ERR_peek_last_error
    ERR_peek_last_error_line
    ERR_peek_last_error_line_data
(supersedes ERR_peek_top_error).

Rename OPENSSL_NO_OLD_DES_SUPPORT into OPENSSL_DISABLE_OLD_DES_SUPPORT
because OPENSSL_NO_... indicates disabled algorithms (according to
mkdef.pl).

ERR_get_error() returns the last error code from the thread's error
ERR_get_error() returns the earliest error code from the thread's error
queue and removes the entry. This function can be called repeatedly
until there are no more error codes to return.
ERR_peek_error() returns the last error code from the thread's
ERR_peek_error() returns the earliest error code from the thread's
error queue without modifying it.
ERR_peek_last_error() returns the latest error code from the thread's
error queue without modifying it.
