93866bec77 [builds/windows] Revert back to CreateFileA only. 
Calling `CreateFileW` without making sure that the patname is really
`wchar_t` is a bad idea and can lead to unpredictable overreads. For
Windows CE, we impelemnt the missing API.

Fixes #1098 and !76 again.

* builds/windows/ftsystem.c (FT_Stream_Open): Call `CreateFileA`.
[_WIN32_WCE] (CreateFileA, FileSizeEx): Implement missing interfaces.

0b429b609c [builds/windows] Try both wide and narrow CreateFile 
Windows handles wchar_t* UTF-16 and char* ANSI (presently UTF-8)
filenames using alternative -A and -W API. We'll try them both
when opening a file. This means that you should not worry about
about conversions.

Fixes #1098 and !76.

* builds/windows/ftsystem.c (FT_Stream_Open): Call alternative
`CreateFile` in the case of failure.

b6c11d494e [smooth] Reduce shift in multiply-shift optimization. 
* src/smooth/ftgrays.c (FT_UDIVPREP, FT_UDIV): Reduce shift.

Smaller shifts that keep the division operands of FT_UDIVPREP within
32 bits result in slightly faster divisions, which is noticeable in
the overall performance.  The loss of precision is tolerable until the
divisors (the components dx and dy) approach 32 - PIXEL_BITS. With
PIXEL_BITS = 8, this corresponds to 65,000 pixels or the bitmap size
that we refuse to render anyway.
