Log:
- Implement large ansi unicode string support for win32k. I guess some Rtl library
developer should look into adding lib/rtlw32k for Win32k and User32.
- Created DefSetText to processes strings prior to calling NtUserDefSetText.
- Rewrite NtUserDefSetText to support large strings and process them with
RtlLargeStringToUnicodeString.
- On last thing to remove, is the Hook junk in NtUserDefSetText.
