Marco Trevisan (Treviño) 157f93d2ee girepository: Use size_t for size-related arguments and return types 
We used to use unsigned values, while they should be big enough to old
the data we're handling here, it's cleaner and clearer if we use size_t
as type for such values, as it makes straight forward to understand what
a value should contain. It also makes these values more future proof.
