Reid Kleckner 75cbf6dc5c Re-land "Optimize path::remove_dots"
This reverts commit fb5fd74685e728b1d5e68d33e9842bcd734b98e6.
Re-instates commit 53913a65b408ade2956061b4c0aaed6bba907403

The fix is to trim off trailing separators, as in `/foo/bar/` and
produce `/foo/bar`. VFS tests rely on this. I added unit tests for
remove_dots.
