From d8b6ff2dad1de2d98a407ecf67a34fe12e67d494 Mon Sep 17 00:00:00 2001
From: Nathan Harmata <nharmata@google.com>
Date: Tue, 20 Oct 2015 21:54:34 +0000
Subject: Introduce Path#isSpecialFile, FileSystem#isSpecialFile, and
 FileStatus#isSpecialFile to help disambiguate between a regular file and a
 special file, since the file size of a special file cannot be trusted.
