* 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
* 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

* 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
* 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
