Occasionally, it may be useful for callers to know the number of object IDs in an oidset. Right now, the only way to compute this is to call 'kh_size' on the internal 'kh_set_oid_t'. Similar to how we wrap other 'kh_*' functions over the 'oidset' type, let's allow callers to compute this value by introducing 'oidset_size'. We will add its first caller in the subsequent commit.
