The logic of where refractory period enforcement was moved out of the
anomaly tracker and into the metric's predictAnomalyTimestamp. It was
done for ORING, but not for MAX. This fixes MAX.

Mostly to add test to assure the corner cases are covered.
One minor logic change is if two true conditions happen, in the case
when following happen:
(bucket boundary1) -> (condition false) -> (condition true) -> (pull
triggered for the boundary1)
Previously we take the latest. Now we skip the late boundary pull.

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.

Statsd clients may want to set an empty config temporarily, so it's
more convenient to allow them to set an empty config instead of
having to use the removeConfig and then having to remember to call
StatsManager#setDataFetchOperation.
Test: Added unit-tests and check they pass on marlin-eng.

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

Past buckets had a field mBucketNum, storing the
"bucket number" they represented. Currently, the concept
of bucket number is used by Anomaly Detection (although this
may not be necessary), but these stored values are not used at all,
so removing them will save RAM.

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.

+ This is useful when we want to build Anomaly detection on wakelocks, but want to whitelist

in such a config.

+ A state change atom can have one exclusive state field, and any
number of primary key fields.
When there is primary key in the atom, it means the state belongs to the primary key.
For example,
message UidProcessStateChanged {
optional int32 uid = 1 [(stateFieldOption).option = PRIMARY];
optional android.app.ProcessStateEnum state = 2 [(stateFieldOption).option = EXCLUSIVE];
}
When there is no primary key fields in the atom, the state is global.
For example,
message ScreenStateChanged {
optional android.view.DisplayStateEnum state = 1 [(stateFieldOption).option = EXCLUSIVE];
}
+ The annotation is consumed by stats_log_api_gen to generate a static map from the state
atoms to its primary fields, and exclusive fields
+ stats_log.proto is splitted into 2 proto files, because statsd needs proto lite, and c++
lite proto library cannot properly ignore the field options which requires full proto.
This CL doesn't change any logic in the statsd yet. A separate CL will use the field option
information to correctly track the state.
Test: added unit tests in stats_log_api_gen_test. and statsd_test pases.

Statsd supports anomaly detection for max duration, which is
conceptually like asking for an anomaly on the current duration.
There was a bug previously in the logic for max duration since we
recorded a duration every time a dimension went into pause. Now, we
only record a max duration when the dimension goes into stop.
When a dimension inside the MaxDurationTracker leaves the started
state, we need to check if we still need to keep an anomaly alarm
set. It's possible that we just immediately set an alarm with the
same timestamp as what was just deleted.
Test: Added some unit-tests and tested on marlin-eng.

Renames the apphook atom to be more descriptive. Renames time
suffixes to match more clear convention (ms and msec are ambiguous).
Adds a field to CPU active time that's required for the metrics

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

Statsd will create partial buckets in all metrics producers when an
app is upgraded so that we can separate metrics between different
versions of an app. By looking at the uid map changes, we can tell
which app versions belong to a bucket; for metrics that are not
affected by an app version, we can instead join the buckets together.
To simplify the logic, the ends of the full buckets are always
aligned to when the metric producers were created. These boundaries
are computed on the fly by using the bucket number and the metric
producers' start times.
We keep the anomaly trackers to only be given full buckets; we buffer
the partial buckets within each metric producer.
Duration metric's MAX_SPARSE is fixed to be implemented as such. In
addition, after further discussion, we find anomaly detection on
MAX_SPARSE to be unnecessary, so this functionality is removed.
Test: Unit-tests added and modified, passed on marlin-eng.
