Devices like dory get slammed when bugreports are taken and can't
compress all the raft logs in the current 5min timeout. Our dogfooders
spend their precious time getting us bugreports and then we can't act
on them because we have broken raft logs. :(
This change bumps up the timeout in the hopes that we can get complete
logs from even our slowest devices.

Do not fall back to dalvik.vm.dex2oat-threads if
dalvik.vm.boot-dex2oat-threads is not set. Also do not ever use
the value of dalvik.vm.image-dex2oat-threads. Instead use the
default behavior of dex2oat in that situation.

Expect the boot status explicitly as a parameter so that we do not
have to rely on dev.bootcomplete, which isn't meaningfully set
when the device needs the decryption screen on boot.

Check dev.bootcomplete in dex2oat(). Use the information for
two changes.
Only switch to the background when we're post bootcomplete.
This will ensure better utilization after upgrades.
Add a second dex2oat-threads property that is used pre
bootcomplete. A separation of these phases allows using less
cores when the device is up, freeing up resources for other
purposes, e.g., avoid jank. The precedence during boot is the
boot property, or the image property if the former doesn't
exist, or the default property as a fallback.

Also, move NetworkDiagnostics between the two runs of getting the
wifi counters, so we can see the effect on the counters of
sending our probe packets.

This maps a monotonic timestamp to the
corresponding real-time timestamp, which
can be used to match up the traces with
other logs that use real-time.
Also write clock_sync records first instead of at
the end, to avoid not being to write it due to the
buffer being full.

- For those that are proud to call themselves logspam police
- Every time someone declares that something is too chatty, or that
they lost their logs because they were declared too chatty and
their associated logs were aggresively pruned we generally
ask them to report the logger statistics to pinpoint what software
product that is the elephant in the room.
- Every time we want to spawn a new 'stop being so spammy' bug spawned
off a bugreport collected for another purpose, we *wish* we had the
logger statistics to help add gravitas to the claim that some piece
of software is the top, or near the top, polluter.

restorecon_data already iterates across all found users internally,
so we don't need to call it for each UID moved. In fact, this was a
bug that caused data for the owner to be relabeled when moving apps
back to internal storage.

App movement now has three distinct stages: copying, scanning, and
cleanup. Previously, a battery pull late in the move process would
end up with packages.xml pointing at the old location which had been
torn down. Now, we update packages.xml to point at the new location
as the "source of truth" before we start deleting the old location.

Discover the logcat buffer size, divide by the worst storage
speed in kb/s, and multiply by ten to estimate the timeout in
ms for each named buffer. If that value is less than 20 seconds,
then select 20 seconds. Apply this to each logcat request.

Given a pair of absolute paths {from_path, to_path} , check that
they are both valid apk subpaths (eg. /data/app/package/foo) and
link(2) to_path to from_path. This is required by staged installs,
where we link existing apks and oat files to their staging location.

The selinux_status_*() interfaces require calling selinux_status_open()
first. Since this was not being called by servicemanager, the
selinux_status_updated() call was always failing and servicemanager
was not reloading service_contexts upon a policy reload.

Cherry-pick of c2c6ecd119 from AOSP
Tracing the state of the voltage and current regulators enables a developer
to attribute power consumption measurements to specific perhipherals and
cores. Unlike other indirect methods of tracing when peripherals and cores
are toggled, the regulator ftrace event indicates the exact point in time
when the kernel switches on or off the device. For example, in the following
trace, a developer can see exactly when the krait2 core starts receiving
power, and and when the voltage is set for voltage scaling.

We now move code under /data/app/com.example when a complete move
is requested. This really only works for new cluster-style installs
that also have native libraries and OAT contained inside.
Teach measuring code about cluster-style installs when measuring
app footprint. Also offer to measure private data space for all
users.

New "mvuserdata" command will move all private app data from one
volume UUID to another. It leverages the existing "cp" toybox
command to do the heavy lifting for all known users, preserving
details like timestamps and permissions. It invokes restorecon()
to correctly label the new location when the copy is finished.
Changes installd to no longer drop capabilities, so we run as root
again. This also allows us to exec "cp" with CAP_DAC_OVERRIDE and
CAP_FOWNER still in effect.
