The mapping of old-school adX devices to new-school adaX names needs to
be fixed. I put an enumeration of the first 8 possibilities in there,
but it should be fixed in a more general way. Ideally by using the kernel's
message about "adaN: previously known as adM".

Also change diskcheck to use this option when trying to force WCE on.

"na" in them. Change the string to NotApp(case senstive).

running in MFS mode on the d710 nodes which have been set up for
TPM booting.

Major issues:
The MFS image for TPM booting is 32bit while other Linux MFS images
are 64bit.
The TPM kernel only supports 4Gb of memory, does not support
multi-processors.

checkutils: Make sure the dd to be run is bit-with compatiable with
the image.
cpucheck: Check and handle missing cpu flags "physical id",
"cpu cores", "siblings". Check and handle different Mhz format.
diskcheck: Differnet blocks/sectors format. Rewrite getwspeed and
getspeed funtions to handle dd and tdd compatibility and/or missing
binaries. Give better error messages for timing speed failures.

Strengthen logic/better code in write-cache reporting. Look for new formatting given by newer smartctl

* remove check for gather arg, use TESTINFO from tmcc hwinfo
  instead. Only call tmcc once. Let non-MFS boot collect data.
* tmcc hwinfo not return a TESTINFO line. Handle the LOGDIR, COLLECT
  and CHECK indicators
* Do to variable scoping make sure everything runs in the shell.
  Do not 'exit' from called programs. Source called programs instead
  of starting new shells.
* Nothing wrong with the which() function I put in since the
  MFS/busybox installation does not have one, but if we have a real
  which(1) program use it.
* output format changes and programming space changes
* remove check for gather arg, use TESTINFO from tmcc hwinfo
  instead. Only call tmcc once. Let non-MFS boot collect data.

* call sub-programs by sourcing not by starting new shell.
* oops mfsmode is not set until initialize is run. also set -e -u to
  catch this type of thing.

Checknode tests once again run in standard images and can collect
data.

* All tests can now be "sourced" from gatherinv to insure everything
  runs in a single shell.
* All tests can also be called standalone.
* MFS mode and non-MFS mode honor the CHECK and COLLECT flags.
* Create, if necessary, a new project save directory.
* This will be needed once every-time checknodes is run in a new project.
  path is /proj/{pid}/nodecheck.
* If script can't run quit with a 'return 0' so the rest of the checks
  can continue.

Change filename gatherinv -> checknode

* Can't run in MFS mode if not in the emulab-ops pid

if we have a small device, such as a USB drive, don't pretend that we know what r/w speed, serial or type.

Also, some cleanup.

Merge rc.config changes into the real script.
Reduce rc.nodecheck varients to a single shell script and get rid of rc subdir.
Add copyrights.
Add GNUmakefile install target (but not used yet).
Replace some hardwired paths with vars from paths.sh.
