Apparently all the stuff that does a linear scan over all the DNS
cache entries can get really expensive when your DNS cache is very
large.  It's hard to say how much this will help performance, since
gprof doesn't count time spent in OpenSSL or zlib, but I'd guess 10%.

Also, this patch removes calls to assert_connection_ok() from inside
the read and write callbacks, which are similarly unneeded, and a
little costlier than I'm happy with.

This is probably worth backporting to 0.2.0.

Provide a useful warning when launch_circuit tries to make us use a
node we don't want to use.  Just give an info message when this is a
normal and okay situation.  Fix for logging issues in bug 984.

Include a changelog, and don't try to compare strings with !=.

This patch adds a function to determine whether we're in the main
thread, and changes control_event_logmsg() to return immediately if
we're in a subthread.  This is necessary because otherwise we will
call connection_write_to_buf, which modifies non-locked data
structures.

Bugfix on 0.2.0.x; fix for at least one of the things currently
called "bug 977".

(Simplify "if (cond) return 1; return 0;" to "return cond;", and don't
give a warning when we start with accounting on but dirport off.)

Tas (thanks!) noticed that when *ListenAddress is set, Tor would
still warn on startup when *Port is low and hibernation is active.
The patch parses all the *ListenAddress lines, and checks the
ports. Bugfix on 0.2.1.15-rc

These were made undone by a merge.

This proposal tries to do what 134 tried to do, but more securely and
with less whiz-bang NP-hard computation.  Peter had the basic idea.

With the last fix of task 932 (5f03d6c5), client requests are only added to
the history when they happen after the start of the current history. This
conflicts with the unit tests that insert current requests first (defining
the start of the client request history) followed by requests in the past.
The fix is to insert requests in chronological order in the unit tests.

Change the way how directories that are configured with --enable-geoip-stats write geoip stats to disk.

- Write geoip stats to disk every 24 hours, not every hour.
- Remove configuration options and define reasonable defaults.
- Clear history of client requests every 24 hours (which wasn't done at
  all before).

Ignore connections two hours after switching from bridge to relay or back.

Use two bitfields for last_seen and action in clientmap_entry_t rather
than having both share a 32-bit. Also, documentation fixes.
