When a packet has more than one change-of-flow instruction, only the first
one to branch is considered. We use the branch_taken variable to keep
track of this.
However, when there is a single cof instruction, we don't need the same
amount of bookkeeping.
We add the pkt_has_multi_cof member to the Packet structure, and pass this
information to the needed functions.
When there is a generated helper function with cof, the generator will
pass this pkt_has_multi_cof as a runtime value.
