Log:
[Win32k|User32]
- Remove the old send message API and use NtUserMessageCall.
- Send messages do not pass the Ansi bit. This was evident during the hook changes. User32
knows the caller is Ansi and with a Unicode window user32 can make the apropate switch.
Win32k on the other hand, assumes, based on the Unicode window the caller is Unicode. Hook
tests enabled in send message, forces the call to win32k, and the Ansi product is Unicode
data. Using NtUserMessageCall this bit can be passed forward to allow win32k to make the
correct switch going to callback.
