Consider adding fallback support for WolfSSL
WolfSSL has an OpenSSL compatibility layer, so if a distribution can't offer Icecast linked with OpenSSL, using WolfSSL might be a possibility. I've made and tested a minimal patch, and with git master of WolfSSL Icecast is fully functional.
Would you consider adding support for it? It was mentioned that this might be more fitting for the 2.4 series.
Example patch attached (note this is not the version I was testing).
