Cancel http read only queries if client socket goes away
To check the socket status, try to read one byte from socket in a
non-blocking way:
      0 - client closed the connection
   >= 1 - client send more data, we are ignoring this case for now
timeout - normal case, client is waiting for response
    ... - socket broken?

Dirty, but should do the job. Limiting to readonly queries as I don't
want to mess with alter queries / insert select and others.
