router: eliminate tiny router_build_fresh_descriptor() static functions

Browse Source 
Remove some tiny static functions called by router_build_fresh_descriptor(),
and move their code into more relevant functions.

Then, give router_update_{router,extra}info_descriptor_body identical layouts.

Preparation for testing 29017 and 20918.
