Description

The problem is visible by running TestDFSShell#testFilePermissions. The test fails on trying to set sticky bit. The problem is that branch-trunk-win accidentally merged in a branch-1 change in RawLocalFileSystem#setPermission to call FileUtil#setPermission, which sets permissions using Java File API. There is no way to set sticky bit through this API. We need to switch back to the trunk implementation of RawLocalFileSystem#setPermission, which uses either native code or a shell call to external chmod.
