de2763a4b8 ci: Pin clippy to rust 1.78.0 (valued mammal)
Pull request description:
This PR pins clippy check in CI to the rust 1.78 toolchain, which prevents new lints in stable releases from interrupting the usual workflow. Because rust versions are released on a predictable schedule, we can revisit this setting in the future as needed (say 3-6 months).

This fixes the bug with changesets not being monotone. Previously, the
result of applying changesets individually v.s. applying the aggregate
of changesets may result in different `KeychainTxOutIndex` states.
The nature of the changeset allows different keychain types to share the
same descriptor. However, the previous design did not take this into
account. To do this properly, we should keep track of all keychains
currently associated with a given descriptor. However, the API only
allows returning one keychain per spk/txout/outpoint (which is a good
API).
Therefore, we rank keychain variants by `Ord`. Earlier keychain variants
have a higher rank, and the first keychain will be returned.
We only need to loop though entries of `other`. The logic before was
wasteful because we were also looping though all entries of `self` even
if we do not need to modify the `self` entry.
- The KeychainTxOutIndex's internal SpkIterator now uses DescriptorId
instead of K. The DescriptorId -> K translation is made at the
KeychainTxOutIndex level.
- The keychain::Changeset is now a struct, which includes a map for last
revealed indexes, and one for newly added keychains and their
descriptor.
API changes in bdk:
- Wallet::keychains returns a `impl Iterator` instead of `BTreeMap`
- Wallet::load doesn't take descriptors anymore, since they're stored in
the db
- Wallet::new_or_load checks if the loaded descriptor from db is the
same as the provided one
API changes in bdk_chain:
- `ChangeSet` is now a struct, which includes a map for last revealed
indexes, and one for keychains and descriptors.
- `KeychainTxOutIndex::inner` returns a `SpkIterator<(DescriptorId, u32)>`
- `KeychainTxOutIndex::outpoints` returns a `impl Iterator` instead of `&BTreeSet`
- `KeychainTxOutIndex::keychains` returns a `impl Iterator` instead of
`&BTreeMap`
- `KeychainTxOutIndex::txouts` doesn't return a ExactSizeIterator
anymore
- `KeychainTxOutIndex::unbounded_spk_iter` returns an `Option`
- `KeychainTxOutIndex::next_index` returns an `Option`
- `KeychainTxOutIndex::last_revealed_indices` returns a `BTreeMap`
instead of `&BTreeMap`
- `KeychainTxOutIndex::reveal_to_target` returns an `Option`
- `KeychainTxOutIndex::reveal_next_spk` returns an `Option`
- `KeychainTxOutIndex::next_unused_spk` returns an `Option`
- `KeychainTxOutIndex::add_keychain` has been renamed to
`KeychainTxOutIndex::insert_descriptor`, and now it returns a
ChangeSet
We plan to record `Descriptor` additions into persistence. Hence, we
need to add `Descriptor`s to the changeset. This depends on
`miniscript`. Moving this into `txout_index.rs` makes sense as this is
consistent with all the other files. The only reason why this wasn't
this way before, is because the changeset didn't need miniscript.

a577c22b12 fix(persist): add default feature to enable bdk_chain/std (Steve Myers)
Pull request description:
### Description
This PR adds a `default` feature to `bdk_persist` so it can be build on its own. Once #1422 is done we can remove the `default`again.
### Notes to the reviewers
I need to be able to build `bdk_persist` on its own so I can publish it to crates.io.

Pull request description:
fixes#823
<!-- You can erase any parts of this template not applicable to your Pull Request. -->
### Description
It's being used on `Balance`, and throughout the code, an `u64` represents the amount, which relies on the user to infer its sats, not millisats, or any other representation.
It updates the usage of `u64` on `Balance`, and other APIs:
- `TxParams::add_recipient`
- `KeyChainTxOutIndex::sent_and_received`, `KeyChainTxOutIndex::net_value`
- `SpkTxOutIndex::sent_and_received`, `SpkTxOutIndex::net_value`
<!-- Describe the purpose of this PR, what's being adding and/or fixed -->
### Notes to the reviewers
<!-- In this section you can include notes directed to the reviewers, like explaining why some parts
of the PR were done in a specific way -->
It updates some of the APIs to expect the `bitcoin::Amount`, but it does not update internal usage of u64, such as `TxParams` still expects and uses `u64`, please see the PR comments for related discussion.
### Changelog notice
<!-- Notice the release manager should include in the release tag message changelog -->
<!-- See https://keepachangelog.com/en/1.0.0/ for examples -->
- Changed the `keychain::Balance` struct fields to use `Amount` instead of `u64`.
- Changed the `add_recipient` method on `TxBuilder` implementation to expect `bitcoin::Amount`.
- Changed the `sent_and_received`, and `net_value` methods on `KeyChainTxOutIndex` to expect `bitcoin::Amount`.
- Changed the `sent_and_received`, and `net_value` methods on `SpkTxOutIndex` to expect `bitcoin::Amount`.

Pull request description:
<!-- You can erase any parts of this template not applicable to your Pull Request. -->
### Description
Reexports `electrsd` in `TestEnv` to remove the `electrsd` dev depedency out of `bdk_electrum` and `bdk_esplora`.
Credit to @ValuedMammal for the idea.
Since `bitcoind` reexports `anyhow`, this dev dependency was also removed from `bdk_electrum`, `bdk_esplora`, and `bdk_bitcoind_rpc`. `bitcoind`, `bitcoincore_rpc` and `electrum_client` were also reexported for convenience.
### Changelog notice
* Change `bdk_testenv` to re-export internally used crates.

a5fb7fdf50 fix: Cargo clippy lints after rust 1.78 (Daniela Brozzoni)
Pull request description:
<!-- You can erase any parts of this template not applicable to your Pull Request. -->
### Description
Caught when trying to release (#1420), clippy failed randomly although it worked on master, this happened because rust 1.78 had just been release and we use clippy stable. IMHO we should pin the clippy version in CI and bump it manually at each new rust release.

