[beta] Backports (#8558)

* Fetching logs by hash in blockchain database (#8463)

* Fetch logs by hash in blockchain database

* Fix tests

* Add unit test for branch block logs fetching

* Add docs that blocks must already be sorted

* Handle branch block cases properly

* typo: empty -> is_empty

* Remove return_empty_if_none by using a closure

* Use BTreeSet to avoid sorting again

* Move is_canon to BlockChain

* typo: pass value by reference

* Use loop and wrap inside blocks to simplify the code

Borrowed from https://github.com/paritytech/parity/pull/8463#discussion_r183453326

* typo: missed a comment

* Pass on storage keys tracing to handle the case when it is not modified (#8491)

* Pass on storage keys even if it is not modified

* typo: account and storage query

`to_pod_diff` builds both `touched_addresses` merge and storage keys merge.

* Fix tests

* Use state query directly because of suicided accounts

* Fix a RefCell borrow issue

* Add tests for unmodified storage trace

* Address grumbles

* typo: remove unwanted empty line

* ensure_cached compiles with the original signature

* Update wasmi and pwasm-utils (#8493)

* Update wasmi to 0.2

New wasmi supports 32bit platforms and no longer requires a special feature to build for such platforms.

* Update pwasm-utils to 0.1.5

* Show imported messages for light client (#8517)

* Enable WebAssembly and Byzantium for Ellaism (#8520)

* Enable WebAssembly and Byzantium for Ellaism

* Fix indentation

* Remove empty lines

* Don't panic in import_block if invalid rlp (#8522)

* Don't panic in import_block if invalid rlp

* Remove redundant type annotation

* Replace RLP header view usage with safe decoding

Using the view will panic with invalid RLP. Here we use Rlp decoding directly which will return a `Result<_, DecoderError>`. While this path currently should not have any invalid RLP - it makes it safer if ever called with invalid RLP from other code paths.

* Node table sorting according to last contact data (#8541)

* network-devp2p: sort nodes in node table using last contact data

* network-devp2p: rename node contact types in node table json output

* network-devp2p: fix node table tests

* network-devp2p: note node failure when failed to establish connection

* network-devp2p: handle UselessPeer error

* network-devp2p: note failure when marking node as useless
