This also adds comprehensive tests for utimens on regular files, directories (RHBZ#761451), named pipes (RHBZ#761460), symbolic links, block and char devices. Note that there is a small change in the (previously undefined) semantics of this call: It now sets the time on a symbolic link itself, not on what the symbolic link points to.
