int: Add value accessors: mp_obj_int_get() & mp_obj_int_get_checked().

Browse Source 
mp_obj_int_get() can be used when just full resolution of C machine_int_t
is required (returns truncated value of long int). mp_obj_int_get_checked()
will throw exception if Python int value not representable in machine_int_t.
