http: OutgoingMessage streamlike

[ronag]

http OutgoingMessage is missing some methods, properties and behaviours to make it "truly" "streamlike":

• destroyed
• writableLength (http: OutgoingMessage stream properties #29018)
• writableHighWaterMark (http: OutgoingMessage stream properties #29018)
• writableCorked
• writableObjectMode (http: OutgoingMessage stream properties #29018)
• cork() (http: outgoing cork #29053)
• uncork() (http: outgoing cork #29053)
• ERR_STREAM_DESTROYED (http: align with stream.Writable #31818)
• instanceof Writable (issue http: OutgoingMessage instanceof Writable #28971)

Furthermore the destroy event ordering does not seem to be fully consistent with the stream implementation (needs further investigation).

Great initiative, definitely +1 to add all of these!

Is there some reason that OutgoingMessage is not an ancestor of Writable?
