ERR: Drop or deprecate dangerous or overly confusing functions

ERR_get_error_line() is deprecated, and ERR_get_error_func() and
ERR_get_error_data() are removed in favor of ERR_get_error_all(),
since they pop the error record, leaving the caller with only partial
error record data and no way to get the rest if the wish.

If it's desirable to retrieve data piecemeal, the caller should
consider using the diverse ERR_peek functions and finish off with
ERR_get_error().
