Refactor MuxId

[Nashatyrev]

There is some inconsistency with MuxId for Yamux: the StreamId for yamux is just a Long while stream id for Mplex is a pair of (Long, Boolean). So we need to abstract MuxId and make it consistent across both muxers

We also need to validate remote StreamId on remote stream opening (SYN for Yamux)

• Make MuxId abstract. Remove Mplex specific 'initiator' field
• Add remote SYN StreamId validation for Yamux
• Add YamuxHandler.goAwayPromise which handles GoAway error code.
• Abort connection when remote tries to open a stream with existing MuxId
• Adopt and add tests
