The "status" command reports the amount of scrub necessary to
ensure to scrub all the synced blocks.
* Reduced the RAM memory usage, expecially with big files.
For each block, it now uses 17 bytes, instead of 28 bytes
(for 32 bit) and 36 bytes (for 64 bit).
* The -p, --percentage option supports the new the arguments:
"bad", "sync" and "full" to define the kind of scrub to do.
* Drastically reduced the memory usage. For each block, it now
uses 17 bytes of memory, instead of the previous 28 bytes
(for 32 bit) or 36 bytes (for 64 bit).
This could result is a memory saving of up the 50%.
* Extends the -h, --pre-hash option to also verify moved and
copied files into the array before running a 'sync'.
* Update 'best' RAID functions for recent Atom CPUs.
