Provide more extensive listener features.

Browse Source 
This enables listeners to be notified of not only value updates, but also flag
changes and deletions by using a bitmask to specify what notifications are
desired.  The old API (which only provided a new/not new) flag is still
supported.  This also subsumes the feature to listen to local changes (that's
one of the bitmask options).
