* Hide internal structure of OverlayChanges

* Fix tests for OverlayChanges refactor

* Do not clone pending changes

Discarding prospective changes should be equivalent as a state machine
is not to be called with peding changes.

This will be replaced by a storage transaction that is rolled back before
executing the call the second time removing this constraint.

* Doc fixes

* Remove overlong line

* Revert "Do not clone pending changes"

This reverts commit 4799491f4ac16f8517287a0fcf4a3f84ad56f46e.

* Remove redundant type annotation

* Avoid changing the storage root in tests

* Preserve extrinsic indices in trie build test

This is only for consistency and does not impact the result.

* Make `Digest` support `StorageAppend`

This adds support for `StorageAppend` to `Digest`. Digest is just a
wrapper around a `Vec` and we abuse the fact that SCALE does not puts
any special marker into the encoding for structs. So, we can just append
to the encoded Digest. A test is added that ensures, if the `Digest`
format ever changes, we remove this optimization.

to catch future regressions.

* Expose that `BasicQueue` expects blocking spawn

Up to now `BasicQueue` expected a closure that to spawn a `Future`.
This was expected to be a closure that spawns a blocking future.
However, this wasn't documented anywhere. This pr introduces a new trait
`SpawnBlocking` that exposes this requirement to the outside.

* Feedback

* Use header cache for state_at

* Fixed warnings

* Update client/db/src/lib.rs
