Title: #570: p11_child: add OpenSSL support
OK, I'm done with the code review. tl;dr the zero timeut is confusing and the
commented out code needs to be removed. I'm struggling a bit with testing with Yubikey
for some reason, but let me fight with it until tomorrow at least, if I can't figure
out everything by myself, I'll ping you for help..
