DalvikRunner can run a test as an android.app.Activity & PathClassLoader.toString change

SUMMARY:
- PathClassLoader.toString prints path
- DalvikRunner --mode activity now working
- new DalvikRunner --no-clean vs --no-clean-after behavior

DETAILS

Dalvik runtime change
    Changed PathClassLoader.toString to print the class loaders path
    Also fixed variable name in commented out debug code
	libcore/dalvik/src/main/java/dalvik/system/PathClassLoader.java

Dalvik Runner changes

    Mode is the new abstract superclass of the existing Vm
    class. ActivityMode is for the new Mode of running as a Activity
    on the device. Vm is now a subclass of Mode and its JavaVm and
    DeviceDalvikVm still exist although some code has been refactored
    into the new Environment clases (see below)

	libcore/tools/runner/java/dalvik/runner/Mode.java
	libcore/tools/runner/java/dalvik/runner/ActivityMode.java
	libcore/tools/runner/java/dalvik/runner/DeviceDalvikVm.java
	libcore/tools/runner/java/dalvik/runner/JavaVm.java
	libcore/tools/runner/java/dalvik/runner/Vm.java

    Environment and its subclasses EnvironmentHost and
    EnvironmentDevice allow us to reuse some common code between the
    two different device modes (ActivityMode and
    DeviceDalvikVm). Basically code that was more about where and how
    to do things based on where the code was running as opposed to how
    the code was running moved to the Environment classes. For
    example, prepare() logic for /sdcard/ and ADB code in general.

    Adding new files

    Aapt is a wrapper for "aapt" similar to Adb and Dx
	libcore/tools/runner/java/dalvik/runner/Aapt.java

    Added Adb.install and Adb.uninstall methods
    Changed from using File.toString to File.getPath for clarity
	libcore/tools/runner/java/dalvik/runner/Adb.java

    CodeFinder has been extended so that Driver can ask finders what
    they need to build and run, specifically through the new
    getRunnerJava and getRunnerClasspath. (As part of this
    NamingPatternCodeFinder's runnerClass was changed to
    getRunnerClass for consistency with the superclass.) This was
    important for running as an Activity because we want to minimize
    what we pack into the APK file because of the "dx --dex" runtime
    and not just pull in all possible runners and supporting
    libraries. TestRun objects also hold onto this information from
    their finders.

    TestRunner TestRunner's className is now testClass to clarifiy it
    from the runnerClass.

    Classpath now has a Collection.of and Collection.addAll that take
    a Collection<File> instead if just a File...

	libcore/tools/runner/java/dalvik/runner/Classpath.java

    Added Command.args(File arg) to avoid a lot of
    args(file.getPath())

	libcore/tools/runner/java/dalvik/runner/Command.java

     Option --clean has expanded to --clean-before, --clean-after, and
     --clean. Now --no-clean will remove nothing as Elliot
     requested. --no-clean-after is now what is useful for
     DalvikRunner debuggin. Default is still to clean before and
     after.

	libcore/tools/runner/java/dalvik/runner/DalvikRunner.java

    Moved Vm.DALVIK_RUNNER_HOME to DalvikRunner.HOME.
    /tmp/<UUID> paths are now /tmp/dalvikrunner/<UUID> paths are easier cleanup.

	libcore/tools/runner/java/dalvik/runner/DalvikRunner.java

    Driver was changed to use a ExecutorCompletionService around the
    ExecutorService so that exceptions from the execute threads could
    be reported on the main thread.

	libcore/tools/runner/java/dalvik/runner/Driver.java

    We now build the testrunner before the test so that its classes
    will be around to be packed into APK files.

	libcore/tools/runner/java/dalvik/runner/Driver.java

    Dx.dex now takes File arguments instread of Strings.  Dx.dex also
    needs to pass additional memory arguments to not run out of memory
    building the big dex for the APK. The values I used where from the
    build/core/definitions.mk

	libcore/tools/runner/java/dalvik/runner/Dx.java

    postCompile was split into postCompileTestRunner and
    postCompileTest because the packaging requires are very different
    in each case for ActivityMode. Specifically, the test runner is
    not post-packaged seperately, but packaged in the APK with each
    test.

    Changed testClass to test to avoid collision with new superclass field

	libcore/tools/runner/java/dalvik/runner/JtregRunner.java
	libcore/tools/runner/java/dalvik/runner/MainRunner.java

    Added @SuppressWarnings("unchecked")

	libcore/tools/runner/java/dalvik/runner/OptionParser.java

    New android.app.Activity based on Elliot's TestAPK. It encapsulates an
    ActivityRunner that invokes the appropriate TestRunner based on test.properties.

	libcore/tools/runner/java/dalvik/runner/TestActivity.java

    New class that shared contains (old and some new) between the
    DalvikRunner and the TestRunner.

	libcore/tools/runner/java/dalvik/runner/TestProperties.java

    Regression test script for debugging the matrix of various
    DalvikRunner modes and test types:
