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.

Routine Description:
|

Creates a copy of the current device path instance and returns a pointer to the next device path instance.
|

|

Arguments:
|
||||
DevicePathInstance - On input, this holds the pointer to the current device path
|
||||
instance. On output, this holds the pointer to the next
|
||||
device path instance or NULL if there are no more device
|

path instances in the device path.
|
||||
DevicePathInstanceSize - On output, this holds the size of the device path instance,
|
||||
in bytes or zero, if DevicePathInstance is zero.
|

|
||||
Returns:
|
||||
Pointer - A pointer to the copy of the current device path instance.
