* Handle the decodeAuthMessage error case separatly and log to trace
Garbage data on the TCP port (e.g. from port scanners) would
cause lots of error log messages, so log this to trace and get rid
of a (little) bit of exception usage in the process.
* Remove usage of result var in rlpxAccept and rlpxConnect
* Discv4: Add ENRRequest & ENRResponse msgs to avoid fails on these
Fix#499
These messages are not implemented yet however, but just ignored.
why:
Rlp errors throw exceptions which cause the dispatcher loop to
terminate the current session immediately.
details:
The DisconnectionReasonList message requires a single entry list.
Observed and now accepted deviations are:
Geth: single byte number
bor(a Geth fork): blobbed single entry list containing a number
The ENR code used to be solely exception based, and these
exceptions where a left-over of that. They are useless as later
calls use Result anyhow.
Additionally, they cause quite the performance loss because they
are used in the "common path" for the toTypedRecord call, e.g.
when reading the fields of ip6, tcp6 and udp6.
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.
toBytes for NodeId wasn't selected by compiler byt if it does
get selected, it will fail on the test cases due to the
countdown that is done in logDistance.
Set to toBytesBE properly now and do countup, that should make
it correct also for BE architecture.
Removed toBytes to avoid confusion and avoid this one being
selected ever. The only place toBytes for NodeId was used is in
sessions.nim makeKey func and there also the stint one
(thus native endianness) was selected in Nim 1.2.x.
Native endianness is fine there as it is only an internal
representation.
* Don't fail ENR decoding when value is an RLP list
* Store RLP raw list in the ENR field pair instead
* Add ENR kList FieldKind so lists can be treated differently
Treated differently now when printing out the ENR, mentioning
that it is a raw RLP list
* Allow for tcp/udp ports to always be configured
- Allow for an ENR to be build with tcp and udp ports also when
no IP address is provided
- In the address set-up always provide best efforttcp and udp ports
also when configuration of external ip (and/or ports) fails.
* Modify nodes verification
* Move nodes verification to separate module
By moving verification to separate module it can be re-used
in different contexts not only in discoveryv5.
It's been confirmed that the test fails if the Kademlia crash workaround isn't
in `findNode`, and passes with it there.

- use bitsPerHop (b) of 5
- small fix in resolve
- small fix in bucket split
* Discv5: More error handling improvements
- More results usage and raises pragma annotations
- Remove ENode related code and adjust Node object
- Misc.
* Add sendMessage and catch RlpError when decoding WhoAreYou
* Make the receive proc exception free
Except for `Exception` hah...
* Address review comments
* And another bunch of results and raises annotations
* Send Nodes Message also on 0 nodes and remove usage of broken require
* simplify some modules
* mark several modules with raises
* fix clearing of keys in auth.nim
* fix keyfile case dropping off
* fix keyfile stream storage
* uuid should be output in lowercase
* enode: simplify API
* avoid mix of exceptions and return codes
* introduce result
* use deprecated compatibility API to avoid big-bang refactoring
* loosely based on nim-libp2p secp as well as the rust-secp256k1 wrapper
* oh, boy does our secp256k1 wrapper need updating - we're _far_
behind...
