mkfs.xfs does not do a very good job of input validation. This test
is designed to exercise the input validation and test good/bad
combinations of options being set. It will not pass on an old
mkfs.xfs binary - it is designed to be the test case for an input
validation cleanup (merged in spring/summer 2016).

XFS used to retry forever on non-critical errors, and unmount could
hang in such case. Commit e6b3bb78962e ("xfs: add "fail at unmount"
error handling configuration") introduced an error configuration
option in sysfs(fail_at_unmount) and made this behavior
configurable.
Now test this "fail_at_unmount" behavior to make sure XFS doesn't
retry forever on error at unmount time, if configured so. Also
introduced new helpers to require/set/get sysfs attributes.

XFS has a bug where directory readahead completions can occur after
unmount. This can lead to a crash or panic because metadata read
verification attempts to access core XFS data structures (e.g., the
log) after they have been freed and certain pointers have been
reset.
Add a test that triggers directory readahead, delays the readahead
I/O and immediately unmounts the filesystem. This test is part of
the dangerous group as it will cause kernels affected by the bug to
crash.

Make sure that we can handle multiple bmbt records mapping to a
single rmapbt record. This can happen if you fallocate more than
2^21 contiguous blocks to a file.
(Also add some helpers that can create huge devices with some
dm-zero and dm-snapshot fakery.)

XFS had a bug in the multi-block buffer logging code that caused a
NULL lv panic at log push time due to invalid regions being set in
the buffer log format bitmap. This was demonstrated by modifying a
multi-block directory buffer in a manner that only logs regions
beyond the first FSB-sized mapping of the buffer.
To recreate these conditions, this test fragments free space and
populates several directories with enough entries to require
discontiguous multi-block buffers. To recreate the problem, we
remove entries from the tail end of the directory and fsync to flush
the log.
Note that this test causes a panic on kernels affected by the bug.
As such, it is included in the 'dangerous' group. The bug is
resolved by kernel commit a3916e528b91 ("xfs: fix broken multi-fsb
buffer logging").

xfs/006 has no requirements that are specific to XFS, so make it generic
and other filesystems could get some coverage too.
Along with the movement, I also added a test that removes all created
dirs, as that's how the original bug was found.

When default quota is set, all different quota types inherits the
same default value, include group quota. So if a user quota limit
larger than the default user quota value, it will still be limited
by the group default quota value.
