Reads all thread CPU usage for the current process. This traverses
"/proc/self/task/*/time_in_state" to gather the thread ID and CPU usage
of each child thread. Process name, thread name, and UID are also read from
"/proc" for interpretable data.

To support teamfooding of the new storage privacy features coming
in Q, we need apps to request new AUDIO/VIDEO/IMAGES permissions, but
most of those apps are prebuilts that won't land updates until
several months in the future.
So add system properties so teamfooders can "force" apps to request
these permissions, making them work on Q builds. Only takes effect
when isolated feature is enabled, and guarded with STOPSHIP to ensure
we remove it.
Here's a typical set of commands to use with this CL:
adb shell setprop persist.fw.force_legacy 1
- or -
adb shell setprop persist.fw.force_audio com.google.android.music
adb shell setprop persist.fw.force_video com.google.android.apps.photos
adb shell setprop persist.fw.force_images com.google.android.apps.photos,com.google.android.apps.messaging
- then -
adb shell setprop persist.sys.isolated_storage 1
adb reboot

PropagateWorkSourceTransactListener intercepts outgoing calls and calls
Binde#setThreadWorkSource.
Also install the listener to system server to propagate the worksource
through binder calls.
Test: manual

There are multiple use cases for it:
1) Make it easy for another process to set the worksource. The
worksource can be propagated in a thread local - this is how gmscore and soon
system server works - the worksource can then be set for all binder
calls using
Object transactStarted() {
Binder.setWorkSource(ThreadLocalWorkSourceUid.get());
return null; // No token needed.
}
void transactEnded() {
Binder.setWorkSource(null);
}
This will be used by system process and gmscore.
2) SystemUI team was interested in detecting binder calls done from the
main thread in dogfood/tests. This listener will make it easy to figure
out which thread is used.
Performance impact of transact method:
- With current code: 45ns per call
- With this code: 57ns per call
This is not significant compared to the total binder call time which is
10-100s of microseconds.

As part of the storage changes in Q, we're removing the ability for
apps to directly access storage devices like /sdcard/. (Instead,
they'll need to go through ContentResolver.openFileDescriptor() to
gain access.) However, in several places we're returning raw
filesystem paths in the "_data" column. An initial attempt to simply
redact these with "/dev/null" shows that many popular apps are
depending on these paths, and become non-functional.
So we need to somehow return "_data" paths that apps can manually
open. We explored tricks like /proc/self/fd/ and FUSE, but neither
of those are feasible. Instead, we've created a cursor that returns
paths of this form:
/mnt/content/media/audio/12
And we then hook Libcore.os to intercept open() syscalls made by
Java code and redirect these to CR.openFileDescriptor() with Uris
like this:
content://media/audio/12
This appears to be enough to keep most popular apps working! Note
that it doesn't support apps that try opening the returned paths
from native code, which we'll hopefully be solving via direct
developer outreach.
Since this feature is a bit risky, it's guarded with a feature flag
that's disabled by default; a future CL will actually enable it,
offering a simple CL to revert in the case of trouble.

The original Process::readProcFile could only read files smaller than 256 bytes.
This change allows the function to read in larger files. For files smaller than
256 bytes, the added cost is only an extra read call, which returns zero.
Documentation has also been added to Process::readProcFile.

ContentProvider has a getCallingPackage() method, which verifies
the remote package name against the current Binder identity. When a
provider wants to clear that IPC identity, they need to clear both
the Binder state and the ContentProvider.getCallingPackage() state
together, so add methods to facilitate that.
Also fix subtle bug so we don't try translating relative paths.

In order to load a text file from an APK, it must be present
in the assets folder and be uncompressed. The AssetManager can
find assets from any application, so we point it at ANGLE. We
then pass the file descriptor, offset, and size, down to the loader
so it can parse json from the asset.

This commit adds the ability to enable debug layers for OpenGL ES.
Similar to Rootless Debug for Vulkan, layers can be loaded from the
APK or base directory of selected debuggable applications.
Layers will only be loaded when developers opt-in via settings for a
target application.
A separate application can now be specified as an additional location
for layer discovery.
Example usage:
adb shell settings put global enable_gpu_debug_layers 1
adb shell settings put global gpu_debug_app <target_app>
adb shell settings put global gpu_debug_layers layer1.so:layer2.so
adb shell settings put global gpu_debug_layer_app <layer_app>
