Replace uptr by usize/SIZE_T in interfaces

Replace uptr by usize/SIZE_T in interfaces

For some targets uptr is mapped to unsigned int and size_t to unsigned
long and sizeof(int)==sizeof(long) holds.  Still, these are distinct
types and type checking may fail.  Therefore, replace uptr by
usize/SIZE_T wherever a size_t is expected.
