[PATCH V2 0/5] Fix Btrfs tests to work on non-4k block sized fs instances

This patchset fixes Btrfs tests to work on variable block size. This
is based off the RFC patch sent during March of this year
(https://www.marc.info/?l=linux-btrfs&m=142736088310300&w=2).

Currently, some of the tests are written with the assumption that 4k
is the block size of the filesystem instance. On architectures
(e.g. ppc64) with a larger page size (and hence larger block size),
these tests fail because the block bondaries assumed by the the tests
are no longer true.

To fix the issue, This patchset adds two new filter functions:
1. _filter_xfs_io_blocks_modified
2. _filter_od

Changes from V1:
1. Remove faulty patches which incorrectly compared a file's md5sum
output before and after performing file operations instead of
echoing it to stdout.
