oid_array: use size_t for iteration

peff · gitster · commit eccce5253b9b · 2020-03-30T10:59:08.000-07:00
The previous commit started using size_t for our allocations. There are
some iterations that use int or unsigned, though. These aren't dangerous
with respect to memory, but they could produce incorrect results.
