Builds release but not test Requires implementation of GetBlockHashesAndIndexOfTransactionHashes in ChainStore, to enable REST to look up block hashes and tx indexes from tx hashes Memory use of AddressState will explode with this change - requires either spilling to disk and/or using CompactUTxOIdentifier internally and then a restituted GetUTXOHashes to look up as before.

Reverts UTXOIdentifier to being (tx_hash, output_index), enabling bootstrap from snapshot.
Work In Progress!
Description
Reverts UTXOIdentifier - and hence storage key in UTXOState - to being tx hash based, removing memory optimisation through UTXORegistry in TxUnpacker (which has been removed).
This also means the REST queries need to look up TX hashes to get block hashes and tx indexes within the block - there is a new GetBlockHashesAndIndexOfTransactionHashes query to do this, but it needs implementing. I'm not sure if ChainStore has the indexes to do this.

Checklist
Impact / Side effects
The memory use of AddressState will explode with this change - requires either spilling to disk and/or using CompactUTxOIdentifier internally and then a restituted GetUTXOHashes to look up as before.
