Basic plumbing to retrieve metadata from the native player.
IMediaPlayer.h
Added a getMetadata method that mirrors the on in MediaPlayer.java.
MediaPlayer.java
Added a native method to get the metadata from the native player.
Parse the parcel into a Metadata object.
Metadata.java
Added a stub to parse the Parcel returned by the native player into
a set of metadata.
android_media_MediaPlayer.cpp
JNI call to forward the getMetadata call.
MediaPlayerService.cpp
MediaPlayerService::Client implements the new getMetadata method added in IMediaPlayer.h
