to be inserted into the main template before generating the file config
file. Handy when there are relatively simple local customizations that
are independent of the main template.

change is rolled into the main template and subboss template.

to go from PXEBOOTING (pxewakeup) to actually booting, but we do not
know that for a really long time cause we send a BOOTING event from
bootinfo right after PXEBOOTING, since that was the only place to hook
it in. Well Mike discovered the "on commit" support in dhcpd, and so
that is what we are going to use now. Note that uboot nodes have been
using on commit, now all nodes will when BOOTINFO_EVENTS=0.

Mike's reportboot program is now a daemon, renamed to report_daemon.
The original reportboot program is a little script that writes the
arguments from dhcpd to a unix socket to be picked up by the daemon,
which does the original work of mapping the IP/Mac to a node id and
sending an event. The code has also been modified to run on a subboss
using the same node mapping given to to dhcpd, reconstituted as DBM
file by subboss_dhcpd_makeconf.

The reason for using a daemon this way is so that we do not hang up
dhcpd in case we cannot get to the event system. The unix domain
socket will give us some amount of buffering, but I suspect that any
event problem will eat that space up quickly, and I will be back to
revisit this (probably want reportboot to not block on its write
to the socket).

pxeboot changed to not send PXEBOOTING or BOOTING when
BOOTINFO_EVENTS=0.

Since the Moonshot cluster will soon have x86 nodes and those nodes do
call bootinfo (unlike the ARM nodes), make sure that bootinfo does not
send PXEBOOTING/BOOTING events (since dhcpd already has) by starting it
with the new -E option.

Formalize by adding a BOOTINFO_EVENTS defs var that defaults to 1.
This ensures that a nobootinfo version of the dhcpd.conf template is
installed and that bootinfo is invoked with the -E option.
Only defs-cloudlab-utah should set it to zero.

This is analogous to what we do in bootinfo to ensure we don't fire off
excessive PXEBOOTING/BOOTING events. The DB file is in the new
/usr/testbed/db directory.

A concession to performance. Previously, PXEBOOTING was reported on
the PXE DHCP request and BOOTING on the following OS-originated request.
This is conceptually ideal, as that is what those states were intended
to mean, but it causes two synchronous "reportboot" command executions
from dhcpd for every node boot. Worse, the time gap between the second,
OS-originated DHCP call and the first explicit state reported by the
node itself (e.g., TBSETUP or RELOADSETUP) is generally small enough
that the node reported state often arrived at stated before the BOOTING
state from dhcpd. This can cause excess node reboots or other undesirable
behaviors from stated.

So now we only invoke "reportboot" on the first PXE-originated call and
tell reportboot to send both PXEBOOTING and BOOTING events at that time.
This does not eliminate the race condition above, but makes it unlikely
as there is the whole kernel boot process (10s of seconds) between the
dhcpd state reports and the first node state report.

Keeping them up to date throughout the node lifecycle is not a lot of fun...

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.

- Add support for new tmcd dhcpdconf command to watchdog
- Fix dhcpd.conf template so that ddns-update-style is set to none
- Pull some utility functions from boss's libtestbed.pm into the client
  libtestbed.pm for use by subboss_dhcpd_makeconf and daemon_wrapper.
- Add stuff to simplify getting control interface IP address.

Add the bootinfo_server attribute for specifying the bootinfo server the
node should use during the boot process.  If not specified the node will
default to trying the tftp server and dhcp server, in that order.

PXE vendor option 128 is used to communicate this to the NBP. Options
128-254 are available for NBP-specific use according to the PXE spec, so
we're safe using it.
