A first step in cleaning up RLP, which has lots of interesting issues -
the next step would be to clean up the exception handling as well
(Resultify?)
* remove `RlpNode` (unused)
* single-pass parsing for most functionality via RlpItem
* stricter conformance to spec
* remove float support
* warn about signed integers
* raise on invalid RLP earlier
* avoid several pointless allocations, in particular in `listLen`,
`listElem` etc
* include spec docs
* Refactor p2pProtocol internals
* Attempt to fix rlp crash with Nim v2 (#658)
* Attempt to fix rlp crash with Nim v2
* Fix test_ecies for nim v2
* Reduce compiler warnings
* Resolve ambiquity in testutils
* Disable nim devel continue-on-error
`blobGasUsed` was not mentioned in `test_rlp_codec` test names, despite
being used. Further, update the idea of `genOptionalFieldsValidation`
to also check for `blobGasUsed`, and fix the check to catch unsupported
combinations of optional fields.
Instead of patching BlockHeader or BlockBody codec
each time it get additional optional fields,
this PR make the rlp codec automatically handle
optional fields. Thus rlp codec overloading of
EthBlock, BlockHeader, and BlockBody can be removed.
Currently only setting `--styleCheck:hint` as there are some
dependency fixes required and the compiler seems to trip over the
findnode MessageKind, findnode Message field and the findNode
proc. Also over protocol.Protocol usage.
For a long time this caused invalid RLP parsing of `NewBlock` messages in the
`eth` protocol.
The `rlpInline` pragma was accepted but had no effect. We could implemented
it, but it doesn't seem worth doing, with tests etc, as there's only one user
which has been fixed another way.
With `NewBlock`, whenever a peer sent us `NewBlock`, we'd get an RLP decoding
error, and disconnected the peer thinking it was the peer's error.
These messages are sent often by good peers, so whenever we connected to a
really good peer, we'd end up disconnecting within a minute due to this. This
went unnoticed for years, as we stayed connected to old peers which have no new
blocks, and we weren't looking at peer quality, disconnect reasons or real-time
blockchain updates anyway.

* Add build_dcli target and add it to CI
* Fix local imports for dcli
* And use local imports for all other files too
* Use local imports in tests and rlpx protocols
