dfc6b5c814 file: Move win32 utf8->wchar open wrapper to libavutil
When libavformat was changed to use the new avpriv_open function
in 51eb213d00, this silently bypassed the existing wrapper for
win32. Move the win32 wrapper into libavutil/file.c to make sure
it gets called everywhere (not just in the libavformat case).

This makes sure that non-ascii file names gets opened properly
(where file names internally are stored as utf8, but they get
converted to wchar_t and opened with _wsopen).

15816c8e8b avutil: Include io.h with a separate condition from MapViewOfFile
The existence of MapViewOfFile isn't linked to the existence of
io.h.

Not all versions of windows have MapViewOfFile (in particular,
Windows Phone 8 and the "metro" windows 8 API subset don't),
while they still have io.h (and need it for open/read/close).
