Suggest fuzzer for zbar_image_set_data() and zbar_image_convert().

[autofuzzoss]

I suggest this fuzzer for continuous vulnerability checks.

#include <gtest/gtest.h>
#include <stdio.h>
#include <stdlib.h>

#include <zbar.h>
#include "FuzzedDataProvider.h"

using namespace zbar;

extern "C" int LLVMFuzzerTestOneInput(const uint8_t *data, uint32_t size) {
  FuzzedDataProvider provider(data, size);
  auto autofuzz0 = provider.ConsumeRemainingBytesAsString();

  zbar_image_t *img = zbar_image_create();
  if(!img)
    return 0;
  zbar_image_set_size(img, 8, 8);
  zbar_image_set_format(img, zbar_fourcc('J', 'P', 'E', 'G'));
  zbar_image_set_data(img, autofuzz0.c_str(), autofuzz0.size(), NULL);
  zbar_image_t *test = zbar_image_convert(img, zbar_fourcc('Y', '8', '0', '0'));
  if(!test)
    return 0;
  free(img);
  free(test);
  return 0;
}
