Fix disconnectSync getting ignored

If using xhr-polling and a browser closes a tab or window, the
disconnectSync in the socket.io-client method is called which sends an
XHR request to the server indicating a disconnect. This line would cause
that to be ignored and so the server would have to wait for a timeout to
mark them as disconnect. This was possibly because it was sent from a
different tcp socket than the current connection.

Fix infinite recursion in Websocket parsers.

If a client is feeding messages faster than server can handle them, infinite
recursion occurs.  Basically, the "overflow" data gets added to the parser and
it immediately parses a new message.

The fix pushes the processing of the next message (in this edge case) onto the
event queue.  This prevents the stack from recursing indefinitely.  This also
prevents a fast client from starving other clients.
