      Don't allow fragmented alerts · bd990e25

      An alert message is 2 bytes long. In theory it is permissible in SSLv3 -
      TLSv1.2 to fragment such alerts across multiple records (some of which
      could be empty). In practice it make no sense to send an empty alert
      record, or to fragment one. TLSv1.3 prohibts this altogether and other
      libraries (BoringSSL, NSS) do not support this at all. Supporting it adds
      significant complexity to the record layer, and its removal is unlikely
      to cause inter-operability issues.
      
      The DTLS code for this never worked anyway and it is not supported at a
      protocol level for DTLS. Similarly fragmented DTLS handshake records only
      work at a protocol level where at least the handshake message header
      exists within the record. DTLS code existed for trying to handle fragmented
      handshake records smaller than this size. This code didn't work either so
      has also been removed.
