You could move foo_name_vals[] to a header file in epan/dissectors,
extend it and then include it in both the dissector and your plugin.
If the normal dissector doesn't come across those extra values you put
in the value string, it will just ignore them. However, there is the
potential of issues with not having all of the plug-in's files within
the plug-in directory.
