We were assuming that if static_widearea_config returned 0, it had
configured the physical $iface that findcnet was passed successfully.
But, static_widearea_config also returns 0 if the widearea config info
was present BUT if the given physical $iface did not match the widearea
config info.

So, catch that case, and all is well.

Also, fix a minor syntax bug; and add some debugging.

Part of our hack strategy to detect and correct transient NFS errors
is to fsync after every file write and check for errors. However, some
devices don't support fsync. So, for example, if you were trying to
imagezip to /dev/null (to benchmark or check the resulting image size)
fsync would always fail and we would keep retrying the write forever.

There is already a "-N" option to avoid such checks and retries, but
Mike can never remember that!

The script still blows up on a glob of an empty directory.

What source to read the info from and which enternal array to fill.

Controlled by new sitevars.

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

Check the version of bash we are about to run. It must be version 4
to support associative arrays.

The compareunits function does not return a result now. Rest of the changes are in formatting output files.

Compare ether addrs in lower case, compare disk serial numbers in upper case.
Don't change the loop termination var while in the loop.
Unset exit on error when doing read operation. Returns a non-zero status.
Don't create a hwinfo file if not requested by the function arguments

Save the runtime listing of tmcc hwinfo. Do more checking on file add/removes. Don't do a recursive chmod -R.

compare with the full inventory that was found not just what should be in the tbdb. Needed since disks that don't have a serial will be skipped by the compare function.
