hammer - Add memory use limit option for dedup runs
* Add '-m memlimit' (default 1G) to limit memory use during a dedup run.
If the limit is reached hammer will reduce the range of CRCs in the scan
and will perform multiple passes as needed to dedup the entire filesystem.
* VerboseOpt (-v) will be verbose about crc-range truncation and multiple
passes.
