Marshal, unmarshal. For many cql types unmarshaling data that have bigger len than cql type, do not return an error.

[illia-li]

Currently the functions for Unmarshaling many cql types, do not return an error, then the data has a longer length than the cql type.
Type list: TypeBoolean, TypeTinyInt, TypeSmallInt, TypeInt, TypeBigInt, TypeCounter, TypeDouble, TypeFloat, TypeInet, TypeTime, TypeDate, TypeTimestamp, TypeVarint, TypeDuration.

Testcode:

func TestDataOverflow(t *testing.T) {
	types := []TypeInfo{
		NativeType{proto: 2, typ: TypeBoolean},
		NativeType{proto: 2, typ: TypeTinyInt},
		NativeType{proto: 2, typ: TypeSmallInt},
		NativeType{proto: 2, typ: TypeInt},
		NativeType{proto: 2, typ: TypeBigInt},
		NativeType{proto: 2, typ: TypeCounter},
		NativeType{proto: 2, typ: TypeDouble},
		NativeType{proto: 2, typ: TypeFloat},
		NativeType{proto: 2, typ: TypeInet},
		NativeType{proto: 2, typ: TypeTime},
		NativeType{proto: 2, typ: TypeDate},
		NativeType{proto: 2, typ: TypeTimestamp},
		NativeType{proto: 2, typ: TypeVarint},

		NativeType{proto: 2, typ: TypeDuration},
	}

	noErrs := make([]string, 0)
	for _, tp := range types {
		data := []byte{1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 255, 255, 255, 255, 255, 255, 255, 252}
		val := tp.New()
		if err := Unmarshal(tp, data, val); err != nil {
			continue
		}
		if val != nil {
			val = dereference(val)
		}
		noErrs = append(noErrs, fmt.Sprintf("type:<%s> - value: <%v>", tp.Type().String(), val))
	}
	if len(noErrs) > 0 {
		t.Errorf("\nOut of %d test cases, %d cases without errors:\n%s", len(types), len(noErrs), strings.Join(noErrs, "\n"))
	}
}
