To work out what is happening in a replication graph, it is sometimes helpful to use visualisations. We introduce a samba-tool subcommand to write Graphviz dot output and generate text-based heatmaps of the distance in hops between DCs. There are two subcommands, two graphical modes, and (roughly) two modes of operation with respect to the location of authority. `samba-tool visualize ntdsconn` looks at NTDS Connections. `samba-tool visualize reps` looks at repsTo and repsFrom objects. In '--distance' mode (default), the distances between DCs are shown in a matrix in the terminal. With '--color=yes', this is depicted as a heatmap. With '--utf8' it is a lttle prettier. In '--dot' mode, Graphviz dot output is generated. When viewed using dot or xdot, this shows the network as a graph with DCs as vertices and connections edges. Certain types of degenerate edges are shown in different colours or line-styles. Normally samba-tool talks to one database; with the '-r' (a.k.a. '--talk-to-remote') option attempts are made to contact all the DCs known to the first database. This is necessary to get sensible results from `samba-tool visualize reps` because the repsFrom/To objects are not replicated, and it can reveal replication issues in other modes.
