Resolved nontrivial conflict around rewrite_x_address_for_bridge and
learned_bridge_descriptor. Now, since leanred_bridge_descriptor works
on nodes, we must make sure that rewrite_node_address_for_bridge also
works on nodes.

Name the magic value "10" rather than re-deriving it.
Comment more.
Use the pattern that works for periodic timers, not the pattern that
doesn't work. ;)
It is important to verify the uptime claim of a relay instead of just
trusting it, otherwise it becomes too easy to blackhole a specific
hidden service. rephist already has data available that we can use here.
Bugfix on 0.2.0.10-alpha.
The calculation of when to send the logmessage was correct, but we
didn't give the correct number of relays required: We want more than
half of all authorities we know about. Fixes bug 2663.
This fixes a remotely triggerable assert on directory authorities, who
don't handle descriptors with ipv6 contents well yet. We will want to
revert this once we're ready to handle ipv6.
Issue raised by lorth on #tor, who wasn't able to use Tor anymore.
Analyzed with help from Christian Fromme. Fix suggested by arma. Bugfix
on 0.2.1.3-alpha.
We want to use the discard port correctly, so a htons() was missing.
Also we need to set it correctly depending on address family.

SSL_*_app_data uses ex_data index 0, which will be the first one allocated
by SSL_get_ex_new_index. Thus, if we ever started using the ex_data feature
for some other purpose, or a library linked to Tor ever started using
OpenSSL's ex_data feature, Tor would break in spectacular and mysterious
ways. Using the SSL_*_ex_data functions directly now may save us from
that particular form of breakage in the future.
But I would not be surprised if using OpenSSL's ex_data functions at all
(directly or not) comes back to bite us on our backends quite hard. The
specified behaviour of dup_func in the man page is stupid, and
crypto/ex_data.c is a horrific mess.
This should fix a bug that special ran into, where if your state file
didn't record period maxima, it would never decide that it had
successfully parsed itself unless you got lucky with your
uninitialized-variable values.
This patch also tries to improve error messags in the case where a
maximum value legitimately doesn't parse.
In private networks, the defaults for some options are changed. This
means that in options_validate(), where we're testing that the defaults
are what we think they are, we fail. Use a workaround by setting a
hidden configuration option _UsingTestingTorNetwork when we have altered
the configuration this way, so that options_validate() can do the right
thing.
Fixes bug 2250, bugfix on 0.2.1.2-alpha (the version introducing private
network options).
Changed received_netinfo_from_trusted_dir into a
tristate in order to keep track of whether we have
already tried contacting a trusted dir. So we don't
send multiple requests if we get a bunch of skews.
The underlying fix is to stop indicating requests "ns" consensuses by
putting NULL in their requested_resource field: we already had a
specialized meaning for requested_resource==NULL, which was (more or
less) "Treat a failure here as a network failure, since it's too early
to possibly be a resource or directory failure." Overloading the two
meant that very early microdesc consensus download failures would get
treated as ns consensus download failures, so the failure count there
would get incremented, but the microdesc download would get retried
immediately in an infinite loop.
Fix for bug2381. Diagnosed by mobmix.
Sets:
* Documentation
* Logging domain
* Configuration option
* Scheduled event
* Makefile
It also creates status.c and the log_heartbeat() function.
All code was written by Sebastian Hahn. Commit message was
written by me (George Kadianakis).
Our regular DH parameters that we use for circuit and rendezvous
crypto are unchanged. This is yet another small step on the path of
protocol fingerprinting resistance.
(Backport from 0.2.2's 5ed73e3807)
Patch our implementation of tor_lockfile_lock() to handle this case
correctly. Also add a note that blocking behaviour differs from windows
to *nix. Fixes bug 2504, issue pointed out by mobmix.
