oid_pos(): access table through const pointers
When we are looking up an oid in an array, we obviously don't need to write to the array. Let's mark it as const in the function interfaces, as well as in the local variables we use to derference the void pointer (note a few cases use pointers-to-pointers, so we mark everything const).
