[Interest] Qt 5.9 and OpenSSL 1.1?

I finally got around to upgrading OpenSSL and getting to work Qt 5.9 with it. It 
required an additional change that I hadn't found in the 5.10 branch: accepting 
the newer version during the configure phase :)


Test-driving it I did notice that the securesocketclient example would crash on 
me, due to which seems to be an oversight (still present in newer code):

Technically it seems that it should be possible when loading the SSL libraries 
at runtime, no?

What about LibreSSL, do they have the same inter-version compatibility issues as 
OpenSSL has, and could you distribute a binary version in your binary packages?
If so, it could be worth the initial investment to start supporting it?
