+Basic Ascii AvSPrintf() function named VSPrint(). VSPrint() enables very
+simple implemenation of SPrint() and Print() to support debug.
+
+You can not Print more than EFI_DRIVER_LIB_MAX_PRINT_BUFFER characters at a
+time. This makes the implementation very simple.
+
+VSPrint, Print, SPrint format specification has the follwoing form
+
+%type
+
+type:
+ 'S','s' - argument is an Unicode string
+ 'c' - argument is an ascii character
+ '%' - Print a %
