In _require_defrag defragmentation command path is fixed. That will
cause that this test case is skipped in some distributions.

Perform various regression tests for ext4defrag subsystem
301'th Test1: Defragment file while other task does direct AIO
302'th Test2: Perform defragmentation on file under buffered AIO
while third task does direct AIO to donor file
303'th Test3: Two defrag tasks use common donor file.
304'th Test4: Stress defragmentation. Several threads perform
fragmentation at random position use inplace=1 will
allocate and free blocks inside defrag event improve
load pressure.
This tests are considered dangerous because 302'th and 303'th are known
to trigger OOPS on recent kernels see:https://gist.github.com/dmonakhov/4770294

Btrfs progs has a defragment tool, so we can test 218 on btrfs now.

blkid knows to identify the ext4dev FSTYP of a partition that was
formatted with mkfs.ext4dev.
quota tools and various util-linux utils are also aware of ext4dev,
so ext4dev shares the same capabilities as ext4.

While most tests use /bin/sh, they are dependent on /bin/sh being a
bash shell. Convert all the tests to execute via /bin/bash as it is
much, much simpler than trying to debug and remove all the bashisms
throughout the test code.

This test creates some files, runs defrag on them,
and compares the before/after fragmentation as well
as file md5sums and timestamps.
The test currently expects to find e4defrag in
/usr/bin
It should be relatively easy to add more interestingly
fragmented files to the tests, as well as to test
that memory-mapped files aren't touched, etc -
but this gives us a framework.
V2: remount before checking file contents, and create
common.defrag.
