Change all calls to getenv() inside libcrypto to use a new wrapper function that use secure_getenv() if available and an issetugid then getenv if not. CPU processor override flags are unchanged. Extra checks for OPENSSL_issetugid() have been removed in favour of the safe getenv. Reviewed-by: Bernd Edlinger <bernd.edlinger@hotmail.de> (Merged from https://github.com/openssl/openssl/pull/7047)
