f459828358 Annotations for Bluetooth broadcast intents.
Recent work has been using Error Prone rules and annotations to
reflect the current state of permission enforcement across the
Bluetooth stack, and we're now in a position were we can add new
permission enforcement that had been missing.

We've currently standardized on saying that APIs that return device
or Bluetooth state information (without sharing details about any
particular remote Bluetooth device) do not need to be permission
protected.

Bug: 183626724
Test: ./build/soong/soong_ui.bash --make-mode Bluetooth RUN_ERROR_PRONE=true

71463a4cb1 Error Prone for RequiresPermission across AIDL.
We've had @RequiresPermission annotations across public APIs for many
years, but we've never built out the tooling to validate that the
service implementations actually enforced those permissions.

This change adds an Error Prone checker that does bi-directional
validation of these annotations, confirming that AIDL implementations
enforce the permissions, and that AIDL callers carry those
annotations through any indirect call-paths.

Currently, enforcement validation is best-effort, since it assumes
that any enforcement referencing the annotated permissions is enough
to pass; it doesn't attempt any code flow analysis.  It also doesn't
understand concepts like Binder.clearCallingIdentity().

To begin using this checker, simply begin annotating your AIDL files
using a strategy like this:

    @JavaPassthrough(annotation="@android.annotation.RequiresPermission(android.Manifest.permission.BLUETOOTH_PRIVILEGED)")
    void aidlMethod();

86ba608e34 Add tests for framework-specific Error Prone.
We recently started writing custom Error Prone checkers, but it's
been painfully slow to develop against the giant source tree, so
this change adds tests to verify existing behavior and to enable TDD
for future checkers.
