When we tried to use the deprecated non-threadsafe evdns
interfaces in Libevent 2 without using the also-deprecated
event_init() interface, Libevent 2 would sensibly crash, since it
has no guess where to find the Libevent library.
Here we use the evdns_base_*() functions instead if they're
present, and fake them if they aren't.

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 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).

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.

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.

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.

(The unfixed ones are being downgraded to regular XXXs mainly on the rationale that they don't seem to be exploding Tor, and they were apparently not showstoppers for 0.2.0.x-final.)

Initial conversion of uint32_t addr to tor_addr_t addr in connection_t and related types. Most of the Tor wire formats using these new types are in, but the code to generate and use it is not. This is a big patch. Let me know what it breaks for you.

Answer one xxx020 item; move 7 other ones to a new "XXX020rc" category: they should get fixed before we cut a release candidate. arma: please review these to see whether you have fixes/answers for any. Please check out the other 14 XXX020s to see if any look critical for the release candidate.
