Don't use the getaddrinfo sandbox cache from tor-resolve

Fixes bug 13295; bugfix on 0.2.5.3-alpha.

The alternative here is to call crypto_global_init() from tor-resolve,
but let's avoid linking openssl into tor-resolve for as long as we
can.
Merge branch 'bug13295_v2_025' into maint-0.2.5
Run correctly on OpenBSD systems without SSL_METHOD.get_cipher_by_char

Also, make sure we will compile correctly on systems where they
finally rip it out.

Disable SSLv3 unconditionally. Closes ticket 13426.

The POODLE attack doesn't affect Tor, but there's no reason to tempt
fate: SSLv3 isn't going to get any better.
