policy: Refactor PkOrF into an enum 
For whatever reason we were using a struct as an enum, so we might as
well fix it in this PR since we are already breaking the API quite
badly.

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [Unreleased]
- added `OldestFirstCoinSelection` impl to `CoinSelectionAlgorithm`
- New MSRV set to `1.56`
- Unpinned tokio to `1`
- Add traits to reuse `Blockchain`s across multiple wallets (`BlockchainFactory` and `StatelessBlockchain`).
- Upgrade to rust-bitcoin `0.28`
- If using the `sqlite-db` feature all cached wallet data is deleted due to a possible UTXO inconsistency, a wallet.sync will recreate it
- Update `PkOrF` in the policy module to become an enum
## [v0.18.0] - [v0.17.0]
- Add `sqlite-bundled` feature for deployments that need a bundled version of sqlite, ie. for mobile platforms.
- Added `Wallet::get_signers()`, `Wallet::descriptor_checksum()` and `Wallet::get_address_validators()`, exposed the `AsDerived` trait.
- Deprecate `database::Database::flush()`, the function is only needed for the sled database on mobile, instead for mobile use the sqlite database.
- Add `keychain: KeychainKind` to `wallet::AddressInfo`.
- Improve key generation traits
- Rename `WalletExport` to `FullyNodedExport`, deprecate the former.
- Bump `miniscript` dependency version to `^6.1`.
## [v0.17.0] - [v0.16.1]
- Removed default verification from `wallet::sync`. sync-time verification is added in `script_sync` and is activated by `verify` feature flag.
- `verify` flag removed from `TransactionDetails`.
- Add `get_internal_address` to allow you to get internal addresses just as you get external addresses.
- added `ensure_addresses_cached` to `Wallet` to let offline wallets load and cache addresses in their database
- Add `is_spent` field to `LocalUtxo`; when we notice that a utxo has been spent we set `is_spent` field to true instead of deleting it from the db.
### Sync API change
To decouple the `Wallet` from the `Blockchain` we've made major changes:
- Removed `Blockchain` from Wallet.
- Removed `Wallet::broadcast` (just use `Blockchain::broadcast`)
- Deprecated `Wallet::new_offline` (all wallets are offline now)
- Changed `Wallet::sync` to take a `Blockchain`.
- Stop making a request for the block height when calling `Wallet:new`.
- Added `SyncOptions` to capture extra (future) arguments to `Wallet::sync`.
- Removed `max_addresses` sync parameter which determined how many addresses to cache before syncing since this can just be done with `ensure_addresses_cached`.
## [v0.16.1] - [v0.16.0]
- Pin tokio dependency version to ~1.14 to prevent errors due to their new MSRV 1.49.0
## [v0.16.0] - [v0.15.0]
- Disable `reqwest` default features.
- Added `reqwest-default-tls` feature: Use this to restore the TLS defaults of reqwest if you don't want to add a dependency to it in your own manifest.
- Use dust_value from rust-bitcoin
- Fixed generating WIF in the correct network format.
## [v0.15.0] - [v0.14.0]
- Overhauled sync logic for electrum and esplora.
- Unify ureq and reqwest esplora backends to have the same configuration parameters. This means reqwest now has a timeout parameter and ureq has a concurrency parameter.
- Fixed esplora fee estimation.
## [v0.14.0] - [v0.13.0]
- BIP39 implementation dependency, in `keys::bip39` changed from tiny-bip39 to rust-bip39.
- Add new method on the `TxBuilder` to embed data in the transaction via `OP_RETURN`. To allow that a fix to check the dust only on spendable output has been introduced.
- Update the `Database` trait to store the last sync timestamp and block height
- Rename `ConfirmationTime` to `BlockTime`
## [v0.13.0] - [v0.12.0]
- Exposed `get_tx()` method from `Database` to `Wallet`.
## [v0.12.0] - [v0.11.0]
- Activate `miniscript/use-serde` feature to allow consumers of the library to access it via the re-exported `miniscript` crate.
- Add support for proxies in `EsploraBlockchain`
- Added `SqliteDatabase` that implements `Database` backed by a sqlite database using `rusqlite` crate.
## [v0.11.0] - [v0.10.0]
- Added `flush` method to the `Database` trait to explicitly flush to disk latest changes on the db.
## [v0.10.0] - [v0.9.0]
- Added `RpcBlockchain` in the `AnyBlockchain` struct to allow using Rpc backend where `AnyBlockchain` is used (eg `bdk-cli`)
- Removed hard dependency on `tokio`.
### Wallet
- Removed and replaced `set_single_recipient` with more general `drain_to` and replaced `maintain_single_recipient` with `allow_shrinking`.
### Blockchain
- Removed `stop_gap` from `Blockchain` trait and added it to only `ElectrumBlockchain` and `EsploraBlockchain` structs.
- Added a `ureq` backend for use when not using feature `async-interface` or target WASM. `ureq` is a blocking HTTP client.
## [v0.9.0] - [v0.8.0]
### Wallet
- Added Bitcoin core RPC added as blockchain backend
- Added a `verify` feature that can be enable to verify the unconfirmed txs we download against the consensus rules
## [v0.8.0] - [v0.7.0]
### Wallet
- Added an option that must be explicitly enabled to allow signing using non-`SIGHASH_ALL` sighashes (#350)
#### Changed
`get_address` now returns an `AddressInfo` struct that includes the index and derefs to `Address`.
## [v0.7.0] - [v0.6.0]
### Policy
#### Changed
Removed `fill_satisfaction` method in favor of enum parameter in `extract_policy` method
#### Added
Timelocks are considered (optionally) in building the `satisfaction` field
### Wallet
- Changed `Wallet::{sign, finalize_psbt}` now take a `&mut psbt` rather than consuming it.
- Require and validate `non_witness_utxo` for SegWit signatures by default, can be adjusted with `SignOptions`
- Replace the opt-in builder option `force_non_witness_utxo` with the opposite `only_witness_utxo`. From now on we will provide the `non_witness_utxo`, unless explicitly asked not to.
## [v0.6.0] - [v0.5.1]
### Misc
#### Changed
- New minimum supported rust version is 1.46.0
- Changed `AnyBlockchainConfig` to use serde tagged representation.
### Descriptor
#### Added
- Added ability to analyze a `PSBT` to check which and how many signatures are already available
### Wallet
#### Changed
- `get_new_address()` refactored to `get_address(AddressIndex::New)` to support different `get_address()` index selection strategies
#### Added
- Added `get_address(AddressIndex::LastUnused)` which returns the last derived address if it has not been used or if used in a received transaction returns a new address
- Added `get_address(AddressIndex::Peek(u32))` which returns a derived address for a specified descriptor index but does not change the current index
- Added `get_address(AddressIndex::Reset(u32))` which returns a derived address for a specified descriptor index and resets current index to the given value
- Added `get_psbt_input` to create the corresponding psbt input for a local utxo.
#### Fixed
- Fixed `coin_select` calculation for UTXOs where `value < fee` that caused over-/underflow errors.
## [v0.5.1] - [v0.5.0]
### Misc

- Pin `hyper` to `=0.14.4` to make it compile on Rust 1.45
## [v0.5.0] - [v0.4.0]
### Misc
#### Changed
- Updated `electrum-client` to version `0.7`
### Wallet

#### Added
- Added support for the `signet` network (issue #62)
