Now that scoped_ptr is just a type alias to unique_ptr, there is no
longer a need to convert between the two by using .release() and
constructing the other with a raw pointer.

The unittest was creating a brillo::Daemon in a smart pointer and then
resetting it to a newly created different brillo::Daemon instance. This
creates two brillo::Daemon instances for a short period of time, which
both setup global context (the default message loop).
This patch fixes this situation by deleting the service before creating
a new one.

Without this setting, arguments passed to a function can be packed in
more than one line, with more than one argument per line.
For example, the following code will be formated as this without the
BinPackArguments:
CallMyFunction(
with_more_than_one, argument_per_line,
event_they_dont_fit_in_a_single_line);
On the other hand, with BinPackArguments: false, that code will be
split in:
CallMyFunction(
with_more_than_one,
argument_per_line,
event_they_dont_fit_in_a_single_line);
or all the arguments in the same line if they all fit.

This CL adds two more checks:
* When populating a closed log with the metadata, make sure the
SystemProfileSetter is not null.
* When using the update engine client library, check if the update
engine client object was created correctly. The returning object can
be null if update engine's binder service is not running.

When metricsd receives a SIGTERM signal (on system shutdown for
example), save the metrics to disk before exiting.

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.

correctly.

metricsd should shutdown cleanly when receiving a TERM signal:
* stop the binder watcher.
* wait for the thread to quit.
* Exit cleanly.
Note: This is not directly used as we don't send SIGTERM on shutdown or
when stopping services yet.

This fixes the documentation for UploadService and the README file:
* stop mentioning Chrome OS as we forked the code.
* update the histogram declaration workflow. It is not tied to Chrome's
histograms.xml file anymore.
* update the architecture explanation of metricsd. We split
metrics_daemon into two daemons and are now using binder to log
metrics.
* convert README to markdown to make it prettier when viewed in gitiles.

No longer needed to trampoline between RTTI and non-RTTI compiles.
Move the service impl from libmetricscollector service to the
metrics_collector executable, now that RTTI is no longer used (and the impl
is not used by binder clients).

* Move service registration and binder watcher to metrics_collector main.
* Compile libmetricscollectorservice with clang just because.

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.

$ metrics_client -d

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.
