Here is the second posting of the FSID change support for user space. For 
background information refer to the the initial posting [0]. The major changes
in this version are: 
 - Modified the sequence of operations when changing the fsid. Now it's split
 among 2 transactions with the first one setting a flag (similarly to what 
 the old fsid change code does) and the second transaction applying the new 
 FSID and incompat flag

 - Expanded the test coverage with several crafted images which simulate 
 failure scenarios that could occur while fsid change is in progress. 

 - Also added the last 2 clean up patches which can be merged independently of
 the fsid changes.
