niko dcd810d013 Renamed all android.hardware.IMedia* strings to android.media.IMedia* 
The android.hardware.ICamera string have not been changed (but is looks
like the camera service and client one should undergo the same procedure)

The implementation of the interface must provide a unique string for
it's interface name. Currently all these strings in the media framework
start with 'android.hardware' when it should really be 'android.media',
the interface token has nothing to do with hardware.
