Instead of inserting anchors and seen_at timestamp in the same method,
we have three separate methods. This makes the API easier to understand
and makes `IndexedTxGraph` more consistent with the `TxGraph` API.
For `IndexedTxGraph`:
- Remove `InsertTxItem` type (this is too complex).
- `batch_insert_relevant` now uses a simple tuple `(&tx, anchors)`.
- `batch_insert` is now also removed, as the same functionality can be
done elsewhere.
- Add internal helper method `index_tx_graph_changeset` so we don't need
to create a seprate `TxGraph` update in each method.
- `batch_insert_<relevant>_unconfirmed` no longer takes in an option of
last_seen.
- `batch_insert_unconfirmed` no longer takes a reference of a
transaction (since we apply all transactions anyway, so there is no
need to clone).
For `TxGraph`:
- Add `batch_insert_unconfirmed` method.
added
- Wallet::insert_txout function to allow inserting foreign TxOuts
- test to verify error when trying to calculate fee with missing foreign utxo
- test to calculate fee with inserted foreign utxo
updated
- docs for Wallet::calculate_fee, Wallet::calculate_fee_rate, and TxGraph::calculate_fee
with note about missing foreign utxos
Added
- Wallet::sent_and_received function
- Wallet::calculate_fee and Wallet::calculate_fee_rate functions
- Wallet::error::CalculateFeeError
BREAKING CHANGES:
Removed
- TransactionDetails struct
Changed
- Wallet::get_tx now returns CanonicalTx instead of TransactionDetails
- TxBuilder::finish now returns only a PartiallySignedTransaction
Although there is *some* code to handle multipath keys inside bdk,
it's all untested, and from a few quick tests it
seems that it's pretty easy to find buggy edge cases.
Better to deny multipath descs for now, and revisit the
decision once we work on supporting multidescriptor wallets.

Pull request description:
Fixes#997
Replaces #1002
### Description
This PR changes the `LocalChain` implementation to have blocks stored as a linked-list. This allows the data-src thread to hold a shared ref to a single checkpoint and have access to the whole history of checkpoints without cloning or keeping a lock on `LocalChain`.
The APIs of `bdk::Wallet`, `esplora` and `electrum` are also updated to reflect these changes. Note that the `esplora` crate is rewritten to anchor txs in the confirmation block (using the esplora API's tx status block_hash). This guarantees 100% consistency between anchor blocks and their transactions (instead of anchoring txs to the latest tip). `ExploraExt` now has separate methods for updating the `TxGraph` and `LocalChain`.
A new method `TxGraph::missing_blocks` is introduced for finding "floating anchors" of a `TxGraph` update (given a chain).
Additional changes:
* `test_local_chain.rs` is refactored to make test cases easier to write. Additional tests are also added.
* Examples are updated.
* Exclude example-cli `*.db` files in `.gitignore`.
* Rm duplicate `bdk_tmp_plan` module.
### Notes to the reviewers
This is the smallest possible division of #1002 without resulting in PRs that do not compile. Since we have changed the API of `LocalChain`, we also need to change `esplora`, `electrum` crates and examples alongside `bdk::Wallet`.
### Changelog notice
* Implement linked-list `LocalChain`. This allows the data-src thread to hold a shared ref to a single checkpoint and have access to the whole history of checkpoints without cloning or keeping a lock on `LocalChain`.
* Rewrote `esplora` chain-src crate to anchor txs to their confirmation blocks (using esplora API's tx-status `block_hash`).

Thank you @vladimirfomene for these suggestions.
* Rename `LocalUpdate::keychain` to `LocalUpdate::last_active_indices`.
* Change docs for `CheckPoint` to be more descriptive.
* Fix incorrect logic in `update_local_chain` for `EsploraExt` and
`EsploraAsyncExt`.

Pull request description:
### Description
This PR solves #836. This PR adds a P2TR
descriptor template and a BIP86 taproot
descriptor template. With this, users
can now create a taproot descriptor with templates.

Other changes:
* The `async-https` feature of `bdk_esplora` is no longer default.
* Rename `ObservedAs` to `ChainPosition`.
* Set temporary MSRV to 1.60.0 to compile all workspace members will all
features.
* `ElectrumUpdate::missing_full_txs` now returns a `Vec<Txid>` so we
don't keep a reference to the passed-in `graph`.
* `ElectrumUpdate::finalize*` methods now takes in `missing` txids
instead of `full_txs`. `Client::batch_transaction_get` is called
within the methods.
Other changes:
* `wallet::ChangeSet` is now made public externally. This is required as
a wallet db should implement `PersistBackend<wallet::ChangeSet>`.
This corresponds to `keychain::KeychainChangeSet` but for the redesigned
structures with `LocalChain`.
This structure is now used in `Wallet` as well as the examples.
This PR solves #836. This PR adds a P2TR
descriptor template and a BIP86 taproot
descriptor template. With this, users
can now create a taproot descriptor with templates.
When constructing the `Condition` struct we recursively call
`get_condition` on all the items in a threshold and short-circuit if
there's an error somewhere (for example, because the policy-path hasn't
been provided for a specific threshold).
This can cause issues when the user doesn't care about a subtree, because
we still try to call `get_condition` on all the items and fail if
something is missing, even if the specific subtree isn't selected and
won't be used later on.
This commit changes the logic so that we first filter only the `selected`
items, and then unwrap the error using the question mark. If errors
happened somewhere else they will be ignored, as it should.
