[PATCH 01/10] xfstests: add --largefs check option

[Dave Chinner <david@fromorbit.com>]

From: Dave Chinner <dchinner@redhat.com>

Make it easier to check large filesystems quickly by adding a
--large-fs option to check to turn on shortcuts for large scratch
device filesystem testing.

Also, reject invalid command line options with a usage message.
