[libvirt] [PATCH 2/2] Prohibit Windows special chars in filenames

[Matthias Bolte]

Using any of these chars [:*?"<>|] in a filename is forbidden on
Windows and breaks git operations on Windows as git is not able
to create those files/directories on clone or pull.

Because some of them can be used in UNIX filenames they tend to
creep into filenames, especially : in PCI/SCSI device names that
are used as filenames in test cases.
