Windows: AFSRedirLib AFSIgnoreReparsePointToFile

AFSIgnoreReparsePointToFile() is a helper routine that uses the
global reparse point policy to decide whether or not a reparse point
whose target is a file should be reported to applications as a file.
When per-AuthGroup or per-Process policy is supported, this function
should be modified.
