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.

This CL will support the followings.
- installing a RRO package for framework from /product/overlay
- installing apps from /product/app
- installing priv-apps from /product/priv-app
- installing permissions from
/product/etc/[default-permissions|permissions|sysconfig]
Bug: 64195575
Test: `mm` under frameworks/base/tests/[libs|privapp]-permissions
adb sync && adb reboot
adb shell cmd package list libraries
=> confirmed com.android.test.libs.product library
adb shell cmd package dump \
com.android.framework.permission.privapp.tests.product
=> confirmed that the package is a priv-app
And I moved vendor/overlay/framework-res__auto_generated_rro.apk into
system/product/overlay/ on sailfish, and I confirmed that the RRO was
installed properly.

Add file descriptors that should be ignored in the file descriptor
table check.
Use this to ignore the pipe file descriptors when starting an app
with invoke-with (wrapper).

This refactors the whitelist to be a class, rather than just a static C array.
The whitelist can then be augmented dynamically when the package path is known
in the webview_zygote.
