  To: dev
  Cc: akhil.goyal, roy.fan.zhang, arkadiuszx.kusztal, jerin.jacob, fiona.trahe

This patch changes the key pointer data types in cipher, auth,
and aead xforms from "uint8_t *" to "const uint8_t *" for a
more intuitive and safe sessionn creation.

Although it is a relative big patch, but I believe it is the
right thing to do towards a safer and better DPDK Cryptodev,
and we should have done this long time ago.

I have been trying to avoid the problems that may cause due
to the bug/missed updates places. However, due to lacking the
hardware I was only able to test the PMDs I have. So
please forgive me if I missed updating certain drivers/tests. I
will amend that.
