This should make debugging easier in such cases.

So far, only the Apply-Actions instruction is supported, and only
actions that have identical semantics to OpenFlow 1.0 actions.

OpenFlow actions have always been somewhat awkward to handle.
Moreover, over time we've started creating actions that require more
complicated parsing. When we maintain those actions internally in
their wire format, we end up parsing them multiple times, whenever
we have to look at the set of actions.
When we add support for OpenFlow 1.1 or later protocols, the situation
will get worse, because these newer protocols support many of the same
actions but with different representations. It becomes unrealistic to
handle each protocol in its wire format.
This commit adopts a new strategy, by converting OpenFlow actions into
an internal form from the wire format when they are read, and converting
them back to the wire format when flows are dumped. I believe that this
will be more maintainable over time.
Thanks to Simon Horman and Pravin Shelar for reviews.
