Commit Message

A later patch will require to easily exclude CT_STATE_KERNEL from a genuine
a ct->state read CT_STATE_KERNEL, which requires that value being non-zero
and exclusive with the other CT_STATE_* values.

This increases the size of the CT_STATE region of the ct->state variable by
two bits.
