Qt5-network fails to build with LibreSSL 2.7

When building qt5-network with LibreSSL 2.7 it will fail due to slight differences in the API between OpenSSL 1.1 and LibreSSL 2.7.

In LibreSSL 2.7 the OpenSSL 1.1 (and much of 1.0.2) API was added, requiring far fewer changes to make software using libssl/libcrypto to compile. It is expected most of the remaining differences will be addressed in 2.8.

I keep an overview of status of LibreSSL 2.7 fall-out on https://wiki.freebsd.org/LibreSSL/2.7

Attached are the patches that are currently maintained for FreeBSD ports. These also fix issues where non-base (/lib /usr/lib) libraries are wanted for building.
