From 7d433206cf7de8f28aa2d169ed25cd401fcfc413 Mon Sep 17 00:00:00 2001

Subject: [PATCH] libarchive: Add headers to adapt between OpenSSL 1.1 and older versions
Add private forwarding headers for `openssl/{evp,hmac}.h` to give us a
central place to add adaptation code to work across multiple
incompatible OpenSSL versions. Provide compatibility implementations of
some OpenSSL 1.1 APIs when using older OpenSSL versions.
