Split PrefHashStore into PrefHashStore and PrefHashStoreTransaction.
All a PrefHashStore can now do is hand off PrefHashStoreTransactions.
PrefHashStoreTransactions are used to determine the scope of a series of updates to the PrefHashStore and do one-time computation at the end when required.
This change is aimed in particular at updating the hash_of_hashes only once at the end of a series of updates to multiple hashes rather than recomputing it every time a hash is stored in that serie.
