mkvparser::UnserializeUInt() assumes that unsigned values never have their high bit set. This is too limiting for UUIDs. In addition, the Chapters::Atom::Parse() method would truncate a "negative" 64-bit UUID value to 32 bits and return the truncated value as a status code. This value then might or might not be treated as an error by the caller depending on whether the truncated value was itself negative. Change-Id: I15624ac62d0b02691a1405ee6a5f7eb441b3bc48
