The QMP exchange to exit capabilities negotiation mode and enter command mo= de can only be performed once after the monitor connection is established. Move responsibility for entering QMP command mode into the qemuProcessQMP code so multiple functions can issue QMP commands in arbitrary orders. This also simplifies the functions using the connection provided by qemuProcessQMPStart to issue QMP commands. Test code now needs to call qemuMonitorSetCapabilities to send the message to switch to command mode because the test code does not use the qemuProcessQMP command that internally calls qemuMonitorSetCapabilities.
