router_set_networkstatus() gets a list of status documents we asked for from
connection_dir_client_reached_eof(). However, as a cache we (sometimes?) just
ask for "all". router_set_networkstatus() would freak out over that, meaning
it would log a warning and drop the status document instead of caching it
as it is supposed to. Now we let router_set_networkstatus() know if the
data comes from an all-request so it can do the right thing.

Change networkstatus dl logic: try to have all networkstatuses live; insist on having all of them live or tried-at-least-once. Also, answer a XXXX comment.

When deciding whether a router is Fast or Guard-worthy, consider
...
his advertised BandwidthRate and not just the BandwidthCapacity.
This is a bug in 0.1.0.x as well, but let's not bother backporting.

Note a vulnerability with our current recommended-version concensus

building.
Make the warnings about invalid and unnamed nodes scale better, and
update the text of the warnings.
Change router_have_minimum_dir_info() to only be happy when it has
enough network-statuses ("more than half") to be willing to actually
build circuits.
Not yet done: when we fail to get a networkstatus that we wanted, and
!router_have_minimum_dir_info(), we should retry it quicker than a whole
minute from now.
