[bugfix] fix possible mutex lockup during streaming code (#2633)
* rewrite Stream{} to use much less mutex locking, update related code

* use new context for the stream context

* ensure stream gets closed on return of writeTo / readFrom WSConn()

* ensure stream write timeout gets cancelled

* remove embedded context type from Stream{}, reformat log messages for consistency

* use c.Request.Context() for context passed into Stream().Open()

* only return 1 boolean, fix tests to expect multiple stream types in messages

* changes to ping logic

* further improved ping logic

* don't export unused function types, update message sending to only include relevant stream type

* ensure stream gets closed 🤦

* update to error log on failed json marshal (instead of panic)

* inverse websocket read error checking to _ignore_ expected close errors
