e8df3d2d91 Consolidate `fee_amount` and `amount_needed` (Cesar Alvarez Vallero)
Pull request description:
### Description
Before this commit `fee_amount` and `amount_needed` were passed as independent
parameters. From the perspective of coin selection algorithms, they are always
used jointly for the same purpose, to create a coin selection with a total
effective value greater than it's summed values.
This commit removes the abstraction that the use of the two parameter
introduced by consolidating both into a single parameter, `target_amount`, who
carries their values added up.
Resolves: #641
### Notes to the reviewers
I just updated old tests and didn't create new ones because almost all changes
are renames and "logic changes" (like the addition of the selection fee) are
tested in the modified tests.

### Description
This PR mainly fixes two bugs:
1. TXIN_BASE_WEIGHT wrongly included the `script_len` (Fixes#160)
2. We wouldn't take into account the segwit header in the fee calculation, which could have resulted in a transaction with a lower feerate than the requested one
3. In tests we used to push 108 bytes on the witness as a fake signature, but we should have pushed 106 instead
I also add a test to reproduce the conditions of #660, to check if it's solved. Turns out it's been solved already in #630, but if you're curious about what the bug was, here it is: https://github.com/bitcoindevkit/bdk/issues/660#issuecomment-1196436776

We would previously always try to sign with the taproot internal
key, and try to sign all the script leaves hashes.
Instead, add the `sign_with_tap_internal_key` and `TapLeaveOptions`
parameters, to be able to specify if we should sign with the internal
key, and exactly which leaves we should sign.
Fixes#616
Issue #660 has been fixed by 32ae95f463,
when we moved the change calculation inside the coin selection.
This commit just adds a test to make sure that the problem is fixed.
We would previously push 108 bytes on a P2WPKH witness
to simulate signature + pubkey. This was wrong: we should push
106 bytes instead.
The max satisfaction size for a P2WPKH is 112 WU:
elements in witness (1 byte, 1WU) + OP_PUSH (1 byte, 1WU) +
pk (33 bytes, 33 WU) + OP_PUSH (1 byte, 1WU) + signature and sighash
(72 bytes, 72 WU) + scriptsig len (1 byte, 4WU)
We should push on the witness pk + signature and sighash. This is 105
WU. Since we push just once instead of twice, we add 1WU for the OP_PUSH
we are omitting.
...selecting coins
We take into account the larger segwit tx header for every
transaction, not just the segwit ones. The reason for this is that
we prefer to overestimate the fees for the transaction than
underestimating them - the former might create txs with a slightly
higher feerate than the requested one, while the latter might
create txs with a slightly lower one - or worse, invalid (<1 sat/vbyte)!
We would before calculate the TXIN_BASE_WEIGHT as prev_txid (32 bytes) +
prev_vout (4 bytes) + sequence (4 bytes) + script_sig_len (1 bytes), but
that's wrong: the script_sig_len shouldn't be included, as miniscript
already includes it in the `max_satisfaction_size` calculation.
Fixes#160
We would previously calculate the fee amount in two steps:
1. Add the weight of the empty transaction
2. Add the weight of each output
That's unnecessary: you can just use the weight of the transaction
*after* the output addition. This is clearer, but also avoids a
rare bug: if there are many outputs, adding them would cause the
"number of outputs" transaction parameter lenght to increase, and we
wouldn't notice it.
This might still happen when adding the drain output - this
commit also adds a comment as a reminder.
235011feef Add assertions in the FeeRate constructor (Alekos Filini)
Pull request description:
### Description
Disallow negative, NaN, infinite or subnormal fee rate values.
### Notes to the reviewers
This commit is technically an API break because it makes the `FeeRate::from_sat_per_vb` function non-const. I think it's worth it compared to the risk of having completely nonsensical fee rates (that can break the coin selection in interesting ways).
EDIT: it's also a breaking change because our code can now panic in scenarios where it didn't before. Again, I think it's worth it.

32ae95f463 Move change calculus to coin_select (Cesar Alvarez Vallero)
Pull request description:
### Description
The former way to compute and create change was inside `create_tx`, just after
performing coin selection.
It blocked the opportunity to have an "ensemble" algorithm to decide between
multiple coin selection algorithms based on a metric, like Waste.
Now, change is not created inside `coin_select` but the change amount and the
possibility to create change is decided inside the `coin_select` method. In
this way, change is associated with the coin selection algorithm that generated
it, and a method to decide between them can be implemented.
Fixes#147.

