* 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

* update to error log on failed json marshal (instead of panic)
* inverse websocket read error checking to _ignore_ expected close errors
* [chore] Remove years from all license headers
Years or year ranges aren't required in license headers. Many projects
have removed them in recent years and it avoids a bit of yearly toil.
In many cases our copyright claim was also a bit dodgy since we added
the 2021-2023 header to files created after 2021 but you can't claim
copyright into the past that way.
* [chore] Add license header check
This ensures a license header is always added to any new file. This
avoids maintainers/reviewers needing to remember to check for and ask
for it in case a contribution doesn't include it.
* [chore] Add missing license headers
* [chore] Further updates to license header
* Use the more common // indentend comment format
* Remove the hack we had for the linter now that we use the // format
* Add SPDX license identifier
