IPSEC: API modernisation
- use enums to enumerate the algoritms and protocols that are supported - use address_t types to simplify encode/deocde - use typedefs of entry objects to get consistency between add/del API and dump Change-Id: I7e7c58c06a150e2439633ba9dca58bc1049677ee Signed-off-by: Neale Ranns <nranns@cisco.com>
