Every now and then (5 minutes by default), the uploader will persist the
current metrics to disk to avoid losing them in case we exit
unexpectedly (reboot or crash).
When starting up, metricsd will load the previously saved log and resume
the metrics collection from there.
Bug: 25670584
Test: Unit tests.
Test: manual: restart metricsd. The saved log is detected and parsed
correctly.
Test: manual: Send a sample to metricsd, send SIGTERM to metricsd, the
log is saved to disk, metricsd restarts and picks up the log where it
left.

This CL converts metricsd, libmetrics and metrics_collector to use
Binder to pass metrics samples.

Instead of using a single directory for both the internal data of
metricsd and metrics_collector and the shared files (metrics samples log
file and the metrics enabled file), we should use separate directory to
allow for a finer access control.
The new structure will be:
* /data/misc/metrics for the files accessible to all daemons reporting
metrics, metricsd and metrics_collector.
* /data/misc/metricsd for the private files of metricsd.
* /data/misc/metrics_collector for the private files of
metrics_collector.
Bug: 25886951
Test: Unit tests.
Test: Manual: metricsd and metrics_collector run without errors.

When the model manifest id is defined in weave, report it.
Bug: 25386505
Test: the model manifest id is uploaded when defined.
Test: If weaved.conf is not defined, metricsd uploads the default value.

This stops relying on system properties to provide build time
configuration.
Product version and id will be stored in /etc/os-release.d.
Channel will be pulled from update engine.

We decided to change the name of this identifier to "product id", the
system property where it is stored will also be named
ro.product.product_id.

If the metrics server is unreachable, we may need to resend a metrics
report later. Instead of keeping the staged report in memory, save it to
disk to avoid loosing data if the system restarts or crashes.

TEST: unit tests.

Instead of passing different filenames around, only rely on the metrics
directory and infer the filepath from it. This makes testing easier.

Instead of using /etc/lsb-release to store the version, channel and
build_target_id, use the Android system properties.

This makes the import path less confusing:
* metrics/metrics_library.h is imported from the exported headers.
* metricsd/* for includes by the metrics daemon itself.
