<li>On Windows, added a fallback implementation for querying file attributes in case if the file cannot be opened with <code>ERROR_ACCESS_DENIED</code> error. This may allow <code>status</code> and <code>symlink_status</code> to succeed for system files and directories that are not reparse points or symlinks.

<li>On Windows, added a workaround for FAT/exFAT filesystems that produce <code>ERROR_INVALID_PARAMETER</code> when querying file attributes. This affected <code>status</code> and <code>symlink_status</code>, which reported that files do not exist, and directory iterators, which failed to construct, as well as other dependent operations.