Pull request description:
Fixes#1354
### Description
Built on top of both #1369 and #1373, we simplify the `EsploraExt` API by removing the `update_local_chain` method and having `full_scan` and `sync` update the local chain in the same call. The `full_scan` and `sync` methods now takes in an additional input (`local_tip`) which provides us with the view of the `LocalChain` before the update. These methods now return structs `FullScanUpdate` and `SyncUpdate`.
The examples are updated to use this new API. `TxGraph::missing_heights` and `tx_graph::ChangeSet::missing_heights_from` are no longer needed, therefore they are removed.
Additionally, we used this opportunity to simplify the logic which updates `LocalChain`. We got rid of the `local_chain::Update` struct (which contained the update `CheckPoint` tip and a `bool` which signaled whether we want to introduce blocks below point of agreement). It turns out we can use something like `CheckPoint::insert` so the chain source can craft an update based on the old tip. This way, we can make better use of `merge_chains`' optimization that compares the `Arc` pointers of the local and update chain (before we were crafting the update chain NOT based on top of the previous local chain). With this, we no longer need the `Update::introduce_older_block` field since the logic will naturally break when we reach a matching `Arc` pointer.
### Notes to the reviewers
* Obtaining the `LocalChain`'s update now happens within `EsploraExt::full_scan` and `EsploraExt::sync`. Creating the `LocalChain` update is now split into two methods (`fetch_latest_blocks` and `chain_update`) that are called before and after fetching transactions and anchors.
* We need to duplicate code for `bdk_esplora`. One for blocking and one for async.
### Changelog notice
* Changed `EsploraExt` API so that sync only requires one round of fetching data. The `local_chain_update` method is removed and the `local_tip` parameter is added to the `full_scan` and `sync` methods.
* Removed `TxGraph::missing_heights` and `tx_graph::ChangeSet::missing_heights_from` methods.
* Introduced `CheckPoint::insert` which allows convenient checkpoint-insertion. This is intended for use by chain-sources when crafting an update.
* Refactored `merge_chains` to also return the resultant `CheckPoint` tip.
* Optimized the update `LocalChain` logic - use the update `CheckPoint` as the new `CheckPoint` tip when possible.

`merge_chains` now returns a tuple of the resultant checkpoint AND
changeset. This is arguably a more readable/understandable setup.
To do this, we had to create `CheckPoint::apply_changeset` which is kept
as a private method.

d3a14d411d fix: enable blocking-https-rustls feature on esplora client (thunderbiscuit)
Pull request description:
The [`blocking` feature on the rust-esplora-client library](https://github.com/bitcoindevkit/rust-esplora-client/blame/master/Cargo.toml#L35) changed from ureq to minreq, which does not come with https enabled by default, breaking previously working code that simply enabled the `blocking` feature on the `bdk_esplora` crate.
This change will enable what is currently the "default https" [flag for the minreq library](https://docs.rs/minreq/latest/minreq/#https-or-https-rustls) when using the `blocking` feature on bdk_esplora, reverting that breaking change.
### Notes to the reviewers
Another way we could do this (let me know if this is preferable) is to add a new feature called `blocking-https-rustls`:
```rust
blocking = ["esplora-client/blocking"]
blocking-https-rustls = ["esplora-client/blocking-https-rustls"]
```

Pull request description:
Improvements to the wallet address API, see commit messages for details.
### Notes to the reviewers
The logic of getting addresses is roughly the same as before when using `AddressIndex`, following this mapping:
- `New` -> `reveal_next_address`
- `LastUnused` -> `next_unused_address` (assuming this is what `LastUnused` really means)
- `Peek` -> `peek_address`
Wondering whether it makes sense to expose [`is_used`](358e842dcd/crates/chain/src/keychain/txout_index.rs (L236)) for Wallet as well.

Introduce a new API for getting addresses from the Wallet that
reflects a similiar interface as the underlying indexer
`KeychainTxOutIndex` in preparation for removing `AddressIndex` enum.
Before this change, the only way to get an address was via the methods
`try_get{_internal}_address` which required a `&mut` reference to the
wallet, matching on the desired AddressIndex variant. This is too
restrictive since for example peeking or listing unused addresses
shouldn't change the state of the wallet. Hence we provide separate
methods for each use case which makes for a more efficient API.
e51af49ffa fix(wallet): remove generic from wallet (Rob N)
Pull request description:
### Description
The `PersistenceBackend` uses generics to describe errors returned while applying the change set to the persistence layer. This change removes generics wherever possible and introduces a new public error enum. Removing the generics from `PersistenceBackend` errors is the first step towards #1363
*Update*: I proceeded with removing the generics from `Wallet` by introducing a `Box<dyn PersistenceBackend>` .
### Notes to the reviewers
This one sort of blew up in the number of changes due to the use of generics for most of the `Wallet` error variants. The generics were only used for the persistence errors, so I removed the generics from higher level errors whenever possible. The error variants of `PersistenceBackend` may also be more expressive, but I will level that up for discussion and make any changes required.
### Changelog notice
- Changed `PersistenceBackend` errors to depend on the `anyhow` crate.
- Remove the generic `T` from `Wallet`
