It has been reported that CL "Make foreground and background I/O
priority different" causes Android devices equipped with eMMC storage
to reboot if there is sufficient I/O activity. Hence revert commit
7f3fe0aaf2.

In I3aad4b4b1d2f54db9e7ba86db8a655d8552bad0a we set MaxPerformance
for zygote64_32, and in I7fcceeb22b722c2164b9acf0b517a32ce34731fd
we synced up zygote64 to match this.
However, this change never made it into the zygote32 rc file,
which we fix here.

public.libraries.android.txt was not installable as it was used only
from microdroid. However, this module can also be used from system
image, as there is no difference from the content. This change marks the
module as no_full_install, so it can be installed in the system image
defined in Android.bp

Currently sanitizer.libraries.txt module is defined from Makefile, while
all logics to create the list of modules is implmented within the Soong.
This change moves sanitizer.libraries.txt module definition into Soong,
so it can be generated without sharing list of modules over Make
variable.

Previously llndk.libraries.txt definition was located in VNDK along with
other vndk related libraries.txt files. As of VNDK deprecation, all
other VNDK libraries.txt files are being removed, and there is no need
to keep llndk.libraries.txt whtin the VNDK project, as LLNDK is not
VNDK. This change moves definition of llndk.libraries.txt into system
core project, to keep with other files installed in /system/etc.

App metadata bundles, also known as Android Safety Labels (ASL),
contains information about the app's privacy and security practices.
This information is used to help users make more informed choices when,
for example, granting access to permissions.
ASL can currently only be preloaded on the system image or distributed
by the installer and written to a file in the app's codePath. To support
embedded ASL in APK we need to extract ASLs from APKs to a writeable
location. For non-preloaded apps we can write to the app's codePath like
the installer provided ASLs, however, we need to create a new writable
directory for preloaded apps located on read only partitions.

The default I/O priority is "best effort" so the combination of "none"
and "restrict-to-be" is not sufficient to make foreground and background
I/O priorities different. This CL makes sure that foreground and
background I/O priorities are different.
As one can see, this CL has the intended effect in Cuttlefish:
$ adb -s 0.0.0.0:6520 shell 'cd /dev/blkio && grep -aH . blkio.prio.class background/blkio.prio.class'
blkio.prio.class:promote-to-rt

Running snapshotctl involves talking to gsid, which requires the UID to

root user, this change adds system properties "sys.snapshotctl.map" and
"sys.snapshotctl.unmap" that proxy snapshotctl calls.

/metadta/aconfig/boot dirs
Create aconfig dirs on /metadata to store aconfig storage related files.
Under /metadata/aconfig we will store the following pb files:
1, aconfig_storage_location.pb, store the location of the storage files for
each container.
2, aconfig_flag_persistent_overrides.pb, store the local flag value overrides.
Under /metadata/aconfig/flags we will store flag value and info files
for each container, this include:
1, <container_name>.val flag value file
2, <container_name>.info flag info file
Under /metadata/aconfig/boot we will store read only flag value files
copied from /metadata/aconfig/flags at boot. These read only files are
used to serve flag read queries.

CL aosp/2929791 removed I/O priority support to prepare for a clean

v2 cgroup hierarchy. Since there was no other reason to revert the I/O
