The check script requires that it be run as root, so adding
individualized checks for this in each teat is not needed.

This makes it clear when we are using "mount ; umount" versus "mount
-o remount" for most file systems. The reason for this distinction is
(a) tests may want to test the difference between what happens on the
remount versus the munt paths, (b) with tmpfs, "mount ; umount" will
cause the contents of all of the files to disappear which makes many
tests sad, and (c) some mount options may not be changed using "mount
-o remount".
Currently _scratch_mount performs "_scratch_mount ; _scratch_umount"
so mechnically rename this function to _scratch_cycle_mount. This was
done mechnically using the script fragment:
git grep "_scratch_remount" | \
awk -F: '{print $1}' | sort -u | \
xargs sed -i 's/_scratch_remount/_scratch_cycle_mount/g'

Test that doing a direct IO write against a file range that contains one
prealloc extent and one compressed extent works correctly.
From the linux kernel 4.0 onwards, this either triggered an assertion
failure (leading to a BUG_ON) when CONFIG_BTRFS_ASSERT=y or resulted
in an arithmetic underflow of an inode's space reservation for write
operations.
That issue is fixed by the following linux kernel patch:
"Btrfs: fix extent accounting for partial direct IO writes"

Move the cp --reflink tests from btrfs/ to generic/ since xfs now
supports that ioctl.

Currently we're checking file system consistency on TEST_DEV after every
successful test run even though the TEST_DEV might not even be used in
that test.
Fix it by introducing _require_test to for the test ti indicate that
it's about to use TEST_DEV.
Also add _require_test to the new script so that this requirement is a
default.

Number of helpers for checking xfs_io functionality is slowly
growing. But it's as easy to simply use _require_xfs_io_command()
directly and just specify the command we want to check. It will also
avoid the need to create helper every time we need to check a new
command in xfs_io.
Remove all the helpers and use _require_xfs_io_command() in the
tests.

Tests file clone functionality of btrfs ("reflinks"):
- Reflink a file
- Reflink the reflinked file
- Modify the original file
- Modify the reflinked file
[sandeen: add helpers, make several mostly-cosmetic
changes to the original testcase]
