Statsd cpu optimizaton
- cache the changed dimensions in condition tracker.
- avoid query condition wizard when unnecessary.
- avoid copy dimension keys in condition key generation.
Test: statsd tests.

Add StateTracker.
StateTracker is a special condition tracker that's based on a state atom.
State atoms are annotated in atoms.proto.
The rules for StateTracker:
1. must not have "stop". must have "dimension"
2. must be based on a state atom.
3. it must have the all primary fields and the exclusive state field in its dimension.
For example UidProcessStateTracker, will have output dimension {uid, state}.
Test: unit tests added.

Statsd CPU optimization.
The key change is to revamp how we parse/store/match a log event, especially how we match repeated
field and attribution nodes, and how we construct dimensions and compare them.
+ We use a integer to encode the field of a log element. And also encode the FieldMatcher into an
integer and a bit mask. The log matching becomes 2 integer operations.
+ Dimension is stored as encoded field and value pair. Checking if 2 dimensions are equal is then
becoming checking if the underlying integers are equal. The integers are stored contiguously
in memory, so it's much faster than previous tree structure.
Start review from FieldValue.h
Test: statsd_test + new unit tests

Support dimension in condition in metric producers.
Test: added e2e tests for count/duration metrics sliced by fields in condition and with/without links.

1/ Support nested message and repeated fields in statsd.
2/ Filter gauge fields by FieldMatcher.
3/ Wire up wakelock attribution chain.
4/ e2e test: wakelock duration metric with aggregated predicate dimensions.
5/ e2e test: count metric with multiple metric condition links for 2 predicates and 1 non-sliced predicate.
Test: statsd unit test passed.

Add support for dimension, and link with condition and added DurationMetric
Now we support following metrics:
<Duration> of [app holding a wake lock], while [*this app*] is [in background] [AND] [screen is off]
[Slice] the output by [app name, wake lock name], with bucket size [30sec]
+ Also added onDumpReport() api in MetricsManager, it can be called from client to fetch the data from
statsd
+ Also added command line tool to dump the StatsLogReport from all metrics for debugging.
+ Synced proto from google3. with a pending cl (cr/172359050)
TODO: We need to add tons of tests to test the Metrics. I will work on it after this CL so people
can be unblocked.
I locally test the duration metric with wake lock with an app that generates StatsLog events.
Test: statsd_test
and manual test, and run:
adb shell cmd stats dump-report
We have a default config, which contains a metrics to count PROCESS_START event sliced by
package name.
