Comment(by ln5):

 onion_extend_cpath() (calling extend_info_from_node()) determines
 whether the "preferred" (i.e. IPv4 or IPv6) or the "primary"
 (i.e. IPv4) address is to be used.

 We need #4620 to be fixed in order to make it possible to pick the
 preferred OR port based on routerstatus + microdescriptor. This is
 important both for clients using microdescriptors and doing ordinary
 three-hop circuits as well as for one-hop BEGIN_DIR circuits (for
 fetching directory info, like server descriptors).
