[Libguestfs] [PATCH v2] Allow 9p filesystems to be listed and mounted (RHBZ#714981).

Second version. I have tested these and they work. The earlier version of the patch which modified the mount-vfs call so that the Device parameter became a String would not have worked properly. It would mean that device name translation[1] would not have been done on that parameter any longer. I also considered changing all the mount calls so that they take a string instead of a device name, and then doing device name translation manually (ie. calling RESOLVE_DEVICE conditionally, as is done in do_umount[2]). This would also allow bind mounts, but would also lead to a very complex do_mount_vfs[3] implementation. So this implements a separate API: guestfs_mount_9p, specifically for this purpose of mounting 9p filesystems discovered through guestfs_list_9p. The advantage of having an API is it's simple and specialized, and we can deprecate it later if we find a better way to do it. Please test it, and tell me if it works for you. Rich.
