AP_Math: added unsigned versions of constrain functions

Browse Source 
sometimes it really does matter that we use constrain_uint32() instead
of constrain_int32(). For example, if we have a value like 0xFFFFFFFF
then the result will be very different

we should use unsigned constrain when dealing with unsigned values
