- npapi.h: Correct definitions of function pointer prototypes.

- ntifs.h & cmdata.h : Don't use array size of 0. Fixes C4200.
- wdm.h: Correct definition of 64-bit SLIST_HEADER. Add explicit casts to avoid /W4 warnings in RtlEnlargedUnsignedDivide.
- winddk.h: Add MSVC intrinsic __readfsbyte for KeGetCurrentProcessorNumber. Misc fixes.
- Fix various msvc issues in cmd, setupapi, usetup, win32csr, winlogon, msafd, ws2_32 and ext2lib, most notably:
  - cmd & doskey: Don't use fishy gcc extension to allocate variable-sized arrays from the stack. Use the heap instead.
- Disable warning C4733 for mingw_main too (was only done for mingw_wmain previously).
- advapi32: Pass the correct handles to TRACE -- spotted by MSVC.
- Set the specified register in ecx in MSVC versions of Ke386Wrmsr and Ke386Rdmsr instead of reading from/writing to a random MSR. Yay /W4.
