Add support for btrfs in shared/298. Achieve this by introducing 2
new awk scripts that parse relevant btrfs structures and print holes.
Additionally modify the test to create larger - 3gb filesystem in the
case of btrfs. This is needed so that distinct block groups are used
for data and metadata.

If the caller of t_open_tmpfiles wants to shut down the filesystem,
be sure to flush the log when we shut down so that log recovery will
have to process all the unlinked temporary files.
This is apparently needed to force ext4 to flush updated inode
blocks through the journal at all.

A test to perform reads/writes under various cgroups and verify that
I/Os are accounted properly according to cgroup aware writeback.
This is a generic test, but not all commonly used local filesystems
support cgroup aware writeback at the moment (i.e., XFS). Therefore,
this test currently requires ext4 or btrfs for the time being.
The common/cgroup2 file is copied from a separate cgroup related
patch from Shaohua Li that never made it upstream.

XFS had a use-after-free bug when xfs_xattr_put_listent runs out of
listxattr buffer space while trying to store the name
"system.posix_acl_access" and then corrupts memory by not checking
the seen_enough state and then trying to shove
"trusted.SGI_ACL_FILE" into the buffer as well.
In order to tickle the bug in a user visible way we must have
already put a name in the buffer, so we take advantage of the fact
that "security.evm" sorts before "system.posix_acl_access" to make
sure this happens.

Filesystems are not required to try to fill the statx btime field
unless the caller actually sets STATX_BTIME. They're allowed to
volunteer that information "if it's cheap", but XFS doesn't
volunteer and there may be filesystems that support btime but not
cheaply.
Either way, we want to test btime on any filesystem that supports
it, cheaply or otherwise, so set STATX_BTIME when we're trying to
detect support for it.

Currently generic/075 and generic/112 have two extra fsx passes each
that exercise fsx with preallocation, which are only enabled for
XFS.
These tests can also be run with other file systems, given that the
XFS prealloc ioctls are implemented in generic code since the
addition of the fallocate system call. This also means a version of
XFS that does not support preallocation (e.g. because it always
writes out of place) can skip the prealloc tests while still
completing the normal fsx tests just fine.

Test that after a combination of file renames, linking and creating

file, after a power failure we are able to mount the filesystem and
all file names correspond to the correct inodes.
This test is motivated by a bug found in btrfs, which is fixed by
applying the following two patches to the linux kernel:
"[PATCH 1/2] Btrfs: fix fsync after succession of renames of different files"
"[PATCH 2/2] Btrfs: fix fsync after succession of renames and unlink/rmdir"
The test passes on ext4, xfs and patched btrfs, however at least in
a 5.0-rc5 linux kernel, it fails on f2fs.

This test has the number of files/dirs created by xfsrestore hardcoded
in golden output.
When fsstress is added new ops, the number of files/dirs created with
the same random seed changes and this regularly breaks this test,
so when new fsstress ops are added they should be either added to the
dump test blacklist or golden output of this test needs to be ammended
to reflect the change.
The golden output includes only the file count reported by xfsrestore
and test does not even verify that this is the correct file count.
Instead, leave the golden output neutral and explicitly verify that
file count before and after the test are the same.
With this change, the test becomes agnostic to fsstress ops and we
could also stop blacklisting clone/dedup/copy ops if we want.
