The bit accounting functions aom_reader_tell() and aom_reader_tell_frac() return the number of bits and 1/8th bits respectively. This patch changes the return type from ptrdiff_t which is signed to uint32_t which is unsigned. The size_t type is not used since we only care about the number of bits or 1/8 bits per entropy coder context and we don't expect to code more than 512 megabits per tile.
