Spec conformance issue: The code didn't force the network-status-version
token to be the first token in a v3 vote or consensus.
Problem discovered by Parakeep.
We need to use evdns_add_server_port_with_base() when configuring
our DNS listener, because libevent segfaults otherwise. Add a macro
in compat_libevent.h to pick the correct implementation depending
on the libevent version.

This time, set the SSL3_FLAGS_ALLOW_UNSAFE_RENEGOTIATION flag on every
version before OpenSSL 0.9.8l. I can confirm that the option value (0x0010)
wasn't reused until OpenSSL 1.0.0beta3.
The src and dest of a memcpy() call aren't supposed to overlap,
but we were sometimes calling tor_addr_copy() as a no-op.
Also, tor_addr_assign was a redundant copy of tor_addr_copy(); this patch
removes it.
We implemented ratelimiting for warnings going into the logfile, but didn't
rate-limit controller events. Now both log warnings and controller events
are rate-limited.
Tor has tor_lookup_hostname(), which prefers ipv4 addresses automatically.
Bug 1244 occured because gethostbyname() returned an ipv6 address, which
Tor cannot handle currently. Fixes bug 1244; bugfix on 0.0.2pre25.
Reported by Mike Mestnik.
The problem was that we didn't allocate enough memory on 32-bit
platforms with 64-bit time_t. The memory leak occured every time
we fetched a hidden service descriptor we've fetched before.
When calculating the is_exit flag for a routerinfo_t, we don't need
to call exit_policy_is_general_exit() if router_exit_policy_rejects_all()
tells us it definitely is an exit. This check is much cheaper than
running exit_policy_is_general_exit().
exit_policy_is_general_exit() assumed that there are no redundancies
in the passed policy, in the sense that we actively combine entries
in the policy to really get rid of any redundancy. Since we cannot
do that without massively rewriting the policy lines the relay
operators set, fix exit_policy_is_general_exit().
Fixes bug 1238, discovered by Martin Kowalczyk.
In brief: you mustn't use the SSL3_FLAG solution with anything but 0.9.8l,
and you mustn't use the SSL_OP solution with anything before 0.9.8m, and
you get in _real_ trouble if you try to set the flag in 1.0.0beta, since
they use it for something different.

We need to do this because Apple doesn't update its dev-tools headers
when it updates its libraries in a security patch. On the bright
side, this might get us out of shipping a statically linked OpenSSL on
OSX.
May fix bug 1225.
