166c2f4d92 Allow enabling or disabling *Statistics while Tor is running.
With this patch we stop scheduling when we should write statistics using a
single timestamp in run_scheduled_events(). Instead, we remember when a
statistics interval starts separately for each statistic type in geoip.c
and rephist.c. Every time run_scheduled_events() tries to write stats to
disk, it learns when it should schedule the next such attempt.

This patch also enables all statistics to be stopped and restarted at a
later time.

This patch comes with a few refactorings, some of which were not easily
doable without the patch.

d38268a8c7 Remove v0 hidden service statistics code.
The HSAuthorityRecordStats option was used to track statistics of overall
hidden service usage on the version 0 hidden service authorities. With the
version 2 hidden service directories being deployed and version 0
descriptors being phased out, these statistics are not as useful anymore.

Goodbye, you fine piece of software; my first major code contribution to
Tor.

3807db001d *_free functions now accept NULL
Some *_free functions threw asserts when passed NULL. Now all of them
accept NULL as input and perform no action when called that way.

This gains us consistence for our free functions, and allows some
code simplifications where an explicit null check is no longer necessary.

16fbb2f745 Minor fix to buffer stats.
Do not segfault when writing buffer stats when we haven't observed a
single circuit to report about.  This is a minor bug that would only show
up in testing environments with no traffic and with reduced stats
intervals.

457bebe01a Fix a couple of smaller issues with gathering statistics.
- Avoid memmoving 0 bytes which might lead to compiler warnings.

- Don't require relays to be entry node AND bridge at the same to time to
  record clients.

- Fix a memory leak when writing dirreq-stats.

- Don't say in the stats files that measurement intervals are twice as long
  as they really are.

- Reduce minimum observation time for requests to 12 hours, or we might
  never record usage.

- Clear exit stats correctly after writing them, or we accumulate old stats
  over time.

- Reset interval start for buffer stats, too.

8c29b7920a 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.

7fb206e554 Tweak exit port statistics a bit.
Introduce a threshold of 0.01% of bytes that must be read and written per
port in order to be included in the statistics. Otherwise we cannot include
these statistics in extra-info documents, because they are too big.

Change the labels "-written" and "-read" so that the meanings are as
intended.

e7bc189f7c the third piece of bug 969 fixing
when we write out our stability info, detect relays that have slipped
through the cracks. log about them and correct the problem.

if we continue to see a lot of these over time, it means there's another
spot where relays fall out of the routerlist without being marked as
unreachable.
