write a detailed log of ExecQuiet to a log in /var/tmp during
installation. Good for debugging. Pass -l option to emulab-install or
to update-install.

backtick operation from scripts.

Add LINUX_FSNODE to indicate that the FSNODE is running LINUX.
This is just a partial implementation, intended to support some
changes contributed by Maarten Dewispelaere at intec.ugent.be
Note that these changes do not work with windows enabled, so I added a
check for that.

Add -l argument to boss-install, which turns on detailed ExecQuiet
logging to a separate file in /var/tmp. This is reflected in
emulab-install which is called from from boss-install.

uClibc doesn't support bcopy() or bzero() by default, and for some
reason the current configuration doesn't have the appropriate option
enabled like it should.  I will fix it, but to avoid future issues
should the configuration become borked again we should use memcpy()
and memset() instead.

When a node with the secure boot dongle is freed, it goes into PXEWAIT in
the context of the secure MFS. Previously we remained in "secure mode"
(i.e., did not terminate with a TPMSIGNOFF) while a node was in this state.
If the next use of the node, just booted from the OS that was already on
the disk, then we never signed off properly.

Now we sign off before entering PXEWAIT. I thought that this would be the
easiest alternative to fixing the problem..HaHaHa..not! Because now we have
to restart the secure boot path (i.e., reboot) if the result of coming out
of PXEWAIT is a request to reload the disk (i.e., if we are continuing the
secure disk load path).

Ideally this would have required only modifications to the state machines
for SECUREBOOT/LOAD, but as you can see by the presence of stated.in in the
modified files, this was not the case. The change required some additional
"finesse" to get it working. See the comments in stated.in and bootinfo_mysql.c
if you really care.

bootwhat will now return a FLAGS=%d value corresponding to the flags
field in the boot_what struct.

NOTE: THIS REQUIRED A TMCD VERSION BUMP. We are now at version 35.
The issue was backward compatibility with existing CD/dongle boot images
which are overly strict in their parsing of the returned bootwhat values.

Added a new boot_what flag (the whole point of this) to signify if the
entity being returned is part of the "secure boot" path. This is used
by the gPXE dongle to determine whether it needs to do a trusted boot
path "sign-off" for the MFS it downloads. We used to use the name of
the MFS as our heuristic for this.

bootinfo uses the new tbdb.os_info osfeature "ontrustedboot" to determine
whether to set the flag.

Modified bug fix from Mark Carson <mecarson@gmail.com>.

This is in the node type check where we look at what is currently in the
partition they are imaging, and base the set of valid node type on that.
However, if they specify a partition that doesn't currently have an image,
we would previously effectively tell them that the image will not run on
the node type that it is currently running on!

Now we just say "there is no current image in that partition."

As if things weren't hairy enough for the pxe_boot_path, we need a per-node
default value. This should not be confused with the next_pxe_boot_path or
pxe_boot_path fields in the nodes table, which is a per-node value but only
for the lifetime of the current experiment.

We need this new field specifically so that we can switch some, but not all,
of the d710s over to the TPM-aware pxeboot.

For the record, the select order for setting the filename field in
dhcpd.conf is:

 1. nodes.next_pxe_boot_path for node
 2. nodes.pxe_boot_path for node
 3. "pxe_boot_path" node_attribute for node
 4. "pxe_boot_path" node_type_attribute for node type
 5. don't set (i.e., use the dhcpd.conf global default).

node. This happens when building a tunnel on a virtual node using a
0.2 rspec; the old manifest put the URN of the virtual node in, while
the V2 manifest puts in the physical node. Since resolving a virtual
node returns nothing useful even now, I figure this is safe.
