  The rte_security lib has introduced replay_win_sz,
so it can be removed from the rte_ipsec lib.

The relaved tests,app are also update to reflect
the usages.

Note that esn and anti-replay fileds were earlier used
only for ipsec library, they were enabling the libipsec
by default. With this change esn and anti-replay setting
will not automatically enabled libipsec.

Hi Konstantin,

I had requested some changes in v5 which are there in this patch.
Could you please review this again? I plan to merge it today.

Thanks,
Akhil

That actually will break lib-mode functional tests at:
examples/ipsec-secgw/test/
Due to my laziness I enabled in them library mode via '-w' option,
as that moment legacy mode didn't support replay window...
As these patches already applied, I'll send the fix in a new one in next few.

Ok, but what to do for the devices that don't support esn or replay_win_sz?
Should we add some check? Either to the app, or preferably into rte_security
level at  rte_security_session_create()?

No issues, I will squash your changes with the original patch as it is not applied 
On master.

Ideally app should check the capability of the device before setting it.
