The latter causes on/off/cycle operations to return a generic error
(though the operations do work!)

We could plumb this through to a config var, but let's leave it a hack
for now and see if we can find the root cause instead.

This commit is intended to makes the license status of Emulab and
ProtoGENI source files more clear.  It replaces license symbols like
"EMULAB-COPYRIGHT" and "GENIPUBLIC-COPYRIGHT" with {{{ }}}-delimited
blocks that contain actual license statements.

This change was driven by the fact that today, most people acquire and
track Emulab and ProtoGENI sources via git.

Before the Emulab source code was kept in git, the Flux Research Group
at the University of Utah would roll distributions by making tar
files.  As part of that process, the Flux Group would replace the
license symbols in the source files with actual license statements.

When the Flux Group moved to git, people outside of the group started
to see the source files with the "unexpanded" symbols.  This meant
that people acquired source files without actual license statements in
them.  All the relevant files had Utah *copyright* statements in them,
but without the expanded *license* statements, the licensing status of
the source files was unclear.

This commit is intended to clear up that confusion.

Most Utah-copyrighted files in the Emulab source tree are distributed
under the terms of the Affero GNU General Public License, version 3
(AGPLv3).

Most Utah-copyrighted files related to ProtoGENI are distributed under
the terms of the GENI Public License, which is a BSD-like open-source
license.

Some Utah-copyrighted files in the Emulab source tree are distributed
under the terms of the GNU Lesser General Public License, version 2.1
(LGPL).

Renamed the library to power_apc.pm since it has nothing to
do with snmpit, and it fooled me, and I don't want to be fooled
again, cause you know what means.

Openflow OIDs can be used in snmpit_hp now, so the functions can act correctly. Command line options configuration is changed to use only one vlanname for each OF command. The order of OF support checking and finding VLan is changed so that stack module will find vlan first, then check OF support. Thus there will not be an error msg for OF unsupported even if the vlan is not on the switch.

about "mib-2" and some others.  This is defined in SNMPv2-SMI which wasn't
in the list of MIB files and is needed by SNMPv2-MIB.  But, it probably
shouldn't need to be explicitly included, since there is an IMPORT of the
symbols in question at the beginning of SNMPv2-MIB.  But I added it to
the SNMP::addMibFiles() arguments anyway.

This came about because I was messing with PowerNet-MIB.txt to support the
7960 power controllers (we have an 8 year old version of that file).

pointing out this issue.

Waiting to hear back from DETER about their power controllers however,
so this may change again...

The default for the perl SNMP library has apparently changed.

once. This is particularly helpful when rebooting nodes connected to
the RPCs, as you now longer have to wait through the RPCs 'rebooting'
junk for each node.

power_rpc27.pm and snmpit_apc.pm received some minor changes to
support passing multiple outlets to one function call.
