Tuned rates that we collect PSS, to reduce how much we do
that heavy operation. Added a new way to determine
whether a process has changed to a state for the
"first" time -- now this is when it has gone to that
state for the first time since it was in a lower state.
This will reduce the amount of time we consider a
process to be first to only when it has previously
gone into a higher state than it had before.
Keep track of more fine-grained information about why we
collect a PSS sample (not just internal, but for a single
process, all processes because of a mem state change, all
processes because of a poll).
Started collecting RSS in various places, so we can start
looking at that w.r.t. PSS and see about transitioning to
it is a new primary metric.
Added logging for many of the places where the system
writes its configuration files, so we can more easily
see any bad behavior going on in those areas.
Added some currently disabled code to read smaps directly
instead of using fgets(). Probably won't help, but want
tot test.

During the proof-of-rotation additional attribute parsing, each
new certificate needs to be verified by the last. When doing this
verification, the ByteBuffer position is advanced to its limit, but
it needs to be read again to extract the certificate. Reset the
signedData ByteBuffer to its original position.

When ro.apk_verity.mode is on, full apk verification is only skipped if
the apk already has verity enabled in the file system, and if the apk
contains the Merkle tree root hash we need.
Since the configuration in the file system is duplicated from the apk
(including the offset and size of Signing Block and the Merkle tree),
in order to prevent offline attacker from changing it, we need to
measure the observed configuration and make sure it matches the kernel's
view.
Test: observed package manager's requeset to installd (only) for updated
priv apps.

Allows a uid that uploads a statsd config to additionally
register a BroadcastSubscriber with statsd. If statsd
detects an anomaly (according to the config's Alert),
statsd can inform a BroadcastSubscriber provided in the config.
The config uses a subscriberId (just an int) to identify the
BroadcastSubscriber. It then uses StatsManager.setBroadcastSubscriber
to associate that subscriberId with a given PendingIntent.
Then, when the anomaly is detected, statsd sends a broadcast
using that PendingIntent, alerting whoever was specified by
the config/setBroadcastSubscriber.

Since http://r.android.com/565744 , these classes do not appear
in the signature of any other Android API. There are no plans to
make them part of any future API signatures.
They do not provide useful abstractions because:
- They lack encapsulation and functionality (value is nonfinal;
lack of equals/hashCode and toString).
- It's trivial for apps to implement similar types for their
internal use.
Only three of these eight classes (Mutable{Int,Long,Boolean}) are
used internally in Android; most of these usages could be written
better with named, more specific classes.
Therefore these classes do not pull their own weight on the API
surface of android.util.
This CL deprecates all eight classes in preparation for removing
them from the Android API surface at some point in the future, and
to allow the unused classes to be removed entirely.

With the addition of APK Signature Scheme v3, the platform now can
support key rotation by using the proof-of-rotation provided by the
new scheme. Create a new API which allows checking of the entire
provided history of an APK's signing certificates, not just the
current signer. This should allow for changes of APK signing
certificates without fear of losing access to resources that would
have been provided under the old signing certificate.
Change getPackageInfo(GET_SIGNATURES) to return the oldest signing
certificate in the chain so that apps which do programmatic checks,
but are not updated to use the new API, still get the same information
they would have gotten had there been no rotation.

APK Signature Scheme v3 enables APK signing key rotation by allowing
an APK to embed a proof-of-rotation structure linking past signing
certificates to the current one. This information needs to be exposed
to the system before it can be used to make authorization decisions.

We changed the API to use long-based config keys instead of strings,
but we have some code that depends on the old API. Let's add them
back temporarily. The old API (that does nothing now) will be
deleted next month.
Test: N/A. Just to prevent build failures.
