OpenSSL_version(OPENSSL_DIR) gives you a nicely formatted string for
display, but if all you really want is the directory itself, you were
forced to parsed the string.
This introduces a new function to get diverse configuration data from
the library, OPENSSL_info(). This works the same way as
OpenSSL_version(), but has its own series of types, currently
including:
OPENSSL_INFO_CONFIG_DIR returns OPENSSLDIR
OPENSSL_INFO_ENGINES_DIR returns ENGINESDIR
OPENSSL_INFO_MODULES_DIR returns MODULESDIR
OPENSSL_INFO_DSO_EXTENSION returns DSO_EXTENSION
OPENSSL_INFO_DIR_FILENAME_SEPARATOR returns directory/filename separator
OPENSSL_INFO_LIST_SEPARATOR returns list separator
For scripting purposes, this also adds the command 'openssl info'.
