* 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

* Replace spaces with tabs in new file

* Add doc tests for creating views with macro

* Update rlp docs to reflect removing of UntrustedRlp

* Replace UntrustedRlp usages in private-tx merge
