5 years agolavf: Use wchar functions for filenames on windows for mkdir/rmdir/rename/unlink

lavf: Use wchar functions for filenames on windows for mkdir/rmdir/rename/unlink

properly - the normal file handling functions assume path names
are in the native codepage, which isn't utf8.

This assumes that the tools outside of lavf don't use the mkdir
definition. (The tools don't do the same reading of command line
parameters as wchar either - they probably won't handle all possible
unicode file parameters properly, but at least work more predictably
if no utf8/wchar conversion is involved.)

be included before winsock2.h, while io.h needs to be included before
the manual defines for lseek functions.
