Only send netinfo clock_skew to controller if an authority told us so
We were triggering a CLOCK_SKEW controller status event whenever
we connect via the v2 connection protocol to any relay that has
a wrong clock. Instead, we should only inform the controller when
it's a trusted authority that claims our clock is wrong. Bugfix
on 0.2.0.20-rc; starts to fix bug 1074. Reported by SwissTorExit.

Add some fixes after discussion with Nick.
- 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.

Add the first 8 bytes of the git commit digest to our versions.
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.

Notice v3 cert parsing failures
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".

Fix a rare infinite-recursion bug when shutting down.
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 SHA256 implementation for platforms that lack it.
(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.

Fix possible segmentation fault on directory authorities.
The more verbose logs that were added in ee58153 also include a string
that might not have been initialized. This can lead to segfaults, e.g.,
when setting up private Tor networks. Initialize this string with NULL.

Send sendmes when we're down 100 cells, not 101.
Send circuit or stream sendme cells when our window has decreased

Add a new tor_strtok_r for platforms that don't have one, plus tests.
I don't think we actually use (or plan to use) strtok_r in a reentrant

whether we're doing it.
