test/test_protocol: add fee support.

Browse Source 
We simply record how many fee changes there are, rather than supporting
a particular level.

Fees are tricky: it's a noop to apply them when incoming, but we apply them
when they've been acked.  Unlike HTLC modifications, which are symmetric,
fee updates only apply when returning to the originating node.
