With the new xt_bpf support for iface stats. We no longer need to parse
the per interface stats from /proc/net/dev. And since the old xt_qtaguid

This CL adds the basics to set black, dark gray or light gray list
enforcement, rather than just black as before. It's not possible to
actually set the policy per-package yet.
PackageDexOptimizer still uses a single bit, for API checks on/off, rather
than the new enum. It assumes blacklist enforcement internally. This can
be improved in a follow up CL.

This uses the new ZygoteProcess.startChildZygote() method to launch the

This adds a new --start-child-zygote argument that instructs the main
zygote to create a new child process that will also be a zygote. The
system_server generates a random name in the abstract socket namespace
for it and the child-zygote to communicate over, and that is passed as
an argument to the new process.
A child-zygote bypasses the normal post-fork-child of the zygote process
in order to preserve itself as a zygote. This means not starting the
Binder threadpool nor launching into ActivityThread. Instead, a
child-zygote calls into its own main function. The main function runs a
ZygoteServer select loop, listening on the socket name specified by the
system_server when it was forked.
Unlike the system zygotes, a child-zygote can be killed without bringing
down the system. Killing a child-zygote will not terminate its child
processes, which will be reparented to init for reaping when they
eventually exit.

Extend the installd profile interface to take the profile name as
argument. This shifts the responsibility for choosing the names of
profiles for primary apks completely to PackageManager. Each of the
application code paths will get an unique profile name based on their
split name.
All the profile operations will now work on a specific profile name rather
than assuming a default global name.
Also, move dumpProfiles and clearProfiles functionality to the
ArtManagerService so that we can re-use profileName computations easier.

Add support in the package installer to install dex metadata files
alongside the application apks (base or splits).
During installation or update the dex metadata files will need to have a
matching apk file. The matching is done by checking the file extension
(e.g. base.apk -> base.dm, split_a.apk -> split.dm).
On disk, the metadata files are placed next to the apks.
The .dm files will be used during install-time optimizations and passed
verbatim to dex2oat.

There will be the following situations about mApplicationObject：

then set mApplicationObject.
2) fork system_server， don't set mApplicationObject value.
3) using app_process fork process except zygote, will inovke RuntimeInit,
don't set mApplicationObject value。
For example using command as below:
app_process /system/bin com.android.commands.am.Am "$@",
if this process throw uncaught exception，will output FATAL EXCEPTION IN SYSTEM PROCESS log，
it's not in system process but in normal process。
so should add condition： Process.SYSTEM_UID == Process.myUid()

This allows us to maintain NetworkStats entries that track
whether the traffic was on the default network.
At the moment, the stats collection code always passes in
DEFAULT_NETWORK_NO. However, this value is a no-op, since it is
not persisted to disk. Only the ident, the uid/set/tag, and the
packet/byte/operation counters are persisted.
A future change will add defaultNetwork to the ident and start
persisting it.

Before this change, seccomp filter setup is as early as in zygote's main
function. To make it possible to split app and system server's filter,
this postpone the setup to after fork. It also starts to call app
specific and system server specific setup function.
The filter setup is done in Zygote's ForkAndSpecializeCommon. This is
because adding a seccomp filter must be done when either the caller has
CAP_SYS_ADMIN or after the PR_SET_NO_NEW_PRIVS bit is set. Given that
setting PR_SET_NO_NEW_PRIVS breaks SELinux domain transition
(b/71859146), this must be done after Zygote forks but before
CAP_SYS_ADMIN is droppped.

In terms of performance since this happens at fork, the measure shows
the overhead is negligible. Assuming 130 instruction in the BPF, on
walleye, even when running on little core with fixed low frequency, each
setup took about 60.9us on average. When it runs on big core with
higher frequency, it took about 39.3us.
