This's a functional test case for mount --move operation, it verifies
below semantics:
---------------------------------------------------------------------------
| MOVE MOUNT OPERATION |
|**************************************************************************
|source(A)->| shared | private | slave | unbindable |
| dest(B) | | | | |
| | | | | | |
| v | | | | |
|**************************************************************************
| shared | shared | shared | shared & slave | invalid |
| | | | | |
|non-shared| shared | private | slave | unbindable |
***************************************************************************
NOTE: moving a mount residing under a shared mount is invalid.
This case uses fsstress to produce a little random load, to make
sure basic operations won't break the the moved mountpoints.

Test that if we clone part of an extent from a file to itself at a
different offset, fsync it, rewrite (COW) part of the extent from the
former offset, fsync it again, power fail and then mount the filesystem,
we are able to read the whole file and it has the correct data.
This is motivated by a bug found in btrfs which is fixed by a kernel patch
that has the following subject:
"Btrfs: fix missing data checksums after replaying a log tree"

Dave Chinner reports[1] that an appending AIO DIO write to the second
block of a zero-length file and an fallocate request to the first block
of the same file can race to set isize, with the user-visible end result
that the file size is set incorrectly to one block long. Write a small
test to reproduce the results.
