Clean up how we handle configurations, and other assorted cleanup
- Add a ConfigManager class that tracks the configurations
that have been passed to us. Configurations are now
tracked by tuples of (uid,tag), where the tag is an
app-defined string, in case a single uid has multiple
configurations.
- Move all of the initialization into StatsService.
- Get rid of the ability to have multiple LogListeners. Raw
events are now pushed directly into StatsService, which
can distribute them to the interested parties (and will
eventually be able to do the proper locking).
- Add Log.h, which sets our LOG_TAG correctly.
- Move some of the related files that I expect will grow some
into their own subdirectories.
Test: statsd_test
Test: adb shell cmd stats config ...
Test: adb shell dumpsys stats
