e22192071d StatsPullerManager not use singleton
This is to be consistent with other patterns such as UidMap.
This also makes unit test simpler.

48944901f7 Fixes statsd returning too much data at once.
We observe a single ConfigMetricsReportList can be greater than the
safe size for the binder transaction buffer since we only check the
size of the current metrics in progress, but we also return the
previous reports stored on disk.

This change will attempt to send another ConfigMetricsReportList
as soon as possible if there's already a report on disk.

Also fixes a bug when trying to trigger data fetch before the client
has registered the corresponding dataFetchOperation.

9def8e3995 Reduce statsd log data size.
1. Hash the strings in metric dimensions.
2. Optimize the timestamp encoding in bucket.
   Use bucket num for full bucket and millis for
   partial bucket.
3. Encode the dimension path per metric and avoid
   deduping it across dimensons.

bd12527c90 Fix uid map to be simpler and fix partial bucket.
The previous scheme captured periodic snapshots for each config with
complex logic that's unnecessary and wasted memory. We actually don't
need to store any snapshots since we just convert the current state
into a snapshot and also include the deltas (change events) since the
previous report until now.

To make the system more robust, we also include up to 100 of the
deleted apps in the uid map.

Also, fix the wiring of the partial buckets so the metric producers
form partial buckets on both app upgrade and removal, but not on
installation of a new app.

Also, we update StatsCompanionService to also include disabled apps.

35045cbc34 Fix uidmap in statsd.
Previously tried an optimization that results in corrupted proto
output. This changes to a safer approach of storing the snapshot data
in memory and only converting to proto output when the
ProtoOutputStream is provided.

Also fixes a security issue when trying to invoke triggerUidSnapshot
since we forgot to use SCS' permissions.

Test: Added a unit-test to verify output of StatsLogProcessor.

4beccbe3de Fix recovery of stats data from previous input while using
ProtoOutputStream

- Specify the length of message to avoid libprotoutil from thinking that
we are trying to write bool
- We only attach the previous dump file to the upload file where config
key matches
- Store ConfigMetricsReport (instead of ConfigMetricsReportList) onto
disk
- Stop use stack after scope in StorageManager
- Migrate UidMap to use ProtoOutputStream and renaming variables to
prevent confusion

f384b90049 Removes stats_log proto from uid map in statsd.
We don't need to parse the proto of uid map, so we use the
ProtoOutputStreame class to generate the binary form of the proto
output that's needed for parsing the uid map data.

Test: Verified unit-tests still pass.

cfc311d2f0 Statsd always includes snapshot of uid map.
Statsd will contain at least one snapshot of the uid map. The
previous design was not very robust in case a snapshot was missing.

Also fixes subtle bug with updating the isolated uid mapping since
this should always be kept up to date even if there are no metrics
being used (since metrics may be added later after the isolated uid
was created).

Test: Checked that unit-tests pass on marlin-eng.

3accca05dd Add major version code to platform.
It turns the version code into almost a 64-bit integer, with the
new major part being the upper 32 bits.

The only tricky part about this is the backup manager, since it
stored 32-bit version codes in its backup data sets.  This is dealt
with by, when the major version code is not 0, writing MIN_INT as
the version code and following that by the full long version code,
which we can detect when reading.  Note that this makes backup sets
containing apps with major version codes incompatible with older
versions of the platform.

c136f45aee Adds guardrail for memory usage for statsd uid map.
Checks if current memory usage of uid map is above a configured limit
and if so, we start deleting snapshots. If there are no more
snapshots, we begin deleting two of the deltas. Also records stats
in the guardrail StatsdStats. Also fixes an edge case where a config
is added after the snapshots are added. We request a snapshot of all
installed uid's at that moment. Finally, adds the uid map memory size
when determining if we should send a broadcast to trigger collection.

Test: Added unit-tests and check they pass on marlin.

80235403d2 statsd: parse the new format of stats log
+ Changed how we construct LogEvent, now it's based on the context from log_msg
  without making a copy of the list.

+ All stats logs now have the same event tag, the atom id is the first elem in the log.

21582961d7 Tracks isolated uid's and their parent uid.
We push events from BatteryStatsImpl if an isolated uid is added or
removed and we have a custom rule in statsd to use these events to
update our uid map. In the future, we need to use this map to
convert all incoming uid's to their host uid.

Test: Added unit-test to UidMap_test.

d689689891 Updates uidmap to update snapshots and upload.
We send a snapshot of all installed apps with their uids every time
a user is added or removed and when statsd is started.
We keep track of the latest timestamp when a config key has retrieved
the UID map data. This allows us to remove older data when we're
guaranteed that all config sources have retrieved the old data.

Test: Added more unit tests to UidMap_test and passed on marlin-eng.

9fc9edf95a 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.

de70169109 UID mapping to provide app name and version.
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.
