I noticed that WebSocket spec updated to not inlcude framing overhead in
I tried to implement it in WebKit, but found it make hard to implement
correctly. https://bugs.webkit.org/show_bug.cgi?id=35571
It's easy after WebSocket is closed (just add length of message), but while
it's open, we'll manage buffer including frame bytes and underlying socket
will write arbitrary length of the buffer (may not be on frame boundary)
To get bufferdAmount correctly without framing overhead, we need to parse
the buffer again.  It's not light operation and it's challenge to make it
I think including frame overhead is much easier.
Could you revert it?
