No longer relevant because Boost 1.46 is no longer supported and std::unordered_map is used instead of boost::unordered_map in CCoinsMap.
SaltedSipHasher is a generic hasher that can be used with most things we would hash in an unordered container.
Move the hashers that we use for hash tables to a common place. Moved hashers: - SaltedTxidHasher - SaltedOutpointHasher - FilterHeaderHasher - SignatureCacheHasher - BlockHasher
