Use stdint types where reasonable

Browse source 
Using uint32_t instead of unsigned int for the unpacked work struct ensures
the code is working correctly on ABIs with ints narrower than 32 bits.

While this would constitute a API/ABI change on some systems in theory,
most likely all systems using libuecc so far have uint8_t == unsigned char
and uint32_t == unsigned int.

Also, coding style cleanup.
