This change sets LOCAL_SDK_VERSION for all packages where
this is possible without breaking the build, and
LOCAL_PRIVATE_PLATFORM_APIS := true otherwise.

Setting one of these two will be made required soon, and this
is a change in preparation for that. Not setting LOCAL_SDK_VERSION
makes the app implicitly depend on the bootclasspath, which is
often not required. This change effectively makes depending on
private apis opt-in rather than opt-out.

Statically including legacy-android-test leads to duplicate classes
which causes build time problems (with Proguard) and runtime problems on
older SDK versions. This change:
* Stops statically including legacy-android-test.
* Adds compile time dependencies on andoid.test.base, android.test.mock
  and android.test.runner where necessary.
* Adds <uses-library android:name="android.test.runner"/> to any
  affected package to ensure that the classes that were included by
  legacy-android-test are still available at runtime. That also adds a
  dependency on android.test.base and android.test.mock.

The following change descriptions were generated automatically and so
may be a little repetitive. They are provided to give the reviewer
enough information to check the comments match what has actually been
changed and check the reasoning behind the changes.

* tests/Android.mk
    Added 'android.test.base' to LOCAL_JAVA_LIBRARIES because
    LegacyCameraTests's source depends on its classes and because of
    these changes they are no longer present on the compilation path.

    Removed legacy-android-test from LOCAL_STATIC_JAVA_LIBRARIES
    because statically including the classes in LegacyCameraTests
    results in duplicate classes which leads to build time and compile
    time issues.

In preparation for removing junit classes from the Android API
the legacy-test target will be removed from the
TARGET_DEFAULT_JAVA_LIBRARIES. This change adds explicit
dependencies on junit and/or legacy-android-test to ensure that
modules will compile properly once it is removed.

The SDK needs a camera app that does not require GPU acceleration.
The Camera app from 4.0.4 meets these requirements.

Front camera preview is mirrored. Change to use matrix to
calculate the focus area. So the focus area will be
correct in all orientations in front or back camera.

This prevents fast flickering between two orientation states, which
can result in ugly UI issues, especially with the preview thumbnail.

The "Intent.FLAG_ACTIVITY_CLEAR_TOP" should be added in the intent for switching modes. This flag
ensures there is only 1 instance of the same activity. This behavior is the same as how we do in the
app.

The code about focus is complicated and scattered around.
Move the code to a new class, so it is easier to maintain.
