1. Add the fix for the following Bugs:
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.

+ At a minimum, any blob of data could be represented as a hex string.

+ Arguments:
+ Str - Pointer to the string.
+ HexStringBufferLength - Length in bytes of buffer to hold the hex string. Includes tailing '\0' character.
+ If routine return with EFI_SUCCESS, containing length of hex string buffer.
+ If routine return with EFI_BUFFER_TOO_SMALL, containg length of hex string buffer desired.
+ Buf - Buffer to be converted from.
+ Len - Length in bytes of the buffer to be converted.
+
+ Returns:
+ EFI_SUCCESS: Routine success.
+ EFI_BUFFER_TOO_SMALL: The hex string buffer is too small.
