0d68da23 removed support for Version 0,
but didn't fix the manpage.

Resolved conflict in:

- Refactor geoip.c by moving duplicate code into rotate_request_period().
- Don't leak memory when cleaning up cell queues.
- Make sure that exit_(streams|bytes_(read|written)) are initialized in all
  places accessing these arrays.
- Read only the last block from *stats files and ensure that its timestamp
  is not more than 25 hours in the past and not more than 1 hour in the
  future.
- Stop truncating the last character when reading *stats files.

The only thing that's left now is to avoid reading whole *stats files into
memory.

This patch avoids a bunch of allocations, and avoids using unallocated
memory.

Note that unlike subversion revision numbers, it isn't meaningful to
compare these for anything but equality.  We define a sort-order anyway,
in case one of these accidentally slips into a recommended-versions
list.

If any the v3 certs we download are unparseable, we should actually
notice the failure so we don't retry indefinitely. Bugfix on 0.2.0.x;
reported by "rotator".

Fixes bug in f57883a3.

Once we had called log_free_all(), anything that tried to log a
message (like a failed tor_assert()) would fail like this:

   1. The logging call eventually invokes the _log() function.
   2. _log() calls tor_mutex_lock(log_mutex).
   3. tor_mutex_lock(m) calls tor_assert(m).
   4. Since we freed the log_mutex, tor_assert() fails, and tries to
      log its failure.
   5. GOTO 1.

Now we allocate the mutex statically, and never destroy it on
shutdown.

Bugfix on 0.2.0.16-alpha, which introduced the log mutex.

Add a new function to derive the declared method list from
consensus_method_is_supported().

(This would be everywhere running OpenSSL 0.9.7x and earlier, including
all current Macintosh users.)

The code is based on Tom St Denis's LibTomCrypt implementation,
modified to be way less general and use Tor's existing facilities.  I
picked this one because it was pretty fast and pretty free, and
because Python uses it too.

This adds an openssl 0.9.8 dependency.  Let's see if anybody cares.
