QUIC: improved path validation.
Previously, path was considered valid during arbitrary selected 10m timeout
since validation. This is quite not what RFC 9000 says; the relevant
part is:
An endpoint MAY skip validation of a peer address if that
address has been seen recently.
The patch considers a path to be 'recently seen' if packets were received
during idle timeout. If a packet is received from the path that was seen
not so recently, such path is considered new, and anti-amplification
restrictions apply.
