* Prune discarded blocks immediately

* state-db refactoring part 1

* Some renames

* Get rid of pending state

* Revert "Prune discarded blocks immediately"

This reverts commit b60d98c569e8af18d99087da93f0911d4f24006e.

* Cleanup

* Make clippy happy

* Minor changes

* `payment_queryInfo`: Make it work with `WeighV2`

The runtime api for querying the payment info depends on the `Weight` type and broke for old
runtimes that still use the `WeighV1`. This pull requests fixes this by:

1. Bumping the version of the runtime api.
2. Making the node side code use the correct runtime api function depending on the version of the
runtime api.
3. Make the RPC always return `WeighV1`.

Users of the api should switch to `state_call` and decide based on the version of the runtime api
which `Weight` type is being returned.

* Fix tests

* Review comment

With `StateVersion::V1` values over a certain size are not inlined and being put into the backend
with their own hash. When accessing a value in the trie with a recorder, we check if the value is maybe already
recorded and thus, we can check the cache. To check if a value is already recorded, we use the key
of the value to differentiate them. The problem is when there are multiple tries, like multiple
child tries that all have different values under the same key. Before this pull request we didn't
have differentiated for which trie we already had recorded a (key, value) pair. This is now done by also taking
the storage root into account in the recorder to differentiate the different (key, value) pair in
the tries.

* Pipeline with ci image with rust 1.65

* fix tests

* use image with sha

* Do not update peer information if ancestor search is in progress

If block announcement is received from a peer while ancestor search
for that same peer is still in progress, do not update the peer's best
hash and best number as that causes the ancestor search to yield
different information from what was expected and can cause, for example,
a fork of lower height not be be downloaded.

* Block until peers are in sync

It changes &Block::Hash argument to Block::Hash.

We do not execute enactment phase of maintain procedure, but we do
