We'd expect stop_commands to stop all commands, but we (ab)used
CMD_SEND_HTLC_FULFILL to send us R values even in closing state.

By terminating in either NORMAL state, we halve the time to run the
coverage test.

Once both are longer listening to their packets, we don't need to
simulate all variants of what each are doing.

For loop detection, we don't need entire state. So extract a core,
which we can put in hash table.

This requires our state exerciser to be smarter. In particular, it
needs to track individual HTLCs rather than just sending random
inputs.
To do this:
1) We keep data associated with packets as they flow (where
those packets are associated with HTLCs).

These tests are wrong, and are handled properly anyway when they
fire (the other one is disabled).

We should always have a packet in flight unless we're in the two
waiting-for-anchor-to-mature states, or at the top of the main loop.

The state machine is infinite, but if we eliminate the normal inner
state loop, and a couple of other unusual cases where inputs can
repeat, we should be able to traverse it all.
This is slower than simply stopping when we hit a repeated state
though.
