req_vec_num_in_item a requirement vectors number in an item.

Checks the requirement(s) to see if they are active on the given target.
context gives the target (or targets) to evaluate against
reqs gives the requirement vector. The function returns TRUE only if all requirements are active.
context may be NULL. This is equivalent to passing an empty context.
Make sure you give all aspects of the target when calling this function: for instance if you have TARGET_CITY pass the city's owner as the target player as well as the city itself as the target city.
