This allows us to:
1. Rank contacts and only add the top N names to the keyboard LM.
2. Avoid adding duplicate names.

Note: The affinity calcualuation is limited by the fact that some apps
currently do not update the TIMES_CONTACTED counter. To better handle
this case, the new measure also takes into account whether or not a
name is in the visible contacts group.

There should be 1 executor each for static and dynamic language models.
This prevents too many dynamic LM updates from running in parallel,
competing for resources.

Break contacts binary dictionary into two parts
- one that talks to contacts content provider and maintains
  local state. Includes a manager class and a content observer
- other one that just manages the dict code.
