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.

We're now parsing and passing through volume UUIDs sent across the
command socket. The "!" argument value is treated as null, which
means internal storage.

Teach free_cache() and restorecon_data() about building per-volume
paths. Also clean up restorecon_data() by using std::string when
building paths.
Clearer names for path building utility methods, and tests to verify.

Since app data paths can live on expanded storage devices, accept the
target volume UUID when building paths. The null UUID indicates the
default internal storage.
To improve readability, start using std::string in several places,
which throws when allocations fail. For now, perform last-second
sanity checks on incoming path arguments, but we'll eventually want
to check arguments as they come through installd.cpp, instead of
crashing the entire daemon.
Also remove "lib" symlink code from install() and make_user_data(),
since we're no longer supporting /data/app-lib. The framework
already uses linklib() to create the right symlink for the selected
ISA-specific library dir.

This is the minimal change needed to switch it over to C++, which
paves the way for using more robust utilities like std::string.

Apps on expanded storage live at /mnt/expand/<uuid>/app/com.example,
so we need to relax one more directory level.

This patch adds extra logging for the binder version in case the userspace
and kernel versions differ.

service_manager.c gets string.h inherited from
private/android_filesystem_config.h it should
not rely on this in the future. The intent is
to move fs_config function into libcutils and
thus deprecate any need for string.h in this
include file.

Changes to installd:
- dexopt now allows oat_dir param for custom output directory
- Added helper method calculate_oat_file_path for calculating oat file
output location based on oat_dir and apk_path.

Previously odex files were stored alongside the dex location as:
dex location: /foo/bar/base.apk
odex location: /foo/bar/<isa>/base.odex
This changes where odex files are stored, adding an "oat" directory:
dex location: /foo/bar/base.apk
odex location: /foo/bar/oat/<isa>/base.odex
See also the corresponding changes in platform/art and platform/build.
