i) BMM_FAKE_NV_DATA definition inconsistent in bm.vfr and BootMain.h
(EdkNt32Pkg\Dxe\PlatformBdsDxe\Generic\BootMaint\BootMain.h)
ii) Change some files’ EOL(end of line) format to DOS. Some file use even mixed style EOL.
(EdkModulePkg\Universal\DevicePath\Dxe\DevicePath.c, DevicepathFromText.c, DevicePathUtilities.c;
EdkModulePkg\Universal\Disk\DiskIo\Dxe\diskIo.c; MdePkg\Library\UefiLib\UefiNotTiano.c)
iii) Change some illegal characters in many files, the problem is mainly connected with people using Chinese Input method to input symbols such as ' " - ?, etc. Multiple files are influenced.
