2. feat(db): Add address balance indexes to the finalized state (#3963)
* Add an empty balance_by_transparent_addr column family

* Add an AddressBalanceLocation type for balance_by_transparent_addr

* Add serialization for balance_by_transparent_addr types

* Add round-trip tests for the new serialized types

* Add missing round-trip and serialized equality tests

* Add a network field to DiskWriteBatch

* Refactor confusing all_utxos_spent_by_block argument

It was actually just the UTXOs from the state spent by the block,
excluding the UTXOs created and spent within the block.

But now we need it to contain all the spent outputs,
including the ones created by the block.

* Read and update address balances in the finalized state

* Update raw data snapshots for transparent address balances

* Add test-only deserialization for transparent addresses

* Add high-level snapshot test code for address balances

* Add high-level snapshots for address balances

* Increment the state version after NU5 testnet 2 rollback

1. feat(db): Store transactions in a separate database index, to improve query speed (#3934)
* Implement disk serialization for block headers and transactions

* Re-order column family initialization to match the design

* Add new empty transaction column families

* Split writing block header and transaction data

* Re-order column families for consistency

* Update write snapshots for transaction split

* Use split block and transaction data when reading

* Update snapshots to include genesis transaction hash location

* Filter all prefix iterators to make sure they return the correct values

* Test that the new transaction indexes are consistent

* Add some cleanup TODOs

* Increment the database format to version 15

* Remove unused fisk format impls for Block

* Add a missing prefix extractor for transaction locations

* Make the database generic over the thread mode

* Replace prefix iteration with iteration from a key, and a filter

Prefix iteration caused database hangs.

* Manually iterate through transaction locations to re-create blocks

Also:
- re-write disk read API to avoid iterator hangs
- move disk read API to ReadDisk
- re-write impl rocksdb::AsColumnFamilyRef to a where clause, for consistency

* Update the database version so it's larger than the NU5 testnet 2 version

0. change(db): Use Ribbon filters for database index lookups (#4040)

6. add(test): add more tests for height and transaction location serialization (#3879)
* Add round-trip test for OutputLocation disk serialization

* Make the transaction snapshot tests more accurate

Previously, we were showing the genesis transaction hash at height 0, index 0.

But its hash is actually not stored by location in the database,
because the genesis transaction is skipped due to a consensus rule.

* Update the transaction snapshot data

* Add history tree snapshot tests

At the current test heights, the history trees are all empty.

* Add the history tree snapshot data

* Update comments

* Simplify snapshot test code

* Make some serde::Serialize impls test-only, so we can hex-encode them

This should also speed up release compilation a bit.

* Add snapshot test code for UTXOs

* Add snapshot data for UTXOs

3. fix(state): prevent watch channel deadlocks in the state (#3870)
* Revert "Drop the Chain watch channel lock before accessing the finalized state"

This reverts commit 8870944d1323fc31e2d009b9938623de6fcbe50f.

* Add a WatchReceiver wrapper that always clones the borrowed watch data

This avoids deadlocks, by holding the read lock for as short a time as possible.

* Drop the shared Arc<Chain>s as quickly as possible

This reduces memory usage.

* Make read::block more flexible, by accepting any AsRef<Chain>

* Make the block method docs consistent

* Avoid livelocks by explicitly dropping the borrow after the clone

Add an OrderedUtxo type for transparent spend validation (#2502)
* Add an OrderedUtxo type for validation of spends within a block

This change allows us to check that transparent spends use outputs from
earlier in their block. (But we don't actually do that check yet.)

We need to keep the order of UTXOs when we're contextually verifying
each new block that is added to a chain. But the block order is
irrelevant for UTXOs stored in the state.

Use the block verifier and non-finalized state in the cached state tests (#2463)
* Use the block verifier and non-finalized state in the cached state tests

This substantially increases test coverage.

Previously, the cached state tests were configured with
`checkpoint_sync = true`, which only uses the checkpoint
verifier and the finalized state.

* Log the source of blocks in commit_finalized_direct

This lets us check that we're actually testing the non-finalized state
and block verifier in the cached state tests.

It also improves diagnostics for state errors.

* Fail cached state tests if they're using incorrect heights or configs

This makes sure that the cached state tests actually test the transition
from checkpoint to block verification, and the non-finalized state.

Henry de Valence 342eb166ff state: track UTXO provenance
This commit changes the state system and database format to track the
provenance of UTXOs, in addition to the outputs themselves.
Specifically, it tracks the following additional metadata:

- the height at which the UTXO was created;
- whether or not the UTXO was created from a coinbase transaction or
  not.

This metadata will allow us to:

- check the coinbase maturity consensus rule;
- check the coinbase inputs => no transparent outputs rule;
- implement lookup of transactions by utxo (using the height to find the
  block and then scanning the block) for a future RPC mechanism.

Closes #1342

zebra-state: replace sled with rocksdb (#1325)
## Motivation

Prior to this PR we've been using `sled` as our database for storing persistent chain data on the disk between boots. We picked sled over rocksdb to minimize our c++ dependencies despite it being a less mature codebase. The theory was if it worked well enough we'd prefer to have a pure rust codebase, but if we ever ran into problems we knew we could easily swap it out with rocksdb.

Well, we ran into problems. Sled's memory usage was particularly high, and it seemed to be leaking memory. On top of all that, the performance for writes was pretty poor, causing us to become bottle-necked on sled instead of the network.

## Solution

This PR replaces `sled` with `rocksdb`. We've seen a 10x improvement in memory usage out of the box, no more leaking, and much better write performance. With this change writing chain data to disk is no longer a limiting factor in how quickly we can sync the chain.

  - [x] Unit Tests and Property Tests