5c940c33cb Fix wallet sync not finding coins of addresses which are not cached (志宇)
Pull request description:
Fixes#521Fixes#451
^ However, only for electrum-based `Blockchain` implementations. For RPC and Compact Block Filters, syncing works differently, and so are the bugs - I have created a separate ticket for this (#677).
### Description
Previously, electrum-based blockchain implementations only synced for `scriptPubKey`s that are already cached in `Database`.
This PR introduces a feedback mechanism, that uses `stop_gap` and the difference between "current index" and "last active index" to determine whether we need to cache more `scriptPubKeys`.
The `WalletSync::wallet_setup` trait now may return an `Error::MissingCachedScripts` error which contains the number of extra `scriptPubKey`s to cache, in order to satisfy `stop_gap` for the next call.
`Wallet::sync` now calls `WalletSync` in a loop, caching in-between subsequent calls (if needed).
#### Notes to reviewers
1. The caveat to this solution is that it is not the most efficient. Every call to `WalletSync::wallet_setup` starts polling the Electrum-based server for `scriptPubKey`s starting from index 0.
However, I feel like this solution is the least "destructive" to the API of `Blockchain`. Also, once the `bdk_core` sync logic is integration, we can select specific ranges of `scriptPubKey`s to sync.
2. Also note that this PR only fixes the issue for electrum-based `Blockchain` implementations (currently `blockchain::electrum` and `blockchain::esplora` only).
3. Another thing to note is that, although `Database` assumes 1-2 keychains, the current `WalletSync` "feedback" only returns one number (which is interpreted as the larger "missing count" of the two keychains). This is done for simplicity, and because we are planning to only have one keychain per database in the future.

2c02a44586 Test: No address reuse for single descriptor (志宇)
Pull request description:
### Description
Just a simple new test.
This test is to ensure there are no regressions when we later change
internal logic of `Wallet`. A single descriptor wallet should always get
a new address with `AddressIndex::New` even if we alternate grabbing
internal/external keychains.
I thought of adding this during work on #647

6db5b4a094 Introduce `get_checksum_bytes` method and improvements (志宇)
Pull request description:
### Description
`get_checksum_bytes()` returns a descriptor checksum as `[u8; 8]` instead of `String`, potentially improving performance and memory usage.
In addition to this, since descriptors only use characters that fit within a UTF-8 8-bit code unit ([US-ASCII](https://www.charset.org/charsets/us-ascii)), there is no need to use the `char` type (which is 4 bytes). This can also potentially bring in some performance and memory-usage benefits.
### Notes to the reviewers
This is useful because we will be using descriptor checksums for indexing operations in the near future (multi-descriptor wallets #486 ).

Pull request description:
### Description
Fixes#649
It is critical to ensure `Wallet::get_address` with `AddressIndex::new` always returns a new and unused address.
This bug seems to be Electrum-specific. The fix is to check address index updates to ensure that newly suggested indexes are not smaller than indexes already in database.

This bug seems to be Electrum-specific. The fix is to check the
proposed changes against the current state of the database. Ensure
newly suggested indexes are not smaller than indexes already in
database.
Changes:
* Check index updates before they are applied to database during
Electrum Blockchain sync (Thank you @rajarshimaitra for providing
an elegant solution).
Tests added:
* bdk_blockchain_tests!::test_sync_address_index_should_not_decrement
* bdk_blockchain_tests!::test_sync_address_index_should_increment
These tests ensure there will be no unexpected address reuse when
grabbing a new address via `Wallet::get_address` with `AddressIndex::New`.
Other changes:
* Tweak `rpc.rs` so that clippy is happy.
45db468c9b Deprecate `AddressValidator` (志宇)
Pull request description:
### Description
`AddressValidator` should be deprecated as noted by @afilini [on Discord](https://discord.com/channels/753336465005608961/753367451319926827/994899488957272064):
> address validators are supposed to be used for a slightly different thing, which is when you ask the hardware wallet to independently generate the address for a derivation index and then you compare what you see on your computer/phone with what the hardware wallet is displaying
> in the case of change addresses i agree that it's not as important (because as you said the device can just refuse to sign) but for consistency we implemented it for both external and internal addresses
> more broadly, they can be thought of as a way to get a callback every time an address is generated, which may also be useful for other things (for example when i was working on a green-compatible client written in bdk i used that feature to ping the server every time a new address was generated, because that's required in their protocol)
> that said, i think currently pretty much nobody uses them and i am myself moving away from the concept that "everything needs to happen inside bdk": currently my mindset is targeted more towards reducing complexity by breaking down individual parts and wrapping them or making them "extensible" in some way
> that is to say: if you want to verify addresses in your hardware wallet you don't necessarily need bdk to do it for you (actually, you would still have to implement the callback manually), you can just call bdk to get a new addr and then ping the device yourself. and this would allow us to reduce complexity and delete some code
> actually, here's an idea: unless somebody here is opposed to this, i can make a pr to deprecate address validators in the next (0.20) release. if after that again nobody complains we can completely remove them and point users towards different strategies to achieve the same goal

This test is to ensure there are no regressions when we later change
internal logic of `Wallet`. A single descriptor wallet should always get
a new address with `AddressIndex::New` even if we alternate grabbing
internal/external keychains.

c2e4ba8cbd add remove_partial_sigs to SignOptions (KaFai Choi)
Pull request description:
<!-- You can erase any parts of this template not applicable to your Pull Request. -->
### Description
This PR is to add 2 keys(`try_finalize` and `remove_partial_sigs`) in `SignOptions`. See this issue for detail https://github.com/bitcoindevkit/bdk/issues/612
### Notes to the reviewers
~I found the negative naming of these 2 new keys `do_not_finalize` and `do_not_remove_partial_sigs` are a bit confusing(like most negative named paremeter/variable). Should we actually change it back to positive naming(`do_finalize` and `do_remove_partial_sigs`)?~

populate_test_db would previously give back a transaction with N + 1
confirmations when you asked for N.
This commit also fixes test_spend_coinbase, which would improperly
ask for a transaction with 0 confirmations instead of 1.
