[PATCH v3 0/1] MR5236: ntdll: Implement NtdllDefWindowProc_A().

[Aida Jonikienė]

I've tried implementing this before but importing user32 from ntdll isn't a reliable
thing (so I recently rewrote it using the ntdll equivalents of LoadLibrary() and GetProcAddress())

Note: This is a weird way to implement this function (Windows implements this
in ntdll instead) but that would probably require a user32/ntdll rewrite (so this
is the next best tning to get the application working)
