qapi: introduce x-query-opcount QMP command
This is a counterpart to the HMP "info opcount" command. It is being added with an "x-" prefix because this QMP command is intended as an ad hoc debugging tool and will thus not be modelled in QAPI as fully structured data, nor will it have long term guaranteed stability. The existing HMP command is rewritten to call the QMP command. Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
