This changes the challenge resend logic again to use the existing
`ChallengeData` field of `v5wire.Whoareyou` instead of storing a second
copy of the packet in `Whoareyou.Encoded`. It's more correct this way
since `ChallengeData` is supposed to be the data that is used by the ID
verification procedure.
Also adapts the cross-client test to verify this behavior.
Follow-up to #31543
This adds the test description text to the output, instead of keeping it
as a Go comment. Logs are visible in the hive UI where these tests run,
while Go comments are not.
* p2p/discover: add more packet information in logs
This adds more fields to discv5 packet logs. These can be useful when
debugging multi-packet interactions.
The FINDNODE message also gets an additional field, OpID for debugging
purposes. This field is not encoded onto the wire.
I'm also removing topic system related message types in this change.
These will come back in the future, where support for them will be
guarded by a config flag.
* p2p/discover/v5wire: rename 'Total' to 'RespCount'
The new name captures the meaning of this field better.
