Comment (by fergus):

 The {{{routerset_contains_*}}} functions are all just wrappers around
 {{{routerset_contains}}} that pull the information from different data
 structures. {{{routerset_contains}}} itself isn't in the header file or
 called by anything else.

 An issue I have just noticed is that the {{{extend_info_t}}} struct only
 has the address being connected to, but it needs to be checked against
 ExcludeNodes, which could cause it to be used if only the other address is
 excluded. I'm not really sure what to do about that.
