`PersistBackend::is_empty` is removed. Instead, `load_from_persistence`
returns an option of the changeset. `None` means persistence is empty.
This is a better API than a separate method. We can now differentiate
between a persisted single changeset and nothing persisted.
`Store::aggregate_changeset` is refactored to return a `Result` instead
of a tuple. A new error type (`AggregateChangesetsError`) is introduced
to include the partially-aggregated changeset in the error. This is a
more idiomatic API.
991cb77b6fbeedbf52d1bd9aa6b3d680f8269969 fix(chain): filter coinbase tx not in best chain (Wei Chen)
Pull request description:
### Description
Fixes#1144.
Coinbase transactions cannot exist in the mempool and be unconfirmed. `TxGraph::try_get_chain_position` should always return `None` for coinbase transactions not anchored in best chain.

Coinbase transactions cannot exist in the mempool and be unconfirmed.
`TxGraph::try_get_chain_position` should always return `None` for coinbase
transactions not anchored in best chain.
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.
* `CheckPoint::from_header` allows us to construct a checkpoint from
block header.
* `CheckPoint::into_update` transforms the cp into a
`local_chain::Update`.

...try_get_chain_pos
In try_get_chain_pos, when we notice that a transaction is not included
in the best chain, we check the transactions in mempool to find
conflicting ones, and decide based on that if our transaction is still
in mempool or has been dropped.
This commit adds a check for transactions conflicting with the
unconfirmed ancestors of our tx.

cc1a43c495639f0dbe6da52501cb48f17b8cbbd2 fix: SpkIterator::new_with_range takes wildcards.. ..into account (Daniela Brozzoni)
Pull request description:
### Description
When you pass a non-wildcard descriptor in `new_with_range`, we make
sure that the range length is at most 1; if that's not the case, we
shorten it.
We would previously use `new_with_range` without this check and with a
non-wildcard descriptor in `spks_of_all_keychains`, this meant creating
a spkiterator that would go on producing the same spks over and over
again, causing some issues with syncing on electrum/esplora.
To reproduce the bug, run in `example-crates/example_electrum`:
```
cargo run "sh(wsh(or_d(c:pk_k(cPGudvRLDSgeV4hH9NUofLvYxYBSRjju3cpiXmBg9K8G9k1ikCMp),c:pk_k(cSBSBHRrzqSXFmrBhLkZMzQB9q4P9MnAq92v8d9a5UveBc9sLX32))))#zp9pcfs9" scan
```
### Changelog notice
- Fixed a bug where `KeychainTxOutIndex::spks_of_all_keychains`/`KeychainTxOutIndex::spks_of_keychain` would return an iterator yielding infinite spks even for non-wildcard descriptors.
