-line nroff pattern

Remove /^\.\\"\n\.\\"\s*\$FreeBSD\$$\n/

Retire obsolete iscsi_initiator(4)

The new iSCSI initiator iscsi(4) was introduced with FreeBSD 10.0, and
the old intiator was marked obsolete shortly thereafter (in commit
d32789d95cfbf, MFC'd to stable/10 in ba54910169c4). Remove it now.

Add "iscsictl -e". Among other things, it makes it possible to perform
discovery without attaching to the targets ("iscsictl -Ad ... -e off"),
and then attach to selected ones ("iscsictl -Mi ... -e on").

Add more text to explain --libxo flag.

Add -w flag to iscsictl(8) utility, to make it wait for successfull
session establishment. Scripting is kind of hard without it.

without removing it and adding back.

Grammar fix.

Make it clear that there are two ways to add a session using iscsictl(8),
and some options require configuration file.

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.
