The following patches allow gst-android to automatically install java classes from plugins if required.

Gstreamer plugins need to install its java classes to /usr/share/gst-android/ndk-build/$(plugin_name) and gstreamer-1.0.mk installs them under src/org/freedesktop/gstreamer/$(plugin_name) to be included at buid time.

This will allow the gstreamer plugins to load the relevant classes using the application class loader.

The last patch declares two global functions to access the application class loader and the application context so the gstreamer plugins will be able to dlsym those functions and use them.
