Never vote for an ed key twice.
When generating a vote, and we have two routerinfos with the same ed
key, omit the one published earlier.
This was supposed to have been solved by key pinning, but when I
made key pinning optional, I didn't realize that this would jump up
and bite us. It is part of bug 18318, and the root cause of 17668.
Previously, I had left in some debugging code with /*XXX*/ after it,
which nobody noticed. Live and learn! Next time I will use /*XXX
DO NOT COMMIT*/ or something.
We need to define a new consensus method for this; consensus method
21 shouldn't actually be used.

Fix backtrace compilation on FreeBSD
On FreeBSD backtrace(3) uses size_t instead of int (as glibc does). This
causes integer precision loss errors when we used int to store its
results.
The issue is fixed by using size_t to store the results of backtrace(3).
The manual page of glibc does not mention that backtrace(3) returns
negative values. Therefore, no unsigned integer wrapping occurs when its
result is stored in an unsigned data type.

Use variables instead of substitutions
Using variables removes the ambiguity about when to use variables and
when to use substitutions. Variables always work. Substitutions only
work when Autoconf knows about them which is not always the case.
The variables are also placed between quotes to ensures spaces in the
variables are handled properly.

Fix a compilation warning introduced by clang 3.6
There was a dead check when we made sure that an array member of a
struct was non-NULL. Tor has been doing this check since at least
0.2.3, maybe earlier.

Format IPv6 policies correctly.
Previously we'd suppressed the mask-bits field in the output when
formatting a policy if it was >=32. But that should be a >=128 if
we're talking about IPv6.
Since we didn't put these in descriptors, this bug affects only log
messages and controller outputs.
Fix for bug 16056. The code in question was new in 0.2.0, but the
bug was introduced in 0.2.4 when we started supporting IPv6 exits.
The tor_cert_get_checkable_sig function uses the signing key included in
the certificate (if available) when a separate public key is not given.
When the signature is valid, the tor_cert_checksig function copies the
public key from the checkable structure to the public key field of the
certificate signing key.
In situations where the separate public key is not given but the
certificate includes a signing key, the source and destination pointers
in the copy operation are equal and invoke undefined behavior.
Undefined behaviour is avoided by ensuring both pointers are different.

Fix: use the right list in find_expiring_intro_point()
The wrong list was used when looking up expired intro points in a rend
service object causing what we think could be reachability issues and
triggering a BUG log.

Check for len < 4 in dn_indicates_v3_cert
Without this check, we potentially look up to 3 characters before
the start of a malloc'd segment, which could provoke a crash under
certain (weird afaik) circumstances.

Work around openssl declaring x509_get_not{Before,After} as functions
Now that x509_get_not{Before,After} are functions in OpenSSL 1.1
(not yet releasesd), we need to define a variant that takes a const
pointer to X509 and returns a const pointer to ASN1_time.
Part of 17237. I'm not convinced this is an openssl bug or a tor
bug. It might be just one of those things.
get_interface_address6_list(): Bring back a return code check
... that was removed by 31eb486c46 which first appeared in
0.2.7.3-rc.
If tor is running in a ElectroBSD (or FreeBSD) jail it can't
get any IP addresses that aren't assigned to the jail by
looking at the interfaces and (by design) the
get_interface_address6_via_udp_socket_hack() fallback doesn't
work either.
The missing return code check resulted in tor_addr_is_internal()
complaining about a "non-IP address of type 49", due to reading
uninitialised memory.
