This change adds offline unit testing for `wallet2::process_parsed_blocks()`, the main driver of the chain-processing logic in `wallet2`. The transactions are constructed using `cryptonote::construct_tx_and_get_tx_key`, which makes them realistic to pruned transactions that appear in the wild. The `fake_pruned_blockchain` maintains lists of `cryptonote::block_complete_entry` and `tools::wallet2::parsed_block` structs for each block, with easy miner transaction adding, automatic assigning of unique output indices for outputs in the block, and correct blockID hashing. The blockchain can also start at an offset, but if it starts at 0, then it uses the real genesis block for that network type. Part of upstreaming Carrot.

wallet2::process_parsed_blocks(), the main driver of the chain-processing logic inwallet2. The transactions are constructed usingcryptonote::construct_tx_and_get_tx_key, which makes them realistic to pruned transactions that appear in the wild.

The blockchain can also start at an offset, but if it starts at 0, then it uses the real genesis block for that network type.The provided unit test creates one of each transaction type a-h, adds it to the fake blockchain, then calls
wallet2::process_parsed_blocks()on the block data. After each update, it checks that the balance increases according to the amount in the relevant transaction output.Part of upstreaming Carrot.
