From 6f23daea4391c2db8bc27d2e4cb42eac02368822 Mon Sep 17 00:00:00 2001
From: Brad King <brad.king@kitware.com>

Subject: [PATCH] libarchive: Add support for building with OpenSSL 1.1
OpenSSL 1.1 made some CTX structures opaque. Port our code to use the
structures only through pointers via OpenSSL 1.1 APIs. Use our adaption
layer to make this work with OpenSSL 1.0 and below.
Patch-by: Tomas Mraz <tmraz@redhat.com>
Patch-from: https://bugzilla.redhat.com/1383744
