When updated to work with OpenSSL 3.0, the host tools lost their compatibility with previous versions (1.x) of OpenSSL. This is mainly due to the fact that 1.x APIs became deprecated in 3.0 and therefore their use cause compiling errors. In addition, updating for a newer version of OpenSSL meant improving the stability against security threats. However, although version 1.1.1 is now deprecated, it still receives security updates, so it would not imply major security issues to keep compatibility with it too. This patch adds backwards compatibility with OpenSSL 1.x versions by adding back 1.x API code. It defines a macro USING_OPENSSL3, which will select the appropriate OpenSSL API version depending on the OpenSSL library path chosen (which is determined by the already-existing OPENSSL_DIR variable). In addition, cleanup items were packed in functions and moved to the proper modules in order to make the code more maintainable and legible.
