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.

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

Reorder the find permission checks. This avoids generating misleading
SELinux denials when a service doesn't exist, or when a service is
prohibited to isolated apps.
The original reason for structuring the code this way is explained
in https://android-review.googlesource.com/#/c/100530/4/cmds/servicemanager/service_manager.c@172
The concern at the time was to avoid leaking a situation where
a caller could probe for the existance of a service. This turns out
to be unnecessary. The same return value is used for both a
permission denied and a service not found. The only side effect
is the generation of an SELinux audit log, which likely won't be
accessible to the calling application.

Call logcat -L to pull any LAST Android logs. If the kernel is not
configured for PSTORE and PSTORE_PMSG, the hopes are the empty
content will pressure vendors to slice up and configure support.

It turns out dump_file is used on a number of /proc and system files.
In one case, the read of a file stalled and caused a bugreport to
hang forever. It's still possible if there is a kernel bug that this
could stall forever, but less likely.
Also, change the return type of nanotime to uint64_t.
Testing:
- Created a named fifo and verified that dump_file fails with a timeout.
- Created a large /data/anr/traces.txt to verify that large files still
dump properly and that the additional NONBLOCK parameter doesn't cause
a problem.
- Created a dummy /data/tombstones/tombstone_00 to verify that the
dump of these files still works.
- Compared a dump using the old dumpstate to the new dumpstate to verify
nothing obviously different.

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.
mpdecision-2172 [000] ...1 1566.665481: regulator_enable: name=krait2

This option doesn't work with the current selinux protections and
doesn't serve much of a purpose. You can get the same results running
this:
