Avoid unhelpful warnings about UDP buffer sizes.
Don't log a warning if we never explicitly configured the
SO_RCVBUF/SO_SNDBUF sizes, and don't warn if the system allocates a
larger buffer than the one requested, as at least on Linux, it will
always double the requested size unless you hit the maximum. With this
change, we only warn when we explicitly request a buffer size and the
system allocated a smaller one.

Don't call OPENSSL_cleanup().
Some versions of LibreSSL don't have this function, even if they support
the rest of the OpenSSL 1.1 API. It also doesn't seem to affect the
output of Valgrind, so it looks like it's not necessary at all.

Call ENGINE_load_builtin_engines().
As suggested by Rosen Penev, use ENGINE_load_builtin_engines() to ensure
the AFALG engines get loaded as well. We apparently also don't need to
call OPENSSL_init_crypto() ourself.

Make tinc --batch --force join enable the tinc-up script.
The expected behavior of --batch --force is that all parameters in the
invitation are accepted, whether unsafe or not. Unsafe variables were
already accepted with --force in commit
061362d2f, this commit ensures
the generated tinc-up script is enabled as well.

Require OpenSSL 1.1.0 or later.
This gets rid of some backwards compatibility code, and avoids calling
deprecated OpenSSL functions.

Avoid trying to send an ANS_KEY request to unreachable nodes.
We could have a REQ_KEY coming from a node that is not reachable; either
because DEL_EDGEs have overtaken the REQ_KEY, or perhaps if TunnelServer
is used and some nodes have a different view of reachability.
This might fix GitHub issue #247.

Slightly better RNG seed for tincctl.
This prevents the Port from being the same when initializing multiple
