Remember the valid-until time of the most recent consensus that listed
a router, and (if we are a cache) never delete the routerdesc until
that conensus is expired. This is way easier than retaining multiple
consensuses. (Of course, the info isn't retained across restarts,
but that only affects a few caches at a time.)

When a networkstatus consensus download fails, do not wait 60 seconds to decide whether to retry. (Also, log the time at which we'll try to replace the current networkstatus.)

oprofile was telling me that a fair bit of our time in openssl was spent in base64_decode, so replace base64_decode with an all-at-once fairly optimized implementation. For decoding keys and digests, it seems 3-3.5x faster than calling out to openssl. (Yes, I wrote it from scratch.)
svn:r12002
Make unverified-consensus get removed when it is accepted or rejected. Make a new get_datadir_fname*() set of functions to eliminate the common code of "get the options, get the datadir, append some stuff".
svn:r12000
Implement v3 networkstatus client code. Remove v2 networkstatus client code, except as needed for caches to fetch and serve v2 networkstatues and the routers they list.
svn:r11957
Make discard_old_votes part of the consensus publishing process, so we conform to spec, and so we avoid a weird bugs where publishing sets the consensus, setting the consensus makes us reschedule, and rescheduling makes us delay vote-discarding.
svn:r11944
when we find our DirPort to be reachable but won't actually publish
it. Extra descriptors without any real changes are dropped by the
authorities, and can screw up our "publish every 18 hours" schedule.

Fix bug 451. This was a nasty bug, so let's fix it twice: first, by banning recursive calls to connection_handle_write from connection_flushed_some; and second, by not calling connection_finished_flushing() on a closed connection. Backport candidate.
svn:r11882
Fix a bunch of XXX020s: treat some 403s as INFO severity; remove some dead code; share the retry path for consensus routerdescs that are also listed in the v2 networkstatus; check even more aspects of votes when parsing them.
svn:r11871
Fix the implementation of if-modified-since for certificates so that it applies to all types of certificate requests. Note that the kind of consensus that matters already has a working if-modified-since.
svn:r11852
Fix some memory leaks when serving v3 networkstatus documents and v3 certs. Generate 503 correctly when serving v3 networkstatus documents and v3 certs.
svn:r11850
Retry consensus and certificate downloads properly. Do not fail when there are no certificates to download. Do not download certificates we already have when retrying.
svn:r11841
Save weighted-fractional-uptime to disk as well as MTBF. Bump the version on rouer-stability: downgrading to versions earlier than this one will lose your WFU data.
svn:r11835
Fix the bug that was making moria1 set valid-after wrong in its votes: we were looking at the preferred timing when we should have been looking at the consensus timing.
svn:r11818
