detect: issue drop to root packet in all cases

Browse Source 
Update DROP action handling in tunnel packets. DROP/REJECT action is set
to outer (root) and inner packet.

Check action flags both against outer (root) and inner packet.

Remove PACKET_SET_ACTION macro. Replace with RESET for the one reset usecase.
The reason to remove is to make the logic easier to understand.

Reduce scope of RESET macros.

Rename PacketTestAction to PacketCheckAction except in unittests. Keep
PacketTestAction as a wrapper around PacketCheckAction. This makes it
easier to trace the action handling in the real code.

Fix rate_filter setting actions directly.

General code cleanups.

Bug: #5571.
