Questions about manifest.c

[PengZheng]

1. manifest->mainAttributes is dropped in manifest_clone.
2. manifest->attributes seems empty most of the time: the while loop after manifest_readAttributes(manifest, manifest->mainAttributes, file) seems NEVER entered.

       manifest_readAttributes(manifest, manifest->mainAttributes, file);
       // fgets almost always returns NULL
       while (status==CELIX_SUCCESS && fgets(lbuf, sizeof(lbuf), file) != NULL) {
               }

3. The line continuation logic may lead to stack overflow for malicious manifest.

I don't understand why is manifest->attributes there?
