reassigning inodes in restored files without needing to sync
again the file.
This happens only if the file has the same name, size and timestamp
This happens only if the file has the same path, size and timestamp
at nanosecond precision.
* Added a hash seed to make harder intentional collision attacks.
* When insering files for the first time, sort them by their physical
address to improve read performance.
* Optimized the cache use for the all the RAID computations.

They are a little faster than the previous unroll by 2.
