dpif: Log each operation in dpif_operate().
		
Without logging of operation groups, it becomes more difficult to debug
problems related to flow setups, since those go through operation groups.

dpif: Change provider interface to consistently use operation structs.
		
Until now, a "flow put" has represented its parameters in two different
ways, depending on whether it was coming from dpif_flow_put() or from
dpif_operate(), and similarly for an "execute" operation.  This commit
adopts the operation struct consistently within the dpif provider
interface, which seems cleaner.

This commit also factors out logging for flow puts and executes, which
is useful in the following commit.

This doesn't change the dpif client interface, since the two forms are
more convenient for clients than always filling out an operation struct.

dpif: Factor 'type' and 'error' out of individual dpif_op members.
		
I'd like to change ->dpif_flow_put() and ->dpif_execute() in the dpif
provider to take the structures of the same names as parameters, instead of
passing them discrete parameters, because this seems like a more sensible
way to do things internally than to have two different ways to pass the
parameters.  It might even simplify code slightly.  But ->flow_put() and
->execute() wouldn't want the 'type' (because it's implied by the function
being called) or 'error' (because it would be the same as the return
value).  Although of course they could just ignore those members, it seems
slightly cleaner to omit them entirely, as this change allows.
