If a consensus expires while we are waiting for certificates to download,
stop waiting for certificates.
If we stop waiting for certificates less than a minute after we started
downloading them, do not consider the certificate download failure a
separate failure.
Fixes bug 20533; bugfix on commit e0204f21 in 0.2.0.9-alpha.
Relays do not deliberately launch multiple attempts, so the impact of this
bug should be minimal. This fix also defends against bugs like #20499.
Bugfix on 0.2.8.1-alpha.
(OpenSSL 1.1 makes EVP_CIPHER_CTX opaque, _and_ adds acceleration
for counter mode on more architectures. So it won't work if we try
the older approach, and it might help if we try the newer one.)
Fixes bug 20588.
In our code to write public keys to a string, for some unfathomable
reason since 253f0f160e, we would allocate a memory BIO, then
set the NOCLOSE flag on it, extract its memory buffer, and free it.
Then a little while later we'd free the memory buffer with
BUF_MEM_free().
As of openssl 1.1 this doesn't work any more, since there is now a
BIO_BUF_MEM structure that wraps the BUF_MEM structure. This
BIO_BUF_MEM doesn't get freed in our code.
So, we had a memory leak!
Is this an openssl bug? Maybe. But our code was already pretty
silly. Why mess around with the NOCLOSE flag here when we can just
keep the BIO object around until we don't need the buffer any more?

The impact here isn't too bad. First, the only affected certs that
expire after 32-bit signed time overflows in Y2038. Second, it could
only make it seem that a non-expired cert is expired: it could never
make it seem that an expired cert was still live.
Fixes bug 20027; bugfix on 0.2.7.2-alpha.
ome policies are default-reject, some default-accept. But
policy_is_reject_star() assumed they were all default_reject. Fix
that!
Also, document that policy_is_reject_star() treats a NULL policy as
empty. This allows us to simplify the checks in
parse_reachable_addresses() by quite a bit.

(Also, refactor the code to create a hidden service directory into a
separate funcion, so we don't have to duplicate it.)
Fixes bug 20484; bugfix on 0.2.9.3-alpha.
This simplifies the function: if we have an ntor key, use ntor/EXTEND2,
otherwise, use TAP/EXTEND.
