[ros-kernel] Some recent header changes

[art yerkes]

Some recent checkins are breaking the build for me.  The main one is
a change to tchar.h that does include_next <tchar.h>.  I don't have
another one, so this fails.

I'm missing the prototypes for NtGdiGetFontData, and _tsplitpath as
well.  I fixed my tree temporarily, but do I need new versions of
the w32api headers or anything like that?
