     * Initiates a package state mutation request, returning the current state as known by
     * PackageManager. This allows the later commit request to compare the initial values and
     * determine if any state was changed or any packages were updated since the whole request
     * was initiated.
     *
     * As a concrete example, consider the following steps:
     * <ol>
     *     <li>Read a package state without taking a lock</li>
     *     <li>Check some values in that state, determine that a mutation needs to occur</li>
     *     <li>Call to commit the change with the new value, takes lock</li>
     * </ol>
     *
     * Between steps 1 and 3, because the lock was not taken for the entire flow, it's possible
     * a package state was changed by another consumer or a package was updated/installed.
     *
     * If anything has changed,
     * {@link #commitPackageStateMutation(PackageStateMutator.InitialState, Consumer)} will return
     * a {@link PackageStateMutator.Result} indicating so. If the caller has not indicated it can
     * ignore changes, it can opt to re-run the commit logic from the top with a true write lock
     * around all of its read-logic-commit loop.
     *
     * Note that if the caller does not care about potential race conditions or package/state
     * changes between steps 1 and 3, it can simply opt to not call this method and pass in null
     * for the initial state. This is useful to avoid long running data structure locks when the
     * caller is changing a value as part of a one-off request. Perhaps from an app side API which
     * mutates only a single package, where it doesn't care what the state of that package is or
     * any other packages on the devices.
     *
     * Important to note is that if no locking is enforced, callers themselves will not be
     * synchronized with themselves. The caller may be relying on the PackageManager lock to
     * enforce ordering within their own code path, and that has to be adjusted if migrated off
     * the lock.
