 // A wrapper around a memory buffer that allows circular read and write with a
 // selectable wrapping position. Buffer layout (after wrap; H is header):
 // -----------------------------------------------------------
 // | H | Beginning           | End           | Middle        |
 // -----------------------------------------------------------
 //  ^---- Non-wrapping -----^ ^--------- Wrapping ----------^
 // The non-wrapping part is never overwritten. The wrapping part will be
 // circular. The very first part is the header (see the BufferData struct
 // below). It consists of the following information:
 // - Length written to the buffer (not including header).
 // - Wrapping position.
 // - End position of buffer. (If the last byte is at x, this will be x + 1.)
 // Users of wrappers around the same underlying buffer must ensure that writing
 // is finished before reading is started.
