/**
* get hop distance of one GeneralName from another in links where
* the names need not have an ancestor/descendant relationship.
* For example, the hop distance from ou=D,ou=C,o=B,c=US to
* ou=F,ou=E,ou=C,o=B,c=US is 3: D->C, C->E, E->F. The hop distance
* from ou=C,o=B,c=US to ou=D,ou=C,o=B,c=US is -1: C->D
*
* @param base GeneralName
* @param test GeneralName to be tested against base
* @param incomparable the value to return if the names are
* incomparable
* @return distance of test name from base measured in hops in the
* namespace hierarchy, where 0 means exact match. Result
* is positive if path is some number of up hops followed by
* some number of down hops; result is negative if path is
* some number of down hops.
