This patch adds additional punch hole tests to 252
that were used to test ext4 punch hole. The _test_generic_punch
routine has been modified to accept two new flags:

-k To keep the test file between tests.
   This will test the handling of existing holes

-d To not sync the file between tests.
   This will test the handling of delayed extents

Four new corner cases have also been added to the routine:
14. data -> hole @ EOF
15. data -> hole @ 0
16. data -> cache cold ->hole
17. data -> hole in single block file

Looks good, I'll put it in.
