BitUtils is a fairly generic place where all framework engineers should
be able to contribute reusable code.

When native layer reports onDnsEvent, netId, eventType and
returnCode are available only in NetdEventListenerService, but
not for the clients who register event on it.
Thus, extend the callback to give clients more detail on the
network the look up was performed on and the result of the
lookup.

When using xt_qtaguid to count per uid stats,
NetworkStatsService needs to adjust the 464xlat traffic since
iptables module would double count for ipv4 and ipv6 packet.
But for eBPF, the per uid stats is collected in a different
hook, so the adjustment on root uid would only be needed in tx
direction.

usage.

Shadow call stack (SCS) is a security mitigation that uses a separate
stack (the SCS) for return addresses. In versions of Android newer
than P, the compiler cooperates with the system to ensure that the
SCS address is always stored in register x18, as long as the app was
compiled with a new enough compiler and does not use features that
rely on SP-HALs (this restriction is because the SP-HALs might not
preserve x18 due to potentially having been compiled with an old
compiler as a consequence of Treble; it generally means that the
app must be a system app without a UI). This change makes it so that
we temporarily store the address on the stack while preloading the
SP-HALs, so that such apps can use the same zygote as everything else.

Based on some analysis, these fields/methods are likely false positives.
Set maxTargetSdk=P so that any apps using them are required to migrate off
them in future. See the bug for more details.

(cherry picked from commit 8c854f86a4)
Based on recent measurements, storage pools of small objects are
generally not useful.
We ran into this because growing ArrayDeques are potentially very
unfriendly towards a generational GC, and racing recycle calls
can cause it it grow beyond MAX_POOL_SIZE. This isn't a big deal,
but there's no reason we should even be thinking about it.

The extractNativeLibs property was ignored by the package installer
for environments with native bridge. This is not neccessary since
native bridge implementations are required to support
open-directly-from-apk feature and in this respect are not different
from environments without native bridge.

ExternalStorageProvider always throw exception when renameDocument

beforeVisibleFile is not exist after rename, it will throw

KernelCpuProcReader used FileChannel to dump bytes into a large enough
ByteBuffer. However, FileChannel#read stops as soon as there is nothing
left to read. Since the kernel may not deliver all parts of a proc file
simultaneously, previous read mechanism would possibly read only a
portion of the proc file. The impact is that KernelUidCpuFreqTimeReader
gets an incomplete UID list.
New mechanism uses a loop to turn non-blocking FileChannel#read into a
blocking operation. It does not return until hitting EOF. The reason
not to use Files#readAllBytes is that we want to reuse the byte[].
