Stop the abuse of CURLE_FAILED_INIT as return code for things not being init related by introducing two new return codes: CURLE_NOT_BUILT_IN and CURLE_UNKNOWN_OPTION CURLE_NOT_BUILT_IN replaces return code 4 that has been obsoleted for several years. It is used for returning error when something is attempted to be used but the feature/option was not enabled or explictitly disabled at build-time. Getting this error mostly means that libcurl needs to be rebuilt. CURLE_FAILED_INIT is now saved and used strictly for init failures. Getting this problem means something went seriously wrong, like a resource shortage or similar. CURLE_UNKNOWN_OPTION is the option formerly known as CURLE_UNKNOWN_TELNET_OPTION (and the old name is still present, separately defined to be removed in a very distant future). This error code is meant to be used to return when an option is given to libcurl that isn't known. This problem would mostly indicate a problem in the program that uses libcurl.
