+ Add log source whitelist in StatsdConfig
+ Some changes in UidMap API. Listener needs to be wp instead of sp.
+ Update dogfood app config to have log source
+ Increase the stats service thread pool size to 10 (9+1).
TODO: add unit tests(b/70805664). This unit test takes some time to write.
Test: statsd_test & manual

- 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.

The UID map is updated by StatsCompanionService, which listens to broadcast
updates indicating that an app was updated/installed or removed. Also,
the entire map is updated when statsd first connects to the companion
service. Also, there is a way for metrics producers to subscribe to
updates, so that they can know when an app was upgraded.
Test: Created new unit-test for mapping and manually tested for install
and remove. Did not manually test the app upgrade.

Added .clang-format, because there isn't an official .clang-format file for Android framework code.
before we upload changes, do:
clang-format -style=file -i [file list]
to format the files that you touched.
Test: formatting only. NO code changes.

Statsd code now lives in android::os::statsd namespace. Existing files
are largely modified to follow this convention.
Exception: parse_util, since it seems a bit different.
Test: code compiles and existing statsd_tests still pass

If statsd or statsdcompanion crashes, or if one loads
before the other, the other will be able to accomodate.
When statsd loads, it will attempt to tell statscompanion that it's
alive, and then get on to its business, while assuming that
statscompanion is not alive. Only when statscompanion tells statsd
that it is alive, statsd will then start to use it.
When statscompanion loads, it will attempt to tell statsd that it's
alive and then do nothing (since it has nothing to do). When statsd
tells statscompanion that statsd is alive, statscompanion will respond,
telling statsd that it is alive and, if that binder call returns, will
get to work.
This way, if statsd loads first, it can work unobstructed until
statscompanion informs statsd that it is alive, at which point they
shake hands and work. Conversely, if statscompanion loads first, it will
do nothing until statsd contacts it, at which point they will shake
hands and work.

must be in serialized binary format. Also fixes small issue
in build rule related to proto lib.
Test: Manually tested that ADB command works without crashing.

+ The DropboxWriter keeps data in cache, and flush to files once the
size exceeds the maximum value.
+ Different components should create their owner DropboxWriter with
different tags, e.g., anomly detection, experiment metrics, etc.
+ Copied stats_log related protos from g3
Test: run statsd, and adb shell dumpsys dropbox
Will add unit tests.

It doesn't start yet by default. When you start it manually, it sets
itself up as a binder system service and starts a thread to read the
event log.
Test: Run statsd, observe output. also run stats_test
