[Bug 439868] Re: UEC images could be smaller

[Scott Moser]

hopefully final resize script. I know this is a bad place for revision
control, so hopefully this will be the last thing put here.  Then, we'll
put this somewhere in bzr.

Newly attached version:
 - works to increase or decrease size of filesystem
 - catches errors and gives error messages (rather than set -e)
 - only uses zcat when necessary (for copies of our 10G uncompressed images, using straight copy is ~25% faster on clock, uses less sys resources too)
 - changes usage from:
  resize-uec-image <old> <new> <size>
  to
  resize-uec-image <old> <size> [new]
  ie, works in place if new is not given (this will not work on a compressed file, obviously).
