Return the actual interpolator of the ViewPropertyAnimator

The implementation of getInterpolator() was always returning null
(probably a quick copy-paste from the default Animator implementation).
This patch fixes the problem by returning the interpolator set by
setInterpolator(TimeInterpolator) or the default one if none has been
set yet.

This patch also avoid creating multiple instances of ValueAnimator in 
order to retrieve some default values.

Fix NullpointerException in MediaMetadataRetriever

According to the API documentation and the ICS implementation
the setDataSource(String) method throws an
IllegalArgumentException if path is null. In JB a
NullpointerException is thrown instead. This fix restores
the earlier behaviour.

Remove incorrect keymapping

Turns out Snakebytes produce all 0s for their vendor / product IDs. This
somehow got the vendor / product ID of an international apple keyboard, which
will break them. Unfortunately, this also means we cannot map Snakebyte
controllers at all.
