Document why we do a UTXO check that looks redundant (#5106)
Also inline the call stack for the check, so it is efficient.

feat(state): Send treestate from non-finalized state to finalized state (#4721)
* Add history trees for each height in non-fin state

* Refactor formatting

* Pass the treestate to the finalized state

I created a new structure `FinalizedBlockWithTrees` that wraps the
treestate and the finalized block. I did that because the original
`FinalizedBlock` is `Eq`, but `HistoryTree` can't be `Eq`.

This makes Zebra faster because:

1. The finalized state doesn't retrieve the treestate from the disk if
the non-finalized state supplies it.

2.The finalized state doesn't recompute the treestate if the
non-finalized state supplies it.

* Check block commitment before updating hist tree

* Store Sprout commitment trees in non-fin state

* Send trees for the root block to fin-state

When committing a block and sending the treestate from the non-finalized
state to the finalized state, Zebra was sending trees that correspond to
the tip block instead of trees that correspond to the root block of the
best chain. This commit fixes that.

* Refactor doc comments

* Refactor block finalization

change(state): Remove `active_value` field from `ChainTipSender` (#4175)
* Refactor instrumented records in `ChainTipSender`

Record the fields using a helper method. This reduces duplicate code and
prepares for removing the `active_value` field from the type, because
the replacement for it has to be atomically read to avoid a deadlock
when reading from the `watch::Sender` endpoint.

* Replace `active_value` field with sender borrow

Now that Tokio has been updated to a version in which `watch::Sender`
has a `borrow` method, we can remove the `active_value` field.

To prevent a deadlock like the one that happened with the synchronizer
some time ago, the method instrumentation was slightly refactored to
have the fields recorded in helper methods that avoid obtaining a
read-lock twice.

* Remove some `TODO` comments

They are resolved with the current changes.

* Refactor to avoid obtaining current `Span` twice

This is a minor optimization to remove an unnecessary second call to
`tracing::Span::current()`.

* Add a comment about preventing dead-locks

Explain why a binding can't be created for the old tip reference.

* Retry after log ssh failures in full sync test

* Use a `SerializedBlock` type to help serializing blocks (#3725)

* Create a `SerializedBlock` helper type

Create a type that can be used as a byte slice, but is guaranteed to
represent a valid block.

* Use `into_iter` instead of `iter`

There's no need to borrow the elements, they can be moved out directly.
This will be necessary because `&Arc<T>` doesn't implement `Borrow<T>`,
so a `SerializedBlock` can't be built directly from an `&Arc<Block>`.

* Use `SerializedBlock` in `GetBlock`

Make the type stricter to avoid storing possibly invalid values. The
bytes are still serialized as a hexadecimal string, through the usage of
`hex`.

The `serde::Deserialize` can't be derived because `hex` requires the
type to also implement `FromHex`.

Estimate network chain tip height based on local node time and current best tip (#3492)
* Remove redundant documentation

The documentation was exactly the same as the documentation from the
trait.

* Calculate a mock time block delta for tests

Simulate a block being added to the chain with a random block time based
on the previous block time and the target spacing time.

* Add a `time` field to `ChainTipBlock`

Store the block time so that it's ready for a future chain that allows
obtaining the chain tip's block time.

* Add `ChainTip::best_tip_block_time` method

Allow obtaining the bes chain tip's block time.

* Add method to obtain both height and block time

Prevent any data races by returning both values so that they refer to
the same chain tip.

* Add `NetworkUpgrade::all_target_spacings` method

Returns all the target spacings defined for a network.

* Create a `NetworkChainTipEstimator` helper type

Isolate the code to calculate the height estimation in a new type, so
that it's easier to understand and doesn't decrease the readability of
the `chain_tip.rs` file.

* Add `ChainTip::estimate_network_chain_tip_height`

This is more of an extension method than a trait method. It uses the
`NetworkChainTipHeightEstimator` to actually perform the estimation, but
obtains the initial information from the current best chain tip.

* Fix typo in documentation

There was an extra closing bracket in the summary line.

* Refactor `MockChainTipSender` into a separate type

Prepare to allow mocking the block time of the best tip as well as the
block height.

* Allow sending mock best tip block times

Add a separate `watch` channel to send the best tip block times from a
`MockChainTipSender` to a `MockChainTip`.

The `best_tip_height_and_block_time` implementation will only return a
value if there's a height and a block time value for the best tip.

* Fix off-by-one height estimation error

Use Euclidean division to force the division result to round down
instead of rounding towards zero. This fixes an off-by-one error when
estimating a height that is lower than the current height, because the
fractionary result was being discarded, and it should have forced the
height to go one block back.

* Fix panics on local times very far in the past

Detect situations that might cause the block height estimate to
underflow, and return the genesis height instead.

* Fix another off-by-one height estimation error

The implementation of `chrono::Duration::num_seconds` adds one to the
number of seconds if it's negative. This breaks the division
calculation, so it has to be compensated for.

* Test network chain tip height estimation

Generate pairs of block heights and check that it's possible to estimate
the larger height from the smaller height and a displaced time
difference.

2. Route peer requests based on missing inventory (#3465)

* refactor(network): move the inventory filter into an async function

* feat(network): avoid routing requests to peers that are missing inventory

* test(network): advertised routing is independent of numeric address value

* test(network): peer set fails requests if all ready peers are missing that inventory

* fix(clippy): needless-borrow in the peer set

* fix(lint): remove redundant trailing commas in macro calls

There is no clippy lint for this, maybe because some macros
are sensitive to trailing commas.
(But not the ones changed in this commit.)

Fix deadlock in chain tip watch channel (#3378)
* Avoid sequential borrows in `LatestChainTip`

Calling `watch::Receiver::borrow` more than once in the same scope can
cause a deadlock. The instrumented methods were calling `borrow` twice
to record instrumented fields.

This refactors things to ensure `borrow` is only called once to record
the fields and perform any actions with the chain tip block.

* Remove `borrow()` calls in `ChainTipChange`

Refactor to use a `LatestChainTip` instance instead, which safely
protects the internal `watch::Receiver` so that it is not borrowed more
than once in the same scope.

* Add a paragraph to the Asynchronous guide

Warn against using two borrow guards in the same scope, and describe why
that can lead to a deadlock.
