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.

Currently ZygoteProcess only uses String names in the RESERVED socket
namespace. This CL reworks the class to use LocalSocketAddress, so that
other socket namespaces can be used to communicate with zygotes.

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.

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.
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.

Add a method to compute the size of a ProxyMap without cleared
references. Use it in the crash decision. Report both counts, as
well as the count after a forced GC before actually crashing.
Rename the histogram generating function after a small refactoring
to make that easier.
When we crash, we now generate a message like the following
(generated here with reduced thresholds):
01-03 01:40:52.273 4793 4947 E JavaBinder: java.lang.AssertionError:
Binder ProxyMap has too many entries: 277 (total), 275 (uncleared),
257 (after GC). BinderProxy leak?
after the histogram. Unfortunately, the intervening GC may take some
time, and other intervening messages may sneak into the log between
them.
Experiments so far suggest that none of this greatly affects the
decision when to die. But this eliminates uncertainty as to whether
there was really a problem.

In general, using Mutable inside of structures
or as API arguments is a code smell. However, it
is the most syntactically clean way of fetching
something out of a lambda or inner class.
Using this, one can do:
Mutable<Result> res = new Mutable<>();
hidlObject.foo((...) -> {
res.value = ...;
});
There is an alternative:
Result a[] = new Result[1];
hidlObject.foo((...) -> {
a[0] = ...;
});
However, this alternative syntax is relatively messy.

Settings application shows internal storage size using API getTotalBytes in StorageStatsManager.
This API calls getPrimaryStorageSize() in StorageManager.
getPrimaryStorageSize() returns /data parition size calculated API roundStorageSize() in FileUtils.
Using this API, total primary storage size returns 8GB if 16GB emmc size device has /data partition size below 8GB.
So we should modify getting of primary storage size close to real emmc size.
getPrimaryStorageSize() will be calculated sum of /data and /system partition size.
Test: Check primary storage size in Settings application

GSI disables AVB by overriding vbmeta partition.
When a device can run runtime vintf checking, it should already
pass AVB, so we don't need to check AVB in runtime vintf.
We cannot change the original VintfObject.verify() because AVB check is
still needed for android.os.RecoverySystem to verify a newly downloaded
OTA package.

This fails when trying to run the AOSP mailer with CRASH_AT_SIZE = 500,
when the check interval is reduced sufficiently so that the test is
actually executed. System server has been observed to use more than
1000 BinderProxies. Thus 5000 seems like roughly the lowest safe limit.
Note that the test is executed somewhat rarely, so we may exceed
this number by quite a few before we actually crash.
