Support for DevNull Console Out. This console uses memory buffers

arguments are optional and only returned if a non NULL pointer is passed in.
Arguments:
This - Protocol instance pointer.
Mode - Are we in text of grahics mode.
UgaExists - TRUE if UGA Spliter has found a UGA device
GopExists - TRUE if GOP Spliter has found a GOP/UGA device
StdInLocked - TRUE if StdIn device is keyboard locked
