*    libcfs/nidstrings.c does nid parsing/printing.  It's included
     in libptlctl.a for userspace utils too.

*    addr@net - style nids working with > 1 local network

*    router part of portals; ptl_send() uses it to chose the NI, but NALs
     still do am-i-there-yet forwarding.  NAL interface changed to match.

*    reworked nal commands into PtlCtl(ni, cmd, arg) and rewired portals ioctl
     handling.  PtlFailNid, now just another PtlCtl.  NAL interface includes
     ctl handler.

*    commented out all lconf portals config, except setting the NID (pending
     socknal working out its own interfaces)

*    removed all portals config from zeroconf and llmount

*    "lctl network" on its own lists all local NIDs (replaces shownid).
     Most (all?) portals config commands still work from lctl.

*    simplified NAL setup/teardown (no separate nal_cmd and router init)
