This creates a new vzwomatrigger_app domain. The domain is
currently in permissive mode (for userdebug and eng builds), while we
observe the SELinux denials generated and update permissions.

Test: Build, flash, boot successfully

The property is set to inform kernel to do a warm_reset on the next
reboot. This is useful to persist the logs to debug device boot
failures. More details in http://go/rvc-ota-persist-logs.
The property is set to 1 by update_engine after an OTA. And it's set to
0 by update_verifier or vold after we mark the current slot boot
successful.
The property is read by vendor_init. And according to its value,
vendor_init writes a particular sysfs file to schedule a warm reset
on the following reboot.
Without the new context, the denial message says:

In normal Android, libsnapshot interacts with libfiemap over binder (via
IGsid). There is no binder in recovery, so instead, we directly link to
the library and therefore need appropriate sepolicy changes.
Bug: 139154945
Test: no denials in recovery or fastbootd

Looking at go/sedenials, we're fairly confident that this domain has all
the necessary permissions. This change enforces all the defined rules
for the permissioncontroller_app domain and unsets the permissive mode.
Bug: 142672293
Test: Build successfully, flashed a phone and basic usage of Permission Manager seemed to work well.

Android is moving away from debugfs. Information from /d/wakeup_sources
and /d/suspend_stats is now also exposed in sysfs under
/sys/class/wakeup/* and /sys/power/suspend_stats/* respectively:
https://lkml.org/lkml/2019/7/31/1349https://lkml.org/lkml/2019/8/6/1275
Allow SystemSuspend to read those sysfs nodes.
One caveat is that /sys/class/wakeup/wakeupN can be a symlink to a
device-specific location. In this case, device sepolicy should label
that the files appropriately. This is similar to how device policy
applies "sysfs_net" and "sysfs_batteryinfo" labels.
Bug: 144095608
Bug: 129087298
Test: boot cuttlefish; system_suspend is able to read
/sys/power/suspend_stats/* and /sys/class/wakeup/*

init should register native services with lmkd so that they can be killed
when necessary. Allow init to communicate with lmkd over dedicated socket
the same way AMS does. Allow lmkd to kill and manipulate native processes
that were registered with lmkd.
Bug: 129011369
Test: boot and verify native service registration
Test: verify lmkd can kill registered native processes using lmkd_unit_test

Relax the requirement to have both seinfo and name specified for
privapps. The original reason for requiring both was because, normally,
a package can only be uniquely specified by both name and signature,
otherwise package squatting could occur. However, privapps are
pre-installed, so the concerns about the potential for package squatting
are eliminated. This change will drastically simplify sepolicy
configuration for priv-apps.
Bug: 142672293
Test: Flashed a device with this build and verified
com.google.android.permissioncontroller still runs in the
permissioncontroller_app domain.

System_server will read this property to determine if it should
expect the lmkd sends notification to it on low memory kills.

In emulator builds without OpenGL passthrough, we use software rendering
via SwiftShader, which requires JIT support. Therefore, we need to allow
system_server to use execmem so that it can run JITed code. These builds
are never shipped to users.
