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.

I forgot to define $seqres in btrfs/026-029. As a result, a file named
.full was created in the current working directory. Fix it.

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]
