Upgrade miniscript/bitcoin dependency
Upgrade:
- bitcoin to v0.31.0
- miniscript to v11.0.0
Note: The bitcoin upgrade includes improvements to the
`Transaction::weight()` function, it appears those guys did good, we
no longer need to add the 2 additional weight units "just in case".
fix(electrum)!: Remove `seen_at` param from `into_tx_graph`
and `into_confirmation_time_tx_graph`, since now it makes
sense to use `TxGraph::update_last_seen_unconfirmed`.
Also, use `update_last_seen_unconfirmed` in examples for
electrum/esplora. We show how to update the last seen
time for transactions by calling `update_last_seen_unconfirmed`
on the graph update returned from a blockchain source, passing
in the current time, before applying it to another `TxGraph`.
That accepts a `u64` as param representing the latest timestamp
and internally calls `insert_seen_at` for all transactions in
graph that aren't yet anchored in a confirmed block.
These methods allow us to query for checkpoints contained within the linked list by height and height range. This is useful to determine checkpoints to fetch for chain sources without having to refer back to the `LocalChain`.
Currently this is not implemented efficiently, but in the future, we will change `CheckPoint` to use a skip list structure.
### Notes to the reviewers
Please refer to the conversation in #1354 for more details. In summary, both `TxGraph::missing_heights` and `tx_graph::ChangeSet::missing_heights_from` are problematic in their own ways. Additionally, it's a better API for chain sources if we only need to lock our receiving structures twice (once to obtain initial state and once for applying the update). Instead of relying on methods such as `EsploraExt::update_local_chain` to get relevant checkpoints, we can use these query methods instead. This allows up to get rid of `::missing_heights`-esc methods and remove the need to lock receiving structures in the middle of the sync.
### Changelog notice
* Added `get` and `range` methods to `CheckPoint` (and in turn, `LocalChain`). This simulates an API where we have implemented a skip list of checkpoints (to implement in the future). This is a better API because we can query for any height or height range with just a checkpoint tip instead of relying on a separate checkpoint index (which needs to live in `LocalChain`).
* Changed `LocalChain` to have a faster `Eq` implementation. We now maintain an xor value of all checkpoint block hashes. We compare this xor value to determine whether two chains are equal.
* Added `PartialEq` implementation for `CheckPoint` and `local_chain::Update`.

Continuation of #1115.
Closes #1036.
* Change deprecated `max_satisfaction_weight` to `max_weight_to_satisfy`
* Remove `#[allow(deprecated)]` flags
### Notes to the reviewers
I've changed all `max_satisfaction_weight()` to `max_weight_to_satisfy()` in `Wallet.get_available_utxo()` and `Wallet.build_fee_bump()`. Checking the docs on the `miniscript` crate for `max_weight_to_satisfy` has the following note:
We are testing if the underlying descriptor `is.segwit()` or `.is_taproot`,
then adding 4WU if true or leaving as it is otherwise.
Another thing, we are not testing in BDK tests for legacy (pre-segwit) descriptors.
Should I also add them to this PR?

This PR makes `TxGraph` store transactions as `Arc<Transaction>`.
`Arc<Transaction>` can be shared between the chain-source and receiving structures. This allows the chain-source to keep the already-fetched transactions (save bandwith) and have a shared pointer to the transaction (save memory).
Our current logic to avoid re-fetching transactions is to refer back to the receiving structures. However, this means an additional round of locking our receiving structures.
### Notes to the reviewers
This will make more sense once I update the esplora/electrum chain sources to make use of both #1369 and this PR. The result would be chain sources which would only require locking the receiving structures twice (once for initiating the update, and once for applying the update).

feat(chain)!: wrap `TxGraph` txs with `Arc`
Wrapping transactions as `Arc<Transaction>` allows us to share
transactions cheaply between the chain-source and receiving structures.
Therefore the chain-source can keep already-fetched transactions (save
bandwidth) and have a shared pointer to the transactions (save memory).
This is better than the current way we do things, which is to refer back
to the receiving structures mid-sync.
`TestEnv` is extracted into its own crate with `electrsd` support added so that `TestEnv` can also serve `esplora` and `electrum`.
The tests in the `esplora` crate have also been updated to use `TestEnv`.
The `tx_can_become_unconfirmed_after_reorg()` test in `test_electrum` suggests that the electrum issue where a reorged tx would be stuck at confirmed does not exist anymore.
### Notes to the reviewers
The code for `tx_can_become_unconfirmed_after_reorg()` was adapted from the same test in `bitcoind_rpc/test_emitter`. This electrum version of the test requires extra review, as I am uncertain if I used the API efficiently.

