Extract ife logic from the tc_ife action into an independent module, and make the tc_ife action use it. This way, the ife encapsulation can be used by other modules other than tc_ife action.
v1->v2: Fix duplicate symbol error by introducing a new patch that makes the original symbol static. The symbol ife_tlv_meta_extract is exported in act_ife, though not being used by any other module. As the symbol is being moved to the new ife module, introducing the new module creates duplicate symbol. To fix it, add a new patch (1/3) that makes the ife_tlv_meta_extract symbol static in act_ife, thus the symbol does not collide.
