The test case will check SHARED flag returned by fiemap ioctl on
reflinked files before and after sync.
Normally SHARED flag won't change just due to a normal sync
operation.
But btrfs doesn't handle SHARED flag well, and this time it won't
check any delayed extent tree(reverse extent searching tree)
modification, but only metadata already committed to disk.
So btrfs will not return correct SHARED flag on reflinked files if
there is no sync to commit all metadata.
This testcase will just check it.

Some tests were merged with high, non-conflicting test numbers
(700+). Renumber them down to contiguous numbers now that all the
other tests have been added, as it's easier to do it this way rather
than having to rebase and have to fix all the conflicts early
renumbering will cause.

Test creating a symlink, fsync its parent directory, power fail and mount
again the filesystem. After these steps the symlink should exist and its
content must match what we specified when we created it (must not be
empty or point to something else).
This is motivated by an issue in btrfs where after the log replay happens
we get empty symlinks, which not only does not make much sense from a
user's point of view, it's also not valid to have empty links in linux
(wgich is explicitly forbidden by the symlink(2) system call).
The issue in btrfs is fixed by the following patch for the linux kernel:
"Btrfs: fix empty symlink after creating symlink and fsync parent dir"
Tested against ext3, ext4, xfs, f2fs, reiserfs and nilfs2.

Fairly trivial test to use the dm-thin infrastructure.
Right now it exhausts space in queue-on-error mode,
adds more space, does a bit more IO, then unmounts &
checks the fs.
Not sure if that's valid to test, but it works here and
demonstrates the common/dmthin helpers.
