Before this commit the query were send randomly to any peer until there
is a reply (for a query that got no result it was an issue, for other
queries it was quering multiple times the same peers).
After this commit the first query is random but next queries
follows hashmap iterator order.
Test no_capability was broken by this commit (the pending query was
removed).

* Cli option `on_demand_nb_retry` for maximum number of retry when doing
on demand query in light client.
* Missing test update for previous commit
* Add a timeout (only when there is no peer to query), that way we do not
set number of query to minimum current number peer or configured number
of query : that way capability test was restored.

reported at rpc level : choice of rpc error code error might not be
right.

- renaming nb_retry params to 'on-demand-retry-count'

* Enforce limit on header range length in light client logs request.
* Fix light request tests after struct change.

* 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
* Replace Rlp with UntrustedRlp and unsafely unwrap
All Rlp methods return Result<_,DecoderError> now, so for this first
pass each will be marked with `expect("TODO")`. In the next pass we can
categorise figure out how to handle each case.
* Handle DecoderError for tendermint message
* Unwrap rlp results in TestBlockcChainClient
Rlp should be valid since created manually in tests
* Replace `use rlp::*` with explicit imports
* Remove rlp decode unwraps from light cli request
* Structured rlp encoding for curr best and latest in header chain
* Propogate decoder errors from send_packet
* Fix body uncles rlp index
* Use BodyView in sync and `expect` rlp errors
* Revert bbf28f removing original Rlp for this phase
This can be done again in the next phase, in order that we can leave the ethcore views unchanged
* Restore legacy Rlp and UntrustedRlp
Use legacy Rlp for ethcore views. Will redo replacing Rlp with UntrustedRlp in a subsequent PR
* Fix tests
* Replace boilerplate Encodable/Decodable with derive
* Use BlockView instead of Rlp, remove unwrap
