// All data that a request stream receives falls into one of two categories:
//  * "body", that is, DATA frame payload, which the QuicStreamSequencer must
//    buffer until it is read;
//  * everything else, which QuicSpdyStream immediately processes and thus could
//    be marked as consumed with QuicStreamSequencer, unless there is some piece
//    of body received prior that still needs to be buffered.
// QuicSpdyStreamBodyManager does two things: it keeps references to body
// fragments (owned by QuicStreamSequencer) and offers methods to read them; and
// it calculates the total number of bytes (including non-body bytes) the caller
// needs to mark consumed (with QuicStreamSequencer) when non-body bytes are
// received or when body is consumed.
