* disconnect peers that send non-hello messages during initial hello
step
* fix devp2p protocol version - 4 because we don't implement snappy
(yet) - this is cosmetic since this particular version field is not
actually being used
* fix ack message length checking
* move RLPx transport code to separate module, annotate with asyncraises
* increase max RLPx message size to 16mb, per EIP-706
* make sure both accept/connect timeout after 10s
* aim to log every connection attempt once at debug level
* make capability-id/context-id check more accurate
* disallow random messages before hello
Support for previous versions was
[removed](7194c847b6)
from geth in 2021 after other clients had migrated - should be safe to
remove here also.
* fix snappy detection - it should use the hello version, not the RLPx
handshake
* simplify generation of auth messages
* pad 100-300 bytes like spec suggests
TODO: error handling is all over the place - will be addressed in a
follow-up PR
`eth_types` is being imported from many projects and ends up causing
long build times due to its extensive import lists - this PR starts
cleaning some of that up by moving the chain DB and RLP to their own
modules.
this PR also moves `keccakHash` to its own module and uses it in many
places.
why:
For some reason, Nethermind insists on sending chunked messages to
the syncing peer. Unfortunately, for the test networks the Nethermind
modes are the importent ones as they speak eth/65 as well while others
like Geth only support eth/66 which is not implemented here, yet.
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.
* 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
* 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
