Switch user crash event notification from D-Bus to this Binder service.
Add a trampoline as a go-between for the -frtti and -fno-rtti sources.
Add MetricsCollectorServiceClient for crash_reporter to use, hiding the

Assert abort metricsd if binder service registration fails.
If the addService() call fails (for reasons that at least include an SELinux
policy denial), the call to joinThreadPool() apparently processes a stale
pending weak dereference that triggers an abort on a probable double-free:
F libc : Invalid address 0xbe8bfa30 passed to free: value not allocated
F libc : Fatal signal 6 (SIGABRT), code -6 in tid 609 (metricsd)
Since metricsd is severely hobbled if registration fails, abort and see if
things work better the next time. If not, the crash loop will hopefully
attract attention to the problem.

This CL adds a dump command to metrics_client that will dump the
histograms, aggregated by metricsd since it started, in a human readable
format.
This is useful for developers to ensure that their code uses libmetrics
correctly and the reported values are correct.
Sample output (redacted to fit the commit message):
$ metrics_client -d
Histogram: hello recorded 5 samples, average = 54.8 (flags = 0x1)
0 ...
9 --------O (1 = 20.0%) {0.0%}
16 O (0 = 0.0%) {20.0%}
29 --------O (1 = 20.0%) {20.0%}
54 ------------------------O (3 = 60.0%) {40.0%}
100 O (0 = 0.0%) {100.0%}

Bug: 25817310
Test: * Send a histogram with metrics_client.
* `metrics_client -d` shows it.

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.

This CL splits metrics_daemon into two independent daemons: metricsd and
metrics_collector.
* metricsd will be responsible for reading the metrics from disk and
periodically uploading them to the server.
* metrics_collector will be responsible for gathering generic metrics
from the system and managing the weave state for metrics.
This refactoring is necessary to prepare the migration of metricsd to
log over binder.
Bug: 25670908
Test: Unit tests.
Test: manual: both daemons run. Metrics are logged, uploaded and the
weave interaction works.

We cached the enabled status for metrics as a static field in the
metrics library. This field is not reset in between tests which treats
the metrics as enabled if they were enabled previously.

Also enabled the metrics in upload_service_test.cc after verifying that
the test failed consistently.

This fixes three things:
* name of the metrics: the metrics does not represent the daily use.
* arithmetic error: we collect the use time in seconds so no need to
divide by 1000 to get seconds.

resetting the counters.
