1) Update the Print2 Protocol to only use arguments of type BASE_LIST. Since this is a change to the protocol definition, the GUID has also been updated. 2) Update the implementation of DxePrintLibPrint2Protocol for the update definition of the Print2 Protocol. Since the PrintLib does contain APIs that use VA_LIST, this library must convert arguments of type VA_LIST to arguments of type BASE_LIST prior to calling the Print2 Protocol services. 3) Update the implementation of PrintDxe to match the updated Print2 Prootocol git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@8405 6f19259b-4bc3-4df7-8a09-765794883524
