ofp-actions: Make union ofp_action more generic.
Make union ofp_action more generic by allowing it to be used for
all actions. OFP_ACTION_ALIGN (which is 8, as the sizeof(union
ofp_action) used to be) is now used where sizeof union ofp_action
was used before. On the same note, variable name 'n_actions' is
changed to 'max_actions' as the number of actions cannot be simply
divided when actions have various sizes.
