Timo Kreuzer 0182dcd71b [PSDK][REACTOS] Fix definitions and usage of DWLP_MSGRESULT, DWLP_DLGPROC, and DWLP_USER
- Make sure the DWLP_* values are correct on _WIN64
- Don't use the DWL_* constants, they are not portable. Enforce this by removing them entirely from winuser.h
- Make sure Get/SetWindowLong*Ptr* is used and pointers are not truncated to LONG
