SocketUtils contains system APIs for modules to interact for sockets,
wrapping internal APIs. It should be part of the platform to keep access
to the internal APIs.
This involves splitting NetworkUtils.protectVpn to NetworkUtilsInternal,
since SocketUtils and VpnService are the only users of that method.
The @UnsupportedAppUsage NetworkUtils.protectVpn has low usage
count, and is already available through VpnService.protect.

memtagMode allows an app to opt in to MTE in either sync or async mode.
nativeHeapZeroInit enables automatic initialization of heap memory.
Both attributes default to off and can be specified at either
application or process level.

Do not return to Java mode between consecutive fork operations.
This greatly reduces the Zygote overhead, since we no longer need to
stop and restart Java daemons.
By not switching back to Java mode, and being careful about what memory
we touch between forks, we also keep the Zygote heaps much more stable,
facilitating page sharing between the zygote and all its children.
Under normal operation we should no longer allocate any memory in the
zygote between forks. That applies to both the Java and C++ heap.
This makes the zygote behave much more like the mental model many
of us had assumed: It has nearly constant memory contents, which are
copy-on-right cloned at each fork. This does not apply to the initial
system server and webzygote forks, that are currently still handled
differently.
This includes
1. Add ZygoteCommandBuffer, and switch the argument parsing code to use it.
This slightly reduces allocation and enables (3).
2. Support process specialization in the child, even when the arguments
are already know, Leverages existing Usap code.
3. Add support for forking multiple child processes directly to the
ZygoteCommandBuffer data structure. This directly uses the buffer
internals, and avoids returning to Java so long as it can handle the
zygote commands it sees.
FUNCTIONALITY CHANGE:
We now limit the total size of the zygote command, rather than the
number of arguments.
Initial performance observations:
[ These are not perfect, since I'm comparing to numbers before I
started. There may have been other moving parts, but they should be
minor. ]
System-server-observed launch latency:
[Not the best metric, but easy to measure. In particular, this
does not represent a significant reduction in application launch
time.]
Based on measuring the last 10 launches in a lightly used cf AOSP
instance, the system server latency from requesting an app launch to
response with the pid (which does not require the child to execute
anything) went from an average of about 10.7(25) msecs to 6.8(9) and
7.9(16) in two tries with the CL. (The parenthetical numbers are
maxima from among the 10; the variance appears to have decreased
appreciably.)
Dirty pages:
The number of private dirty pages in the zygote itself appears to have
decreased from about 4000 to about 2200. The number of dalvik-main
private dirty pages went from about 1500 to nearly zero.
Initially ART benchmarking service claim -1.88% in PSS. But this is not
consistently repeatable.
Drive-by fix:
Call setAllowNetworkingForProcess on usap / native loop path.

This CL cleans up some warnings in the ZygoteInit.java and

to code in Zygote.java and ZygoteConnection.java were needed due to
function signature changes.

Instead of classifying interfaces by network type in BatteryStats,
classify them based on the transports array provided by the
NetworkAgent.
Network types are deprecated and transports should be used instead. This
change allows BatteryStats to stop depending on unstable APIs such as
isNetworkTypeMobile.
This change also updates nullability annotations in ConnectivityService
and NetworkAgentInfo to show that the NetworkCapabilities are non-null
(as provided by the network agent) when calling
noteNetworkInterfaceTransports.
