test suite: use stock OpenSSL config except for tests/tls-protocols.

It's best to use a stock (clean) environment when possible.  We only
need to test TLS protocol version <1.2 for tests/tls-protocols.

test suite: ensure we haven't started speaking IMAP when the SSL/TLS handshake is aborted.

2020-12-13T16:38:07+00:00

(Unless STARTTLS is used to upgrade the connection.)

libinterimap: deprecate SSL_protocols and introduce SSL_protocol_{min,max}.

2020-12-11T18:33:30+00:00

Using the libssl interface simplifies our protocol black/whitelist
greatly; this only allows simple min/max bounds, but holes are arguably
not very useful here.

Using the new settings bumps the required libssl version to 1.1.0.

libinterimap: remove default SSL_protocols value.

2020-12-11T17:32:16+00:00

Namely, use the system default instead of "!SSLv2 !SSLv3 !TLSv1 !TLSv1.1".

As of Debian Buster (OpenSSL 1.1.1) this does not make a difference,
however using the system default provides better compatibility with
future libssl versions.

Test suite: add new tests for SSL/TLS.

SSL connections are accepted on TCP port 10993.  Also, fix STARTTLS
directive, broken since fba1c36…
