libfdt: Use zerocopy for safe fdt_header wrapper

Provide a way to get a safe &(mut) fdt_header from any <T: Libfdt(Mut)>.

Instead of manually doing the conversion from the BE-encoded DT fields,
use zerocopy to implement a zero-cost wrapper where each field has a
getter and setter function that transparently handles the endianness.

Combine those to remove the need for unsafe code in Fdt.

Android Virtualization Framework (AVF)

Android Virtualization Framework (AVF) provides secure and private execution environments for executing code. AVF is ideal for security-oriented use cases that require stronger isolation assurances over those offered by Android’s app sandbox.

Visit our public doc site to learn more about what AVF is, what it is for, and how it is structured. This repository contains source code for userspace components of AVF.

If you want a quick start, see the getting started guideline and follow the steps there.
