This patch removes several debugging log messages. These messages were
useful when the `FDs to ignore` list was usually empty, but with the
addition of USAPs this has become spammy.

This patch adds native support for spawning and managing blastula pools,
as well as several code cleanups and modernizations.
Changes includes:
* A function to fork blastulas
* A table for managing blastula-related data
* Functions for adding and removing blastula data from the
aforementioned table
* Switching from NULL to nullptr
* Replacing string-passing error handling with a curried failure
function
* Utility functions for handling managed objects
* JNI functions for blastula pool management

Due to b/30963384, every time zygote creates a new child, zygote reopens
all existing file descriptors, taking careful measures to preserve the
file status flags, file descriptor flags, and seek offset. However, dup2
resets the sole file descriptor flag (FD_CLOEXEC) on duplication,
defeating the hard work done to preserve the flag.
From "man dup"
NAME
dup, dup2, dup3 - duplicate a file descriptor
DESCRIPTION
The dup() system call creates a copy ...
...
The two file descriptors do not share file descriptor flags
(the close-on-exec flag). The close-on-exec flag
(FD_CLOEXEC; see fcntl(2)) for the duplicate descriptor is off.
...
The dup2() system call performs the same task as dup() ...
Use dup3 instead to allow us to preserve the FD_CLOEXEC status.

Prepare the idmap and asset managers for interfacing with idmap2 instead
of today's installd + idmap pipeline, but don't make the switch just
yet.
Instead, idmap2 runs as its own native daemon with an AIDL interface.
This removes the need for installd to fork and exec on each idmap call,
saving about 50 ms per call.

This allows users to target zygote for heap profiling without
causing it to crash on ForkCommon.
This also allows us to profile zygote in benchmark runs where we want to
profile as many processes as possible.

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]

Test: `mm` under frameworks/base/tests/[libs|privapp]-permissions
adb sync && adb reboot
adb shell cmd package list libraries

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.
