Ffprobe fails to open images with international characters in the file name

Ffprobe on Windows fails to open files with international characters in the file name when pattern_type is used.
How to reproduce:

% ffprobe pattern_type=sequence "файл%0.jpg"

Tested on git-master and 2.8.2 - 2.8.6 on Windows
In case sequence pattern is in use, all of the versions fail.

Cause (libavformat):
If pattern_type is set, img2dec.c/find_image_range() is called. Further, this invokes avio.c/avio_check() followed by file.c/file_check(). File_check() calls C library function stat(), and the last one fails when provided with a const char *path containing international characters in UTF-8.

Possible solution:
Use utf8towchar() similar to file_open.c/win32_open() to convert the string to a wide char string, and use _wstat() instead of stat().
