android.os.UpdateEngine.verifyPayloadMetadata() allows a system updater
to verify a payload can be safely applied, by using its payload metadata
(usually a few hundred KiB only or even less). This would be useful in
improving update UX, since the updater can be smarter to avoid
installing an update that would fail to apply, or to fall back from an
incremental to full payload.

Previously, statsd would inform interested listeners that it's time
to collect data via a protected broadcast. However, the preferred
solution is to pass a PendingIntent via a separate setter. Whenever
statsd wants the listener to call getData, StatsCompanionService
will trigger the pending intent.
Test: Tested in marlin-eng that functionality works as expected with
dogfood app.

Now requires permission if targeting P.
Note that this is a separate permission from the existing one
that is required for instant apps to use foreground services. The
reason for this is that their semantics are different (the instant
apps permission is associated with an app op for control over what
the app is allowed, while the regular app permission is just a
normal permission that is always granted and only there for
auditing of apps), and there are probably going to be cases where
a developer will want to use a foreground service in the full
version of their app but not as an instant app.

The majority of Manager-style classes already use Context.getUserId()
when making calls into the OS, so clean up the remaining callers to
unify behind this strategy.
This gives @SystemApi developers a nice clean interface to interact
across user boundaries, instead of manually adding "AsUser" or
"ForUser" method variants, which would quickly become unsustainable.

There are several places across the OS where Java code is simply
copying data between two points, which requires bringing that data
out into userspace before going back into the kernel. (That's pretty
lame.) The patches for the recent Meltdown/Spectre security issues
have made this overhead even worse, so it's finally time to move this
copying directly into the kernel.
This change adds a couple new FileUtils.copy() methods which inspect
the given streams/FDs, and attempt to do as much optimization as
possible before falling back to a slower userspace-based copy.
Benchmarks are showing typical improvements of 44% for 32KB files,
50% for 32MB files, and 35% for 32MB pipes.
Plenty of tests are included, and there's a simple kill-switch that
can be used to enable/disable the feature if it starts causing any
trouble. (A future CL will enable the optimizations.)

Tuned rates that we collect PSS, to reduce how much we do
that heavy operation. Added a new way to determine
whether a process has changed to a state for the
"first" time -- now this is when it has gone to that
state for the first time since it was in a lower state.
This will reduce the amount of time we consider a
process to be first to only when it has previously
gone into a higher state than it had before.
Keep track of more fine-grained information about why we
collect a PSS sample (not just internal, but for a single
process, all processes because of a mem state change, all
processes because of a poll).
Started collecting RSS in various places, so we can start
looking at that w.r.t. PSS and see about transitioning to
it is a new primary metric.
Added logging for many of the places where the system
writes its configuration files, so we can more easily
see any bad behavior going on in those areas.
Added some currently disabled code to read smaps directly
instead of using fgets(). Probably won't help, but want
tot test.

Created an enums.proto that contains the device idle modes,
which is referenced by batterystats.
Note that, currently, batterystats is the origin of these
constants in the java code, and I have kept that as is.
Thus, batterystats references the enum.
Nevertheless, because the actual control of device idle
mode is DeviceIdleController.java, where these constants
will likely one day be moved, I have put the constants
in server/enums.proto (since DeviceIdleController is
in server, not os like BatteryStats).
