[PATCH 0/4] fstests: rudimentary overlayfs testing support, take two

Adding basic overlayfs support to fstests, it doesn't test anything
overlayfs specific, but runs existing tests on top of overlayfs. It's
following the path from Eric's patchset and Zab's review back in Mar.

A new fstype "overlay" is added, and TEST_DEV/SCRATCH_DEV are required
to be fs paths, and overlayfs is mounted at TEST_DIR/SCRATCH_MNT, so
tests can be run there.

I tested with the following config, the backing fs of TEST_DEV and
SCRATCH_DEV are both XFS

TEST_DEV=/mnt/ovl/test
TEST_DIR=/mnt/testarea/test
SCRATCH_DEV=/mnt/ovl/scratch
SCRATCH_MNT=/mnt/testarea/scratch

./check -overlay -g auto

Some tests failed:
generic/003 atime not updated (should _notrun on overlayfs?)
generic/062 failed to create whiteout device, fixed in patch 3
overlayfs lacks of selinux support
generic/079 overlay dir inode has no ioctl method, fixed in patch 4
generic/192 atime not updated (should _notrun on overlayfs?)
generic/193 suid not cleard on write, will fix overlayfs
generic/31[49] overlayfs not inherit default acl, will fix overlayfs

Patch 1 is from Eric, which introduces mount/umount helper functions to
mount/umount test and scratch devices. I did minor updates.

Patch 2 introduces the overlay support.

Patch 3 fixes generic/062 failure, but it still fails due to lack of
selinux support on overlayfs.

Patch 4 fixes generic/079 failure.

Thanks,
Eryu
