tar/storage: work with raw (invalid utf8) names

Browse source 
When the entry name is not UTF-8, for example ISO-8859-1, then store the
raw bytes.
To accommodate this, we will have getters and setters for the entry's
name now. Since this most heavily affects the json marshalling, we'll
double check the sanity of the name before storing it in the JSONPacker.
