Assign $OVERLAY_MOUNT_OPTIONS to UNIONMOUNT_MNTOPTIONS and require
that unionmount supports UNIONMOUNT_MNTOPTIONS if OVERLAY_MOUNT_OPTIONS
was provided.
For example, when the mount option metacopy=on is set in
$OVERLAY_MOUNT_OPTIONS, it enables the --meta test option and affects
the test verifications after copy up.

Add support for running unionmount-testsuite from xfstests.
This requires that unionmount-testsuite is installed under src dir or
that UNIONMOUNT_TESTSUITE variable points to the location of the
testsuite. It also requires a recent version of unionmount-testsuite
that supports setting basedir path via UNIONMOUNT_* environment variables.
Add tests for three basic configurations:
1. overlay with upper/lower on same fs
2. overlay with upper/lower not on same fs without xino
3. overlay with upper/lower not on same fs with xino
The samefs test uses scratch partition for lower/upper layers.
The non samefs tests use the scratch partition for upper layer and the
test partition for lower layer.

The tests were checking that nfs_export feature was successfully enabled
by greping for nfs_export=on option in /proc/mounts.
This check was incorrect if the module default was nfs_export enabled
and caused test to not run with the message:
cannot enable nfs_export feature on nested overlay
Use a helper that checks this condition correctly.

xfs_info version 5.0.0 started using findmnt to find the
filesystem to query. This change resulted in a regression
of _scratch_remount when testing overlay over xfs.
For example, test overlay/035, started to report:
[not run] overlay/035 -- upper fs needs to support d_type
Internally, '_overlay_scratch_mount -o remount' calls
'_supports_filetype $OVL_BASE_SCRATCH_MNT -o remount'
and with the following example mounts:
/dev/vdf /vdf xfs rw,relatime,attr2,inode64,noquota 0 0
/vdf /vdf/ovl-mnt overlay rw,lowerdir=/vdf/lower,upperdir=/vdf/upper...
'_supports_filetype /vdf' returns false and reports:
"/vdf/ovl-mnt: Not on a mounted XFS filesystem".
Regardless of the change in xfs_info, which I proposed a fix
for, there is no reason to test d_type support on remount.
Therefore, fix the regression by skipping unneeded overlayfs
mount logic on remount.

fsck.overlay should return correct exit code to show the file system
status after fsck, instead of return 0 means consistency and !0 means
inconsistency or something bad happened.
Fix the following three exit code after running fsck.overlay:
- Return FSCK_OK if the input file system is consistent,
- Return FSCK_NONDESTRUCT if the file system inconsistent errors
corrected,
- Return FSCK_UNCORRECTED if the file system still have inconsistent
errors.
This patch also add a helper function to run fsck.overlay and check
the return value is expected or not.
[amir] rename helper to _overlay_fsck_expect, split define of FSCK_*
to a seprate path.

_repair_scratch_fs did not do the right thing for overlay.
Implement and call _repair_overlay_scratch_fs to repair
overlay filesystem and then fall through to repair base filesystem.
The only tests currentrly calling _repair_scratch_fs on a
./check -overlay run are generic/330 generic/332 in case the
base fs supports reflink. The rest of the tests calling
_repair_scratch_fs require that $SCRATCH_DEV is a block device.

Commit ea7ad43 ("fstests: implement require of multiple overlayfs
features") changed the message when tests are not run due to missing
overlayfs feature.
Restore the check for existing module param before trying to mount
which restores the old message format, e.g.:
[not run] feature 'metacopy' not supported by overlay

Tests that use _overlay_scratch_mount_dirs instead of _scratch_mount
should use _require_scratch_nocheck instead of _require_scratch
because these tests are either mounting with multiple lower dirs or
mounting with non-default lower/upper/work dir, so
_check_overlay_scratch_fs won't handle these cases correctly. So we
introduce _overlay_check_scratch_dirs helper and should call this
helper with the correct dir arguments for these non-default cases.
This patch modify these tests to optionally call
_overlay_check_scratch_dirs at the end of the test or after
_scratch_umount to mount base filesystem only and run the checker.

Hook filesystem check helper to _check_test_fs and _check_scratch_fs
for checking consistency of underlying dirs of overlay filesystem.
These helpers works only if fsck.overlay exists.
This patch introduce OVERLAY_FSCK_OPTIONS use for check overlayfs like
OVERLAY_MOUNT_OPTIONS, and also introduce a mount point check helper in
common/rc to detect a dir is a mount point or not.

Previously _scratch_mount didn't check the mount status and most
tests continue to run even if the mount failed (unless test checks
for the mount status explicitly). This would result in running tests
on the underlying filesystem (usually rootfs) and implicit test
failures, and such failures can be annoying and are usually hard to
debug.
Now _fail test by default if _scratch_mount failed and introduce
_try_scratch_mount for tests that need to check mount results
themselves.

Add some helper functions to require that we can reload a given
module, and add a helper to actually do that. Refactor the existing
users to use the generics.
We need to hoist completely the behaviors of the old btrfs module
helper because we need to confirm before starting the test that we
actually can remove the module.
