* Lots of println to figure out what eth_getBlockByNumber does/should do
* Remove debugging
* Print warnings when fetching pending blocks
When calling `eth_getBlockByNumber` with `pending`, we now print a deprecation warning and:
* if a pending block is found, use it to respond
* if no pending block is found, respond as if if was a request for `Latest`
Addresses issue #8703 (not sure if it's enough to close it tbh)
* Set the request index to that of the current request
When setting up the chain of (two) requests to look up a block by hash, the second need to refer to the first. This fixes an issue where the back ref was set to the subsequent request, not the current one. When the requests are executed we loop through them in order and ensure the requests that should produce headers all match up. We do this by index so they better be right.
In other words: off by one.

* Replace Rlp with UntrustedRlp in views, explicity unwrap with expect
First pass to get it to compile. Need to figure out whether to do this or to propogate Errors upstream, which would require many more changes to dependent code. If we do this way we are assuming that the views are always used in a context where the rlp is trusted to be valid e.g. when reading from our own DB. So need to fid out whether views are used with data received from an untrusted (e.g. extrernal peer).
* Remove original Rlp impl, rename UntrustedRlp -> Rlp
* Create rlp views with view! macro to record debug info
Views are assumed to be over valid rlp, so if there is a decoding error we record where the view was created in the first place and report it in the expect
* Use $crate in view! macro to avoid import, fix tests
* Expect valid rlp in decode functions for now
