Xiang Li e44e753e66 pkg/idutil: reduce conflict rate from 1% to 0.005% ...

Perviously, we only use 8bits from member identification
in id generation. The conflict rate is A(256,3)/256^3, which
is around 1%. Now we use 16bites to reduce the rate to 0.005%.

We can attach the full member id into id generation if needed...
