It's a bit long, but I think it's worth writing WEB_SOCKET out, to make the code
clearer.  Otherwise, looks a bit too much like Windows socket errors for my
tastes (They actually use WSA, but look kinda similar).  Also, Google style
guide generally discourages abbreviations.

Wonder if it makes sense to move these to their own file.  Think they'll be
useful in files that don't need access to WebSocketFrameHeader?

Done.
