Sometimes it is not easy to know number of expected extents in advance.
In that case it is reasonable to provide sane MIN and MAX values.
Also helper will check that number of extents before defragmentaion
is not greather than after.

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.

Btrfs has always failed shared/218 because of the way we allocate extents on
disk. The last part of 218 writes contiguously holey from the start of the file
forward, which for btrfs means we get 16 extents but they are physically
contigous. filefrag -v shows all 16 extents, but prints out that there is 1
extent, because they are physically contiguous. This isn't quite right and
makes the test fail. So instead of using filefrag use xfs_io -c fiemap which
will print the whole map and then get the count from there. With this patch
btrfs now passes the test, I also verified that ext4 and xfs still pass this
test. Thanks,

Some tests 'cd <somedir>' and then direct output to $RESULT_DIR,
which fails if the current working directory is not $here.
Regardless, if an external results directory is to be used it needs
to have a full path specified and the use of $here as the base of
the results files is completely incorrect.
Hence change all the $here/$seqres* references to simply be
$seqres*, and instead encode the full path to the results in
$RESULT_DIR.

Introduce a top level common directory and move all the common.*
files into it. Because there is now a directory named common, the
prefix can be dropped from all the files. Convert all the tests to
use this new directory for including common files.
for f in common.*; do \
git mv `echo -n "$f " ; echo $f | sed -e 's;n\.;n/;'` \
done
