Clean up emergency console and use panic for unexpected exceptions.

This removes `eprintln`, which was easy to misuse and not really sound.
Instead, use `emergency_uart`, which has been made unsafe with a clearly
documented safety requirement that it can only be called when the normal
UART instance will never be used again, e.g. just before rebooting.
Also changed `emergency_uart` to return an error rather than panicking,
so panic handler can ignore the error.

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.
