setkey uses pfkey_open to open a socket. But setkey doesn't close the
socket.
The libipsec functions are used only by user space applications (setkey
and racoon). Adding the wrapper for socket makes sure that the opened
socket is registered and closes if the application exits.
Fixes#4404
Git mirror commit 59f44d20be3f99d181ca742e636d45fc39ec982b.
This commit updates OpenSSL to version 1.1.1. This required an update
of racoon which uses some internal stuff from OpenSSL and seems to be
mostly unmaintained, e.g. there is update in the FreeBSD ports to cope
with OpenSSL 1.1.1.
Update #3472.
