Cast the 64-bit offset parameter of PartialRead() to a size_t local variable after verifying that the offset is less than or equal to data->full_size (a size_t). From that point on, use the size_t local variable as the offset exclusively. Note that size_t is a 32-bit unsigned integer on 32-bit platforms. Audit the entire PartialRead() function for integer overflows. Fix AOMediaCodec#1165.
