Note:
This is for value metric. The default operations is sum the diffs.
The test uses kernel wake lock, which also needs dimension by kernel
wake lock name.
The test is a bit cumbersome as it needs StatsCompanionService to do
the alarm, which is not exact alarm.
The internal state of a slice of bucket would look something like this:
4:ipc0000005e_727_android.hardwar
0 0
4:SensorService_wakelock
40 64
4:ipc0000005c_727_android.hardwar
...

We can use the new mechanism to ask the calling shell to open
a file in order to implement the rest of these commands, allowing
you to give the path to an apk to install. That API is thus
extended to allow you to open readable files, not just opening
file for writing.
Doing this however means we no longer can pass a file path to
AssetManager for the apk to parse, we only have an already open
fd for that. Extending AssetManager to allow adding apks from
fds is not that hard, however, since the underlying zip library
already supports this.
This main thing this changes is in AssetManager.cpp where we
retrieve the open zip file for a particular apk that has been
added. This used to look up the zip file by path every time
it was needed, but that won't work anymore now that we can have
things added by fd. Instead, we keep track of each opened zip
in the AssetManager, so we can just directly retrieve it from
the asset_path representing the item that was added. As a
side-effect, this means for normal paths we no longer need to
look up by name, but just have the opened zip file directly
accessible. (This is probably good, but it does mean that we
no longer run the logic of seeing if the zip file's timestamp
has changed and re-opening it if it has. We probably shouldn't
be relying on that for an active AssetManager anyway, and maybe
it is even good that we don't allow the zip file to change
under it?)
A follow-up change will finally remove the Pm.java implementation
and turn the pm "command" into a simple shell script that runs
cmd package.

The only thing printed besides the stack elements is the classname `LogStackTrace`.
This is useless.
We can improve performance by only parceling around the StackTraceElement[] instead of serializing the whole Throwable.

Fixes several issues with the way PendingIntents are being whitelisted
from background check with Notifications. Most visibly, this causes the
whitelisting not to work on Notifications that use the DecoratedContentViewStyle,
but there are some conditions where the whitelisting breaks for regular
notifications too.
- After a Notification is rebuilt with Notification.Builder, the set
of PendingIntents in the notification was not rebuilt.
This broke the whitelisting whenever a PendingIntent is added after
the Notification was already sent once. Workaround for broken platform
releases: always use a fresh Notification object, or clone before
sending.
- Fixes PendingIntent.writePendingIntentOrNullToParcel to invoke the
OnMarshalListener.
This broke whitelisting for any PendingIntents attached to custom
RemoteViews. Workaround for broken platform releases: Also attach
the PendingIntent to the Notification's extras.
- Changes RemoteViews to keep the parcel cookies that were present
during unparceling, such that they can be reapplied when it gets
cloned.
This broke whitelisting for any PendingIntents attached to a
DecoratedContentViewStyle *even if added to extras*. Workaround
for broken platform releases: none.
- Fixes Notification.whitelistToken mistakenly being static.
There's an unlikely race condition where the field could be
overriden with null by an incoming notification right as another
notification is sent out. Workaround for broken platform releases:
none.

This removes all GlobalRef allocation as part of building BinderProxys.
Previously these were used to map IBinders to the corresponding
Java object, so the Java objects could be reused. We now keep
that mapping at the Java level.
This means we often need to call into Java to look up or allocate
a BinderProxy. But this replaces a prior call to Java to dereference
a WeakReference. The Java custom Java map-to-WeakReference data
structure is probably not terribly efficient, but the original
attachement mechanism did not seem to be either. And this
avoids potentially even more catastrophic issues when the number
of GlobalRefs approaches its limit.
We decrease GC triggering frequency from 200 to 1000 allocated
references. This now only applies to other kinds of JNI References
allocated by Binder.
I saw a maximum bucket size of 16 for the ProxyMap data structure
while briefly exercising a freshly booted device. That occurred
in system_server.

Change the Java BinderProxy to only contain a single native pointer,
so that we can get by with a single NativeAllocationRegistry
registration. This adds some indirections and a new allocation. But it
marginally reduces the number of (expensive) JNI field lookups from
native code, and the extra allocation involves significantly less
overhead than registering each object twice. This also cleans up the
code a little by avoiding some explicit reference count adjustments.
Change BinderProxy Binder to use NativeAllocationRegistry instead of
finalize().
Change the mObject field in Binder to hold a non-reference-counted
but owning pointer to JavaBBinderHolder. Have JavaBBinderHolder no
longer inherit from RefBase.
Make it clear that neither Binder.mObject, not BinderProxy.mNativeData
can be null. Remove null checks.
Avoid checking for null returns from C++ new. It would throw
anyway, which would cause the process to abort.
Test: Booted master.

(cherry picked from commit 4cd650c008)
Everything is now moved out of the pm command except for
the various install commands. I am going to hold of on
those since they require doing some resolution with the
current implementations in the package manager to make
sure they match and behave identically to the implementations
currently in the pm command. But other than that, everything
in pm is now just redirecting over to "cmd package".
Also fix up some of the dumpsys output of a few other sevices
when asking to print the data for a particular package, so
the "pm dump" command gives a little more sane result.

Previously, pulled data was returned as a string. We instead
return the data as an array of StatsLogEventWrapper, which encodes
using the binary-encoded format liblog uses. StatsD uses the same
parsing as for pushed events to convert these. This CL also fixes
the parsing of log_msg since the strings were previously emptied
before we had a chance to read the values.
Note that the cpp-aidl can't support List of Parcelable, so we
have to return the results as an array.
Test: Manual using the new command in StatsService to print results.
Also created a new unit-test by creating a dummy pull code of -1,
but this test is deleted since it required creating a fake output in
StatsCompanionService.
