Switching to OpenSSL is difficult or impossible in many cases because
a lot of libraries pull in libssl/libcrypto.

Generally you can't mix code compiled against OpenSSL and code compiled
against LibreSSL in the same process (e.g. a library built against one
used in an executable built against the other).

This shows QTls code (which expects libressl) calling into functions
coming from openssl's libraries, that's not going to work.

What's failing with libressl? Do you have a (non-working) diff?
