We are currently dumping invalid data for pulled metrics. Pulled metrics
require a new pull when flushing a bucket. We should either do another
pull or invalidate the previous bucket.
There are cases where we cannot afford to do another pull, e.g. statsd
being killed. If we do not have enough time, we'll just invalidte the
bucket to make sure we have correct data.

Modifies statsd unit tests to also assert the active configs changed
broadcast is called at the right time with the right configs. One case
has one config with multiple activation signals, while the other has
multiple configs that are activated at the same time with one signal.
Test: this is the test

Statsd now sends active configs changed broadcasts when needed per uid.
Also made an adb command to help debug.

After erasing the statsd data, allow statsd to have an empty report, or
even a report with a non-empty metrics wrapper, as long as it doesn't
have any of the former count metrics in it.

Change-Id: I525c61aea97a185df8916e4c1b4c4118493ed780
Adds a tool for local usage of statsd. The tool can:
-upload a config from a file
-get the report data from statsd
Both the config and the report can be either in binary or human-readable
format, as specified.
Usage:
make statsd_localdrive
./out/host/linux-x86/bin/statsd_localdrive
Also, adds the ability to specify whether dump-report should also erase
the data when it returns it. A test for this is added.

* Creates an incident section for statsd data.
* Allows dump to output statsd data, in proto format.
* Hooks up two statsd outputs to bugreports:
-statsd report data in proto format
-statsd metadata (statsdstats) in text format
The incident section does not import stats_log.proto because that turns
out to be extremely difficult: stats_log.proto imports atoms.proto,
which imports more things and is enormous and causes all sorts of
problems. atoms.proto was purposefully never compiled in AOSP, so to
retain that feature, the incident section uses 'bytes' instead of an
actual message. Since this isn't ever read in AOSP (other than testing),
this should be fine.

Test: unit test
Reports written to disk don't contain the strings used, which will
make this report unusable if there are strings that don't show up
again. We should always include the strings, so this option is
removed entirely.
Also, we hard-coded the wrong number of fields when pulling
ModemActivityInfo. There are actually 10 fields, not 6.

We notice devices uploading a bunch of bytes for the uidmap even if
the device is running an empty config, so there are no actual metrics
to report. This hardcodes some logic to skip the inclusion of the
uidmap if there are exactly 0 metrics.

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.

BUG: b/77813755
When statsd reconnects to logd, statsd will read all logs from buffer again. To prevent us from
reprocessing old events, we do the following:
1. At any given moment, record the largest timestamp(T_max) and last timestamp (check point) that
we've seen before.
2. When reconnection happens, we look for the check point until we see a new log with a timestamp
larger than T_max.
-> If we found the CP, resume after the CP. Success
-> If we can't find CP, there is definitely log loss. We reset all configs.
Note:
1. Logd has an API to read logs after a certain timestamp. But this api is vulnerable to
time changes from Settings. So we cannot rely on it.
2. If logd inserts a new log (with older timestamp) before CP, we cannot detect it. It's not
possible to detect it without record all timestamps we have seen.

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.

It's tricky to determine the source of the metrics on a device
currently since we can take the union of multiple configs and send
only one giant statsd_config into statsd. We will use the int64 field
to track the sub config id's and the int32 field to track the version
for each sub config, but the fields are named more generically as
annotations.
The annotations are available in both the reports and metadata.
Test: Check that all unit-tests pass on marlin-eng

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.

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.

We use one alarm clock for all pulled atoms.
If metrics from different configs are not aligned,
the clock will be set to repeat at higher and higher
frequency, and consume a lot of battery.
Current implementation assumes a 5min minimum bucket
size. New metric start time is set to be aligned to
the start time of statsd in the next 5min.
So it will ignore events up to 5min.

The exception is EventMetricProducer. Each EventMetricProducer will still have a ProtoOutputStream
Because LogEvent comes as a fixed 4K, it's more memory efficient to have an 8k ProtoOutputStream for
storing the events.

Since there is a separate guardrail for memory used by uid map, we
no longer add the memory from uid map with the memory per each
config's metrics. We also prevent the byte size check from happening
too frequently. In order to mock the MetricsManager, we refactor
some of the existing methods.
