reorganize SoundPool and JetPlayer code.
Reorganize SoundPool and JetPlayer code to be ready for the creation of libmedia_native. Split SoundPool between libsoundpool (JNI) and libmedia(sound pool implementation). Remove dependencies on nativehelper/jni.h from JetPlayer. Change-Id: I130c6014173b714329929dd82c5dfb70b757a610