We currently allow removing `partial_sigs` from a finalized PSBT, which is relevant to non-taproot inputs, however taproot related PSBT fields were left in place despite the recommendation of BIP371 to remove them once the `final_script_witness` is constructed. This can cause confusion for parsers that encounter extra taproot metadata in an already satisfied input.

This follows a similar approach to #1141 namely to remove `FeeRate` from `bdk::types` and instead defer to the upstream implementation for all fee rates. The idea is that making the switch allows BDK to benefit from a higher level abstraction, leaving the implementation details largely hidden.
As noted in #774, we should avoid extraneous conversions that can result in deviations in estimated transaction size and calculated fee amounts, etc. This would happen for example whenever calling a method like `FeeRate::to_sat_per_vb_ceil`. The only exception I would make is if we must return a fee rate error to the user, we might prefer to display it in the more familiar sats/vb, but this would only be useful if the rate can be expressed as a float.
### Notes to the reviewers
`bitcoin::FeeRate` is an integer whose native unit is sats per kilo-weight unit. In order to facilitate the change, a helper method `feerate_unchecked` is added and used only in wallet tests and psbt tests as necessary to convert existing fee rates to the new type. It's "unchecked" in the sense that we're not checking for integer overflow, because it's assumed we're passing a valid fee rate in a unit test.
Potential follow-ups can include:
- [x] Constructing a proper `FeeRate` from a `u64` in all unit tests, and thus obviating the need for the helper `feerate_unchecked` going forward.
- [x] Remove trait `Vbytes`.
- Consider adding an extra check that the argument to `TxBuilder::drain_to` is within "standard" size limits.
- Consider refactoring `coin_selection::select_sorted_utxos` to be efficient and readable.
closes #1136
### Changelog notice

This method was not used (so it was untested) and it was not working. This fixes it.
The old implementation used `.next_store_index` which returned the keychain's last index stored in `.inner` (which include lookahead spks). This is WRONG because `.replenish_lookahead` needs the difference from last revealed.

There are several instances in the code where we allow clippy lints that would otherwise be flagged during regular checks. It would be preferable to minimize the number of "clippy allow" attributes either by fixing the affected areas or setting a specific configuration in `clippy.toml`. In cases where we have to allow a particular lint, it should be documented why the lint doesn't apply.
For context see https://github.com/bitcoindevkit/bdk/issues/1127#issuecomment-1784256647 as well as the commit message details.
One area I'm unsure of is whether `Box`ing a large error in 4fc2216 is the right approach. Logically it makes sense to avoid allocating a needlessly heavy `Result`, but I haven't studied the implications or tradeoffs of such a change.

`EntryIter`.
This PR removes the routines `get_checksum` and `get_checksum_bytes` (in the bdk crate, descriptor/checksum.rs), which have been deprecated in 0.24.0. Consequently, the routine `calc_checksum_bytes_internal` is consolidated into `calc_checksum_bytes`, as the boolean parameter `exclude_hash` is not needed anymore. See also the two TODOs in the touched file.
### Notes to the reviewers
In the second commit, the signature of the function `calc_checksum_bytes` slightly changes, as the `desc` parameter now is declared as `mut`, in order to change the local variable within the function. My rust experience is rather limited, so I'm not sure if this is a problem for users. IIUC, this is comparable to changing a pass-by-value parameter in C++ from `const std::string desc` to `std::string desc`, which is relevant only for the function implementation, but doesn't change the interface.
