95c4a39244 Make iser(4) buildable again by adjusting it for the recent changes
in ICL interface.

 - the ordering of parameters to icl_conn_task_setup is different, so that
   the "cookie" is last.
 - the icl_conn_connected() method is gone, replaced by much simpler mechanism.
   I'd rather keep the ICL interface as small as possible.
 - I don't really like the s/offload/driver/g.  The "tcp" is not a driver;
   "iser" is not really a driver either.  I'd prefer to leave it as it is.
 - the check for ic_session_type_discovery() in iser_conn_handoff() is gone,
   as handoff cannot happen for discovery sessions.
 - ic_session_login_phase() and ic_session_type_discovery() are gone.  If you
   had your handoff method called - you're no longer in either of those.
 - the way maxtags is passed is different; now it's simply ic->ic_maxtags.
   It's cleaner, and the old way would cause weird things to happen if
   fail_on_disconnection=1 and the user changed the maxtags sysctl before
   reconnecting (basically the CAM idea of maxtags would be different from
   iSER one).
 - icl_hba_misc() is gone; declare support for PIM_UNMAPPED by setting
   ic->ic_unmapped flag.
 - the way we find the "iser" ICL module is rewritten - we have a flag
   for icl_register() that says if the module is iSER-capable or not.
 - icl_conn_release() is gone; iser_conn_release() is called from
   iser_conn_free() (no functional change in this case) and at the beginning
   of icl_conn_connect(), to handle reconnection.

4814a0a4ce Bring in the Mellanox implementation of iSER (iSCSI over RDMA) initiator,
written by Sagi Grimberg <sagig at mellanox.com> and Max Gurtovoy
<maxg at mellanox.com>.

This code comes from https://github.com/sagigrimberg/iser-freebsd, branch
iser-rebase-11-current-r291993.  It's not connected to the build just yet;
it still needs some tweaks to adapt to my changes to iSCSI infrastructure.

Big thanks to Mellanox for their support for FreeBSD!
