avutil/file: fix av_file_map file mapping on Windows This makes the behavior of av_file_map() the same on Windows as it is on other platforms. The file is opened as read-only, but the mapping is copy-on-write, allowing the user to write to the memory pages returned by av_file_map(). This commit fixes libavutil\tests\file.c test, which would crash when trying to write to a read-only memory page.
