     xfstest: add defragmentation stress tests for ext4

     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
