[PATCH 0/4 v3] XFS TESTS: Fix 252 failure

This patch corrects a 252 test failure when run on ext4.  This failure
occures because ext4 and xfs do not handle splitting extents in the same way, 
and do not create the same fiemap outout.

To correct this, this patch set will make test 252 an xfs only test, and a new 
test 255 will be added.  The new test is similar to 252, but uses a weaker fiemap filter
that only shows the location of the hole, and not the extent type.  An
md5 check sum has also been added to the tests to help ensure the contents are
correct.

Also, another patch was submitted that modifies the same code in 242.out.
Assuming that patch will go through, this set was modified to be applied on 
top of Christoph's "[PATCH] xfstests: update test 042 golden output" (06/20/2011). 

I noticed there are some other patches that are trying to add a test 255, so we 
may need another version of this set depending on which ones go in first.
