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

7. change(db): Use smaller keys for height and transaction indexes (#3874)
* Increment the database format version

* Update IntoDisk and FromDisk docs

* Rename fixed_byte_len to fixed_disk_byte_len

* Add functions that truncate and extend serialized bytes

* Store heights in 3 bytes on disk

* Update database raw data snapshots for 3-byte heights

* Log an error if we ever get close to the maximum disk height

* Store transaction indexes in 2 bytes on disk

* Update database raw data snapshots for 2-byte transaction indexes

* Make doc comment phrasing consistent

* Replace IntoDiskFixed with fixed constants

* Replace u32 byte length literal with a constant calculation

* Fix off-by-one error in MAX_ON_DISK_HEIGHT

* Add proptest seeds for the MAX_ON_DISK_HEIGHT off-by-one error

* Remove redundant module from a Height type

3. refactor(db): add disk serialization types for transactions (#3741)
* refactor(db): simplify block height serialization

* refactor(db): make height serialization length generic

* refactor(db): create a TransactionIndex type

This changes the names of some snapshot types,
but doesn't change any data.

* refactor(db): create transparent OutputIndex and OutputLocation types

This keeps the same serialization, to avoid changing the database version.

* doc(rfc/db): make transparent database type names consistent

* doc(rfc/db): fix a bug in the Utxo.is_coinbase derivation

* fix(db): use the correct serialized size for OutputLocation

2. refactor(db): split the raw disk serialzation format into modules (#3717)
* doc(db): fix some comments

* refactor(db): split disk serialization types into their own module

* refactor(db): split the disk format into modules

* doc(db/test): explain the RON serialization format
