Title: Large Record Sizes for TLS and DTLS with Reduced Overhead

Abstract:
TLS 1.3 records limit the inner plaintext (TLSInnerPlaintext) size to
2^14 + 1 bytes, which includes one byte for the content type. DTLS
1.3 uses the same plaintext size limit. This document defines a TLS
extension that allows endpoints to advertise larger per-direction
maximum inner plaintext sizes, up to 2^30 - 256 bytes, while reducing
overhead in TLS 1.3 and DTLS 1.3 record headers.
