[svn-r12661] Description:
Add 'loookup3' checksum routine and switch to using it for metadata
checksums - it's just as "strong" as the CRC32 and about 40% faster in general
(with some compiler optimizations, it's nearly as fast as the fletcher-32
algorithm).
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
