Changes

android remote adb test fixes: (1) Add connect; (2) Remove overriding explicit BOOTCLASSPATH, use default.

(2) Android 4.0.3 LEB 12.02 / Pandaboard requires the original BOOTCLASSPATH,
    otherwise dependencies are broken and dalvikvm crashes.

    Adding 'our' ant-junit-all.apk to 'complete' the set of our required junit/ant classes
    seems to work well on V. 2.3.6 (Samsung Galaxy S) and V. 4.0.3.

Stabilize open InputStream's / Closeable's: Decorate w/ try-finally and close within the latter

android remote test script: panda02 is my default test machine

Allow GLUEGEN_CPPTASKS_FILE to be relative to gluegen.root ; Load gluegen-cpptasks-base.xml in custom files w/ gluegen.root.abs-path.

Fix rel GLUEGEN_CPPTASKS_FILE commit e617834dcabdb83f383a2d2a82fcd2d9d987c154

Intro.: PropertyAccess ; Added safe PropertyAccess for JNILibLoaderBase, Platform, IOUtil, ..

- Intro.: PropertyAccess
  - Base class of all Debug impl, reduces redundancies.

  - jnlpAlias'ed trusted property is queried within local AccessControlContext
    to avoid 'JRE' implementation differences (should not be required).

  - throw NPE and IllegalArgumentException for invalid property key

- Added safe PropertyAccess
  - JNILibLoaderBase: sun.jnlp.applet.launcher
  - Platform: jogamp.gluegen.UseTempJarCache
  - IOUtil: java.io.tmpdir

SecurityUtil: Generalize cert validation and AccessControlContext query; PropertyAccess: Fix security code, grant access to common 'trusted' properties

- SecurityUtil
  - Generalize cert validation for JAR and property access
  - Grant access to common AccessControlContext for 'same' cert

- PropertyAccess:
  - Fix security code: Passing the current AccessControlContext from the caller
    didn't include priviledges.

  - Grant access to common 'trusted' properties,
    which removes the need of passing the AccessControlContext for general properties
    like 'jnlp.', 'jogamp.' ..

  - Enable registering 'trusted' properties, when caller's cert is 'same'

PropertyAccess: Push down 'isPropertyDefined(final String property, final boolean jnlpAlias)' for trusted properties

The method shall be called by the respective Debug specialization, which registers the trusted property prefix.

Android: New ActivityLauncher (jogamp.android-launcher.apk)

ActivityLauncher provides delegating Activities, allowing the user to:

  - daisy chain custom APK classes and native libraries to the classpath

  - name one custom activity which gets delegated to, the downstream activity

Overview:

  [User:a1] -- (usr-data) --> [Launcher] -> [User:a2] + using [other packages..]

[User APK]   - The user provided APK
[JogAmp APK] - JogAmp APKs

[User:a1]    - The initial user activity, which starts the [Launcher].
               Providing data to [Launcher]: [User:a2], [User APK]
               Resides in [User APK]

[User:a2]    - The actual downstream 'real' activity, spoiled w/ full fledged ClassLoader
               having access to all packages as requested, ie. [User APK], ..
               Resides in [User APK]

[Launcher]   - The launcher activity.
               Gets called by [User:a1].
               Creates a new ClassLoader, daisy chainging all requested APKs.
               Instantiates [User:a2] w/ new ClassLoader.
               Delegates all calls to [User:a2].
               Resides in [JogAmp APK].

Add 'asset' URLConnection; IOUtil uses URLConnection / incr. effeciency; Android ClassLoaderUtil cleanup;

- Add 'asset' URLConnection
  - Please read API doc 'PiggybackURLConnection' and 'AssetURLConnection'

  - Solves generic resource handling where platform locations may differ,
    ie ClassLoader lookup on Android in the 'assets/' subfolder.

  - New Android 'AssetDexClassLoader' uses 'assets/' folder for findResource(..)

  - aapt.signed (our APK ant task)
    - uses 'assets/' folder

    - adds the 'assetsdir' attribute allowing to copy other assets into the APK

- IOUtil uses URLConnection / incr. effeciency
  - using URLConnection on all getResource(..) since URL
    is connected anyways for validation and URLConnection can be used by caller right away

  - String getRelativeOf(URL, String) -> URL getRelativeOf(URL, String)
    - preserves scheme, authority, etc
    - simple parentOf handling, more efficient

  - reusing new 'asset' protocol impl.

- Android ClassLoaderUtil cleanup;
  - Use createClassLoader(..) impl for build-in static jogamp and user APKs,
    which removes code redundancy

Tests: New code path, especially 'assets' are covered by new unit tests, no regressions on Linux.

Adding missing file .. oops

Added adb install files
