We already verified that the attribute parser tables were correctly
sorted. Now also verify that the command decoders are too.
While here move the assertions into a constructor so we only run them once.
Introduce a PF netlink command decoder table mapping PFNL commands to
their attribute decoder sets. This replaces the existing switch-based
dispatch and makes it easier to add support for additional PF netlink
commands.
