/**
 * InputStream for handshake data, used internally only. Contains the
 * handshake message buffer and methods to parse them.
 *
 * Once a new handshake record arrives, it is buffered in this class until
 * processed by the Handshaker. The buffer may also contain incomplete
 * handshake messages in case the message is split across multiple records.
 * Handshaker.process_record deals with all that. It may also contain
 * handshake messages larger than the default buffer size (e.g. large
 * certificate messages). The buffer is grown dynamically to handle that
 * (see InputRecord.queueHandshake()).
 *
 * Note that the InputRecord used as a buffer here is separate from the
 * AppInStream.r, which is where data from the socket is initially read
 * into. This is because once the initial handshake has been completed,
 * handshake and application data messages may be interleaved arbitrarily
 * and must be processed independently.
