We fix 3 problems with safestack: - Including an openssl header file without linking against libcrypto can cause compilation failures (even if the app does not otherwise need to link against libcrypto). See issue #8102 - Recent changes means that applications in no-deprecated builds will need to include additional macro calls in the source code for all stacks that they need to use - which is an API break. This changes avoids that necessity. - It is not possible to write code using stacks that works in both a no-deprecated and a normal build of OpenSSL. See issue #12707. Fixes #12707 Contains a partial fix for #8102. A similar PR will be needed for hash to fully fix.
