This adds a regression test for the following kernel patch:
b4678df184b3 ("errseq: Always report a writeback error once")
This is motivated by some rather odd behavior done by the PostgreSQL
project. The main database writers will offload the fsync calls to a
separate process, which can open files after a writeback error has
already occurred.
This used to work with older kernels that reported the error to only
one fd, but with the errseq_t changes we lost the ability to see
errors that occurred before the open. The above patch restores that
behavior.

The tests _require_test_lsattr, but don't actually use lsattr. They
use chattr +i/-i, so require the appropriate command.
_require_test_lsattr checks the FS_IOC_GETFLAGS ioctl on a directory
and that is not supported in overlayfs. _require_chattr checks the
ioctl on a file, which is supported in overlayfs, so this change
makes the tests run and pass on overlayfs.

The 3 tests that _require_xfs_io_command "flink", actually require
O_TMPFILE support and flink command, but the former is far unlikely
to be missing. The test btrfs/058 doesn't even use the flink
command.
When running these tests on a filesystem that does not support
O_TMPFILE (e.g. overlayfs) the result is not very infomative:
generic/004 1s ... [not run] xfs_io flink failed (old kernel/wrong fs?)
Decouple the requirements for "flink" command and "-T" command line
flag and require the former explicitly in tests that use it.
As a result the report is now more informative:
generic/004 1s ... [not run] O_TMPFILE is not supported

There are a bunch of tests that are run by the auto group that are

Multiple origin references to the same lower file from upper files
that are not hardlinks will falsely return the same st_ino/st_dev
for two different overlay files and will cause 'diff' to falsely
report that content of files is the same when it is not.
This test checks that overlayfs detects and fails lookup of a
multiply referenced origin.
The check for multiply referenced origin was a by-product of kernel
commit 31747eda41ef ("ovl: hash directory inodes for fsnotify")

Test description says: "This is the same test as generic/156 except
that we also check the inode reflink flag.", only since commit
f1c3fee ("xfs: remove NOCOW_FL testing from test") it is almost
exactly the same test as generic/156.
almost - because since xfs/132 diverged from generic/156 the change
911efb0 ("reflink: change to relative margins") is only applied to
the original test.
Anyway, there doesn't seem to be a reason to keep this duplicated
test anymore, so remove it.

Everyone who starts using fstests runs "check" without parameters,
and then has problems with it running dangerous tests. most people
just want fstests to act as a regression test suite, not a fuzzer or
exercise known crash conditions. Hence make the default behaviour to
be "run the auto group" rather than "run every test".
To enable people to run all tests easily (if they really want to)
add a special group keyword named "all". This wildcard will trigger
selecting all the tests in fstests as per the original "check
without parameters" behaviour.

The install-sh file is much more efficient than the libtool version
(50% faster wall clock time; much more than that when running in a

real need for the libtool version, so bring back the original
install-sh script.

The blocktrash fuzz tests for xfs will try to mount and write to the
filesystem after corrupting it. However, the mount may not necessarily
succeed, in which case we must not write junk to the root filesystem.
Use the new _try_scratch_mount to guard against that.

Since we've rewriting the xfs_scrub Unicode name scanner to use libicu
to detect potential spoof names, change our check for unicode-enabled
name scanning xfs_scrub to look for libicu instead of libunistring,
adjust the golden output to reflect the new library's detection
capabilities and make sure we get all the scrub output by invoking with
-v.
Note that this requires xfsprogs 4.16 or newer; since xfs_scrub is (for
now) an experimental program, we don't care about breaking backwards

Kanda Motohiro reported that expanding a tiny xattr into a large
xattr fails on XFS because we remove the tiny xattr from a shortform
fork and then try to re-add it after converting the fork to extents
format having not removed the ATTR_REPLACE flag. This fails because
the attr is no longer present, causing a fs shutdown.

POSIX requires that record locks are preserved across an execve(2).
But currently the locks are released if process is multithreaded at
the time that execve is called.
As Jeff Layton wrote in his patch:
"
In that case, we'll end up unsharing the files_struct but the locks
will still have their fl_owner set to the address of the old one.
Eventually, when the other threads die and the last reference to the
old files_struct is put, any POSIX locks get torn down since it
looks like a close occurred on them.
The result is that all of your open files will be intact with none
of the locks you held before execve.
"
Add a new regression test for this particular case.
