Add smb3 mount helper

[Steve French]

Yes - we could move common code to a common C file - would be fairly
easy to reduce most of the duplicated code (and can do the diff
between the two mount.cifs.c vs mount.smb3.c)  - goal is also to
behave differently for the two (we don't want to show/display/use
obsolete options in the mount.smb3.c flavor of the mount helper)
