ext/record_size_limit: new extension
This implements the record_size_limit extension as defined in RFC 8449.
Although it obsoletes the max_record_size extension, for compatibility
reasons GnuTLS still sends it on certain occasions. For example, when
the new size is representable as the codepoint defined for
max_record_size.
