 We should make router_dump_router_to_string() and
 extrainfo_dump_to_string() deterministic transforms of routerinfo_t and
 extrainfo_t.

 At the moment, these functions access options, internal state, and
 statistics files. If all those accesses occurred in
 router_build_fresh_unsigned_{router,extra}info() then the dump functions
 would be a lot easier to test.
