// Reads the available input in the source manager's input buffer until either

// the end of the next SOS marker or the end of the input.

// The corresponding fields of cinfo are updated with the processed input data.

// Upon return, the input buffer will be at the start or at the end of a marker

// data segment (inter-marker data is allowed).

// Return value is one of:

//   * JPEG_SUSPENDED, if the current input buffer ends before the next SOS or

//       EOI marker. Input buffer refill is handled by the caller;

//   * JPEG_REACHED_SOS, if the next SOS marker is found;

//   * JPEG_REACHED_EOR, if the end of the input is found.
