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]

Test for an issue in btrfs send where it sent clone operations to user
space with a range (offset + length) that was not aligned with the block
size. This caused the btrfs receive command to send such clone operations
to the ioctl clone API, which would return -EINVAL errors to btrfs receive,
causing the receive command to abort immediately.

We have no tests for testing qgroups, so we have no way of knowing
if our changes are breaking qgroups at all. Get the ball rolling
with some basic functionality tests, these just make sure we can
enable quotas and do rescan and get sane values back, as well as
make sure the limiting stuff works properly.

We had a regression where we were not copying csums properly when balancing a
prealloc extent. Unfortunately the way this showed up the most was with the
csum simply missing, which doesn't result in an error to userspace. So I've
copied what generic/310 does and check dmesg for csum errors when the test
starts and then compare that count to the csum errors after the test finishes to
see if there was a problem. This approach caught the error without my fix, and
then passed fine with my fix in place but with the previous errors still in
dmesg. Thanks,

This test performs btrfs device replace tests with all possible profiles
(single/dup/mixed/raid0/raid1/raid10), one round with the '-r' option
to 'btrfs replace start' and one round without this option. The
cancelation is tested only once and with the dup/single profile for
metadata/data.
This test takes 181 seconds on my SSD equiped test box and 237s on
spinning disks. Almost all the time is spent when the filesystem is
populated with test data. The replace operation itself takes less than
a second for all the tests, except for the test that is marked as
'thorough' which will run for about 8 seconds on my test box.
The amount of tests done depends on the number of devices in the
SCRATCH_DEV_POOL. For full test coverage, at least 5 devices should
be available (e.g. 5 partitions). With less than 2 entries in
SCRATCH_DEV_POOL, the test is not executed.
The source and target devices for the replace operation are arbitrarily
chosen out of SCRATCH_DEV_POOl. Since the target device mustn't be
smaller than the source device, the requirement for this test is that
all devices have _exactly_ the same size. If this is not the case, the
test terminates with _notrun.
To check the filesystems after replacing a device, a scrub run is
performed, a btrfsck run, and finally the filesystem is remounted.
This commit depends on my other commit:
"xfstest: don't remove the two first devices from SCRATCH_DEV_POOL"

These are tests that are shared between multiple filesystems (moved
to shared), and udf/btrfs/ext4 specific tests, moved to appropriate
directories.
I created the "shared" directory to indicate tests that are not
truly generic, but also not filesystem specific. They might rely on
a feature that is only implmented in a few filesystems and so can't
be truly generic.
