The real file behind a site path under a site's link policy. With skip
it is safeLocalTarget: no link is read or written through. With
follow-inside-root and follow, each link on the way is followed to its
real path, refused when it leads nowhere, and with follow-inside-root
refused when it leads out of the real local root. Every other folder on
the way must be the very folder its name says, so no Windows short name
stands in for another. lookup and platform are replaceable in tests.
