This is the simplest possible workaround: make it safe to call
circuit_cell_queue_clear() on a non-attached circuit, and make it
safe-but-a-LD_BUG-warning to call update_circuit_on_cmux() on a
non-attached circuit.

Apparently some compilers like to eliminate memset() operations on
data that's about to go out-of-scope. I've gone with the safest
possible replacement, which might be a bit slow. I don't think this
is critical path in any way that will affect performance, but if it
is, we can work on that in 0.2.4.
Fixes bug 7352.
Instead of warning about low ports that are advertised, we should have
been warning about low ports that we're listening on. Bug 7285, fix
on 0.2.3.9-alpha.
We still want to build on compilers w/o c99 support, such as
(notoriously, shamefully) MSVC.
So I'm commenting out the designated initializers in
circuitmux_ewma.c. The alternative would have been to use some kind
of macros to use designated initializers only when they're
supported, but that's error-prone, and can lead to code having
different meanings under different compilers.
Bug 7286; fix on 0.2.4.4-alpha; spotted by Gisle Vanem.
When configuring tor without upnp support, ie ./configure --disable-upnp,
tor-fw-helper fails to link with undefined references to `ceil' and
`log'. This if fixed by linking to libm.

If we completed the handshake for the v2 link protocol but wound up
negotiating the wong protocol version, we'd become so confused about
what part of the handshake we were in that we'd promptly die with an
assertion.
This is a fix for CVE-2012-2250; it's a bugfix on 0.2.3.6-alpha.
All servers running that version or later should really upgrade.
Bug and fix from "some guy from France." I tweaked his code slightly
to make it log the IP of the offending node, and to forward-port it to
0.2.4.

The implementation we added has a tendency to crash with lists of 0 or
one element. That can happen if we get a consensus vote, v2
consensus, consensus, or geoip file with 0 or 1 element. There's a
DOS opportunity there that authorities could exploit against one
another, and which an evil v2 authority could exploit against anything
downloading v2 directory information..
This fix is minimalistic: It just adds a special-case for 0- and
1-element lists. For 0.2.4 (the current alpha series) we'll want a
better patch.
This is bug 7191; it's a fix on 0.2.0.10-alpha.
