1. In AsmFuncs.asm, DebugSupport, Vect2Desc() function will use hardcode CS to fill the IDT. 20h for Ia32.If the system CS is changed by CPU driver, this driver can not work. System maybe crash.
2. In EBC, RegisterExceptionCallback() can not restore the environment and I add some enhancements.
3. In Image.c, CoreLoadImageCommon never return EFI_SECURITY_VIOLATION when SecurityStatus == EFI_SECURITY_VIOLATION.
4. In Variable.c, 1. There're additional unnecessary loop. All blocks will be gone through even if all the data has been written. We should check the "CurrWriteSize" to see if there's no more data to write, and stop the for loop immediately. 2 "if.else." can be merged to save lines of code.
5. in FvbServices,c, Checksum calculation error.
