+Subject: [PATCH 01/23] refactor RaucBundleAccessArgs->http_info_headers from
+ GStrv to GPtrArray
+
+Keeping it as a GPtrArray makes it it easy to modify after the initial
+creation and also avoids the need to keep a trailing NULL pointer. In a
+follow-up commit, we'll make assemble_info_headers usable for bundle
+inspection as well.
