NetBSD-8 release notes items

Below list needs to be expanded about ARM changes.
Then expanded to be readable by an average technically inclined person.
Then reordered for most cool things on top.

• PaX MPROTECT (W^X) memory protection enforced by default on some architectures with fine-grained memory protection and suitable PLT formats: i386, amd64, evbarm, landisk, pmax
• PaX ASLR enabled by default on: i386, amd64, evbarm, landisk, pmax, sparc64
