We want to create the classloader for the WebView in advance in the
zygote so that it can preload Java and native code for its children, but
the zygote can't talk to the package manager (so doesn't have a
PackageInfo for the APK) and also doesn't have an ActivityThread, so
constructing a LoadedApk is difficult.
Instead, we use the fact that ApplicationLoaders contains a
process-global cache of classloaders for APKs, and prepopulate a cache
entry without constructing a LoadedApk. This requires making
ApplicationLoaders public. To calculate the correct library paths from
the information the zygote has, we reuse the logic in LoadedApk (which
is already public, and just needs a small change to allow a null
ActivityThread when checking for instrumentation).
The other parameters for classloader creation (target SDK, bundled app,
etc) are hardcoded to usable values for the WebView's case. WebView
never needs to use any system libraries that aren't public so claiming
it's not bundled is fine even when that isn't actually true, and WebView
will always target the current platform API level.
Once the classloader is created, look up the factory class and call
preloadInZygote on it to give it a chance to preload the native library
and do other shared initialisation.

Avoid the allocation of an unneeded string. With more than 4000
classes being preloaded, this adds up.

Added a service that listens whether emergency affordances
are necessary.
If the they are needed, it adds an option to the
global actions dialog that directly launches the
emergency call and also adds a long-press listener
to the keyguard emergency button.
Test: adb shell settings put global force_emergency_affordance 1 && adb shell settings put global emergency_affordance_number 111112

There is no functional change. This is to support adding new types of zygotes
that all operate using the same protocol.

This is a non-functional change that separates out functionality
that should be shared between the system zygote and the WebView
zygote from that which is system zygote specific.
* Move MethodAndArgsCaller to Zygote.
* Split out server socket functions into ZygoteServer.
* Add a new (stub, for now) WebViewZygoteInit class.

This adds a new init-spawned daemon, webview_zygote, that starts a JVM and
acts as a zygote process for WebView isolated_app services.

The limit is MAX_WAKELOCKS_PER_UID+1, since OverflowArrayMap
will add one more to contain the overflow.

Add the FLAG_RECEIVER_FOREGROUND flag to the broadcast intent
triggered by hardware key.
This prevents the framework from delaying the delivery of the
intent to its recipients, and improves the response for hardware
key event under heavy load on the system.

Add java.library.path to list of permitted paths

* changes:
Fixed a bug where the dimmed background could be invisible
Fixed an issue where the inline controls where not usable
Added Emergency affordance feature
Sometimes, makeSingleLayout() can be invoked before layout direction is resolved.
When not resolved, it indents in LTR layout although it should be RTL.
So, to guarantee the exact indenting, we should re-build the text layout
when the layout direction is changed.
Test: manual - Test BigTextStyle notifications with LargeIcon under RTL configurations.
