Wire up a tracer for Android IP Protection Auth client library

This CL adds the first version of the IP Protection auth client
library and tests the end to end data flow by mocking the auth service.
An Android instrumentation test is added to run the test.
In this initial version, the IPC methods just respond with the same
payload that is passed in the request.

Context:
As part of IP Protection in Android, WebView and Cronet needs to
request for authentication tokens from a system provided
Android service in order to talk to the IP Protection proxy server.
This client library provides a wrapper that handles the IPC to this
authentication service.

Currently, this component is intended to be used by both WebView
and Cronet.

Test: "autoninja -C out/Default ip_protection_auth_test_apk && out/Default/bin/run_ip_protection_auth_test_apk"

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
