The rest of the code was only including event.h so that it could see
EV_READ and EV_WRITE, which we were using as part of the
connection_watch_events interface for no very good reason.

This has been some pretty ugly and voodoo-laden code.  I've tried to
clean it up a bit, but more work probably remains.

This patch adds a new compat_libevent.[ch] set of files, and moves our
Libevent compatibility and utilitity functions there.  We build them
into a separate .a so that nothing else in src/commmon depends on
Libevent (partially fixing bug 507).

Also, do not use our own built-in evdns copy when we have Libevent
2.0, whose evdns is finally good enough (thus fixing Bug 920).

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).

Supporting the old formats made our code complex; running without them
has been discouraged since 0.2.1.x.

Specifically if you send SIGUSR1, it will add two lines to the log file:
May 22 07:41:59.576 [notice] Our DNS cache has 3364 entries.
May 22 07:41:59.576 [notice] Our DNS cache size is approximately 1022656
bytes.

[tweaked a bit by nickm]

This way we do not need to rebuild util.c and/or config.c whenever
any unrelated source file in src/common or src/or has changed.

bytes (aka 20KB/s), to match our documentation. Also update
directory authorities so they always assign the Fast flag to relays
with 20KB/s of capacity. Now people running relays won't suddenly
find themselves not seeing any use, if the network gets faster
on average.

they got sent.

The directory authorities were refusing v3 consensus votes from
other authorities, since the votes are now 504K. Fixes bug 959;
bugfix on 0.0.2pre17 (where we raised it from 50K to 500K ;).

It turns out that we weren't updating the _ExcludeExitNodesUnion set's
country numbers when we reloaded (or first loaded!) the IP-to-country
file.  Spotted by Lark.  Bugfix on 0.2.1.6-alpha.

Make dirserv_get_routerdesc_fingerprints() treat extrainfos with send_unencrypted==0 correctly.  Irrelevant, since we will soon never send them at all.

discard it rather than trying to use it. In theory it could
be useful because it lists alternate directory mirrors, but in
practice it just means we spend many minutes trying directory
mirrors that are long gone from the network. Helps bug 887 a bit;
bugfix on 0.2.0.x.

The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed.  They were not actually useful for
telling the version of Tor files in the wild.

More compilation tweaks on Android: fix two clear errors in our code that apparently the compiler cares about there.

Use a consistent naming standard for header file guard macros, taking care not to collide with any system headers.  This tripped us up on Android.

Specifically, split compare_tor_addr_to_addr_policy() from a loop with a bunch
of complicated ifs inside into some ifs, each with a simple loop.  Rearrange
router_find_exact_exit_enclave() to run a little faster.  Bizarrely,
router_policy_rejects_all() shows up on oprofile, so precalculate it per
routerinfo.
