Merge branch 'ife-to-module' 



Yotam Gigi says:

====================
Extract IFE logic to module

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.
