* 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.

* Split out ReadRequest and ReadResponse state service enums
* Simplify RPC test vectors
* Split state requests into Request and ReadRequest
* Make zebra-rpc use the new state ReadRequest
* Add request metrics to ReadStateService
Add a field to distinguish StateService and ReadStateService metrics.
Add missing StateService request metrics.
* Refactor state transaction lookup so it can be shared between services
* Implement ReadState Request::Transaction
* Revert "Drop the Chain watch channel lock before accessing the finalized state"
This reverts commit 8870944d1323fc31e2d009b9938623de6fcbe50f.
* Add a WatchReceiver wrapper that always clones the borrowed watch data
This avoids deadlocks, by holding the read lock for as short a time as possible.
* Drop the shared Arc<Chain>s as quickly as possible
This reduces memory usage.
* Make read::block more flexible, by accepting any AsRef<Chain>
* Make the block method docs consistent
* Avoid livelocks by explicitly dropping the borrow after the clone
* Use the read-only state service for RPCs
* Refactor non-finalized block lookup into Chain
* Implement the read-only state block request
* Drop the Chain watch channel lock before accessing the finalized state
* Add state service module docs and cleanup
* Move and add finalized state methods
* Add chain and non-finalized state methods
* Cleanup methods and imports
* Create a ReadStateService type
* Add a stub service implementation
* Add a TODO
* Update ReadStateService request stubs with RPC names and tickets
* Documentation updates
* Make RPC State generic bounds accept a buffered state and a read-only state
* Doc updates
* Add missing proptest-impl feature in RPC dev dependencies
* Move the legacy chain check to the `check` module
And move `populated_state` to the `arbitrary` module.
* Cleanup imports
* Document the state service struct
* Split state block iter into its own module
* feature(rpc): start adding a `getblock` method

* 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`.

* feat(log): log the state tip height as part of sync progress logs
* fix(log): downgrade some verbose state logs to debug
* feat(log): log successful gossiped block verification at info level
These logs help us diagnose slow progress near the tip.
There won't be very many of these logs,
because they only happen near the tip.
* fix(log): spawn top-level tasks within the global Zebra tracing span
* fix(log): spawn blocking top-level tasks within the global Zebra tracing span
