Fixes a missing CancelledError async raising on discv5 waitMessage
which would cause "Error set on a non-raising future".
Also moves some more results import away from stew.
* Fix chronos related deprecated warnings in discv5
* Fix chronos related deprecated warnings in uTP code
* Improve discv5 closeWait order of events and add noCancel
* 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
This allows for protocols build on top of discv5 to use the ENR
provided in the handshake directly, instead of having to rely
on requesting it from the discv5 routing table.
* Add metrics related to devp2p peer connections
* Avoid reconnecting to peers that just failed connection
- Add SeenTable to avoid reconnecting to peers immediately after
a failed connect. Depending on the failure, the amount of time is
different. This is similar to what is done in nimbus-eth2.
- Attempt to rework rlpxConnect at the same time, in order to
make sure that errors are properly handled. The current structure
is far from ideal, but it is hopefully a small step in the right
direction. To many oddities in there right now to really rework
rlpxConnect properply.
* Fix rlpx thunk fuzzer
The old code, which did it in sequence, made it take a very long
time to accumulate peers in the peer pool, particularly because
occasionally a connection-attempt would hang for a couple of minutes
before timing out.
* persist ENRs (parsed) from the discovery5 protocol
* filter fork_digest from eth2 data
* Update eth/p2p/discoveryv5/dcli.nim

- Fix two possible RangeErrors, due to negative seq allocation
in decodeAuthMessageEIP8 and in decodeAckMessageEIP8
- Set the minimum auth message size to AuthMessageEIP8Length,
in case there are clients that no longer add padding
- Add tests for invalid length cases
RLP Enum deserialization would currently not check if "hole values"
were attempted to be converted to the enum type. Now use
checkedEnumAssign and fail with RlpTypeMismatch on invalid values.
There is at least one occurance of an enum with holes in rlpx p2p:
DisconnectionReason. For this enum the issue could occur.
Also:
- Added enum RLP tests and rlpx p2p disconnect message tests to
test the DisconnectionReason with enum hole value.
- Fixed worse custom DisconnectionReason decoding occurance
in rlpx in waitSingleMsg proc where this issue could occur.
