(cherry picked from commit 5d7d777fa6)
We used the system proterties as a shared memory mechanism
to propagate information to local settings caches when the
content has changed and the cache should be cleared. The
system properties are unfortunately updated asynchronously
leading to cases where clients may read stale data.
This change adds a simple int array data structure backed
by shared memory which guarantees individual values are
atomically read and updated without memory tear. Multi-
index opearations are not synchronized between each other.
The settings provider is using the new data structure to
propagate the settings generation which drives when caches
are purged.
We have a single memory array keeping the generation for
different settings tables per user. Since memory array is
not a compact data structure and the user space exceeds
the memory array size we use an in-memory map from keys
to indices in the memory array where the generation id of
a key is stored. A key is derived by the setting type in
the 4 most significant bits and the user id in the 28 least
significant bits.
The mapping from a key to an index is cleared if the user is
removed and the corresponding index in the memory arry is
reset to make it available for other users. The size of the
memory array is derived from the max user count that can be
created at the same time.

Adding the Context hub service. This is the service that exposes
the context hub HAL to the system. The API exposed is a System API.

Displays list of problems linker encountered with app's
native code including
1. Unauthorized access to private platform libraries.
2. Text relocations
3. Invalid DT_NEEDED entires
This change is intended only for preview/beta releases and to
be reverted before the first release build.

With this change ApplicationLoaders.getClassLoader()
creates linker-namespace for the classloader at the
construction time. Before this change the namespace
was created on first load of a jni library.
With this change we ensure that every classloader
has initialized namespace associated with it.
As an additional advantage we now can avoid storing
namespace-specific fields in the classloaders.

Add HardwarePropertiesManagerService which call native methods to
get CPU, GPU, battery temperatures, CPU usage info, fan speeds.
Restrict hardware properties retrieval only for device and profile
owners.

This CL runs VectorDrawable animation on RenderThread. The changes in this CL
include:
- Convert all the animators in AnimatorSet for AVD into a set of RenderNodeAnimators.
- Hook up the new animators with RenderThread
- Add drawOp in RecordingCanvas for drawing VD so that during the animation
on RenderThread, all the property changes on VD can be reflected on the screen.
TODO:
- Implement reverse and reset for AVD.

Add serive "hardwareproperties" and methods getDeviceTemperatures,
getCpuUsages and getFanSpeeds to retrieve hardware properties:
device temperatures (CPU, GPU and battery), CPU usages and fan speeds.
This is a public API.

The background compilation service will trigger a profile based
compilation instead of a full one. If no profile information is
available the compilation is skipped (see installd).
Note that the end decision whether or not to compile a package is taken
by dext2oat. We can't make the decision here because this service runs
under system server which cannot read app's profile data.

- Refactored VPathRenderer & VectorDrawableState
- Moved all the VD rendering into native
- Set up hooks for VD's property changes in JNI for animated VD
TODO: JNI calls can be further reduced when we convert the animation
in AVD to use RenderNodeAnimator, in which case animation will be
driven from native and therefore most of the JNI hooks for changing
VD's properties during animation will no longer be needed.

When starting the runtime from app_process, we only pass JDWP options
if starting zygote. It prevents from opening a JDWP connection in
non-zygote programs while Android apps (forked from zygote) remain
debuggable.
