[PATCH] fstests: add orangefs (pvfs2) support

[Martin Brandenburg <martin@omnibond.com>]

The filesystem was renamed OrangeFS from PVFS2 recently.  The mount -t
type remains pvfs2, so I have used that name throughout despite the
kernel module being named orangefs.

We've been maintaining this as a patch for quite some time.

The easiest way to use is to setup a single server installation with
multiple filesystems orangefs and scratch, put the following in
/etc/xfsqa.config, and run ./check -pvfs2 -g quick.

TEST_DIR=/mnt
TEST_DEV=tcp://server1vm:3334/orangefs
SCRATCH_MNT=/scratch
SCRATCH_DEV=tcp://server1vm:3334/scratch
