temp_value was a file-scope global shared by every CDI parse. The boxart
scraper opens discs on its own thread, so it can parse a CDI while a
game is loading and corrupt the other parse's reads.
Use a local in each function. It's a uint32_t initialized to 0 because
every read into it is 4 bytes; a local unsigned long would leave the top
half uninitialized on LP64.
