Implemented the metadata changed notification filters.
IMediaPlayer: new setMetadataFilter method so set a filter (2 lists of allowed and blocked metadata type) serialized in a Parcel. MediaPlayer.java/android_media_MediaPlayer.cpp/mediaplayer.cpp new setMetadataFilter that passes the filter down to the MediaPlayerService's binder interface. MediaPlayerService.cpp The Client inner class holds the allowed and blocked metadata types. These are in 2 vectors that get populated in the setMetadataFilter. A new shourldDropMetadata method returns true if a type of metadata should be dropped according to the filters. The notify method in run the metadata update notifications thru the filter and possibly drop them.
