6700e528be Fix some precision-related asserts in unit tests.
Mostly by storing the timeout as milliseconds and not seconds
internally.

when the network changes.

0352d43917 Move circuitbuildtimeout config check.
We want it to be under our control so it doesn't mess
up initialization. This is likely the cause for
the bug the previous assert-adding commit (09a75ad) was
trying to address.

6eba08e22f Use our variable directly for timeout.
Using CircuitBuildTimeout is prone to issues with SIGHUP, etc.
Also, shuffle the circuit build times array after loading it
in so that newer measurements don't replace chunks of
similarly timed measurements.

95735e5478 Fix the math.h log() conflict.
It was compiling, but causing segfaults.

Also, adjust when the timer starts for new test circs
and save state every 25 circuits.

c43859c5c1 Read "circwindow=x" from the consensus and use it
Tor now reads the "circwindow" parameter out of the consensus,
and uses that value for its circuit package window rather than the
default of 1000 cells. Begins the implementation of proposal 168.

381766ce4b Implement proposal 167: Authorities vote on network parameters.
This code adds a new field to vote on: "params".  It consists of a list of
sorted key=int pairs.  The output is computed as the median of all the
integers for any key on which anybody voted.

Improved with input from Roger.

daa0326aaa 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.

3e45445104 Changing MaxAdvertisedBW may not need a republish
Relays no longer publish a new server descriptor if they change
their MaxAdvertisedBandwidth config option but it doesn't end up
changing their advertised bandwidth numbers. Bugfix on 0.2.0.28-rc;
fixes bug 1026. Patch from Sebastian.

2b63fa40e8 three hacks to workaround bug 1038
The problem is that clients and hidden services are receiving
relay_early cells, and they tear down the circuit.

Hack #1 is for rendezvous points to rewrite relay_early cells to
relay cells. That way there are never any incoming relay_early cells.

Hack #2 is for clients and hidden services to never send a relay_early
cell on an established rendezvous circuit. That works around rendezvous
points that haven't upgraded yet.

Hack #3 is for clients and hidden services to not tear down the circuit
when they receive an inbound relay_early cell. We already refuse extend
cells at clients.

8c496d1660 Some tweaks to statistics.
Changes to directory request statistics:

- Rename GEOIP statistics to DIRREQ statistics, because they now include
  more than only GeoIP-based statistics, whereas other statistics are
  GeoIP-dependent, too.
- Rename output file from geoip-stats to dirreq-stats.
- Add new config option DirReqStatistics that is required to measure
  directory request statistics.
- Clean up ChangeLog.

Also ensure that entry guards statistics have access to a local GeoIP
database.

e7576f92de Add support for a new option: FetchDirInfoExtraEarly
This new option will allow clients to download the newest fresh consensus
much sooner than they normally would do so, even if they previously set
FetchDirInfoEarly. This includes a proper ChangeLog entry and an updated man
page.
