The first-stage init has been built in Make due to some requirements
(like placing it directly under the root directory rather than bin/, and
creating mountpoints like /proc, etc.) that are not supported in Soong.
However, Ie06dc5a93635ea8b1e18be517ed8615b6c82fee6 will make it possible
to satisfy the requirements in Soong. The build of the boot image is
done in Soong and we can create mount points using the `dirs` property
and create a symlink /init that points to /bin/init_vendor using the
`symlinks` property.
To complete the picture of build everying in Soong, this change adds a
Soong-version of the first-stage init.
Note that the Soong-based boot image creation is currently only for the
microdroid usecase. Therefore, the Android.mk-based first-stage init
still remains and will be removed later.

we don't do the transition and allow the daemon to continue which

ueventd.rc scripts belong in the /etc/ directory of their given
partition, not the root of the partition. This can cause problems,
especially since Android.bp cannot write to the root directly, forcing
vendors to use Android.mk for these files. Note that
/system/etc/ueventd.rc moved long ago.

During device bringup, dynamic partitions may not be properly
configured by some sort of build or load misconfiguration. Diagnosing
such issues can be difficult without being able to see which partitions
are available and what they contain.
Aditionally, making logical partitions available to first stage console
permits early mounting of vendor partition and allows primitive
validation of vendor scripts without requiring full Android
environment. For instance, vendor_dlkm partition and modules can be
probed needing to have a full Android bootup.
Creation of logical partitions is done only when first_stage_console is
requested in order to have minimal impact on normal boot. Thus, only a
small refactor is required to split CreateLogicalPartitions out of
MountPartitions.

This change will help non-user builds with keeping debugfs
disabled during run time. Instead, debugfs will be mounted by init
to enable boot time initializations to set up vendor debug data
collection and unmounted after boot. It will be also be mounted by
dumpstate for bug report generation and unmounted after.
This change is only intended to help vendors (who depend on debugfs to
collect debug information from userdebug/eng builds) keep debugfs
disabled during runtime. Platform code must not depend on debugfs at all.

With compressed VAB updates, it is not possible to mount /system without
first running snapuserd, which is the userspace component to the dm-user
kernel module. This poses a problem because as soon as selinux
enforcement is enabled, snapuserd (running in a kernel context) does not
have access to read and decompress the underlying system partition.
To account for this, we split SelinuxInitialize into multiple steps:
First, sepolicy is read into an in-memory string.
Second, the device-mapper tables for all snapshots are rebuilt. This
flushes any pending reads and creates new dm-user devices. The original
kernel-privileged snapuserd is then killed.
Third, sepolicy is loaded from the in-memory string.
Fourth, we re-launch snapuserd and connect it to the newly created
dm-user devices. As part of this step we restorecon device-mapper
devices and /dev/block/by-name/super, since the new snapuserd is in a
limited context.
Finally, we set enforcing mode.
This sequence ensures that snapuserd has appropriate privileges with a
minimal number of permissive audits.

* In 'ActivateFlattenedApexesFrom', the 'readdir' detects
the APEX folders in a random way that depends on filesystems,
built packages and order of the build chain
* In normal cases, this is not an issue, however when building
with Go configurations, we have a case where the package
'com.android.tethering.inprocess' is built along the
'com.android.tethering' overriden binary, and depending on
the 'readdir' output, the mounts break the Tethering service

The firmware_handler.HandleAbort and subcontext.RecoverAfterAbort
tests intentionally abort in the child process to ensure that
ueventd/init can recover if their child processes die. This generates
a tombstone which causes confusion. This change resets SIGABRT to
SIG_DFL right before the abort(), so that the child processes will
exit normally without generating a tombstone or writing a crash to
logcat.

If a `*` appears within (but not at the end) of a /dev or /sys path in
a ueventd.rc file, then that path is matched with fnmatch() using the
FNM_PATHNAME, which means `*` will not match `/`. That is not always
the intended behavior and this change creates the no_fnm_pathname
option, which will not use the FNM_PATHNAME flag and will have `*`
match `/`.

Current implementation updates the permissions of sysfs
nodes of a device upon the following actions: "add",
"change" and "online".
But certain sysfs nodes (ex: wakeup capabilities under
power management) of devices are not present when the
device is added, but these are generally dependent on
the device driver and are added once the driver is bound.
This is particularly common in USB host stack.
If the bind action events are not parsed the ueventd
will not update the permissions of these nodes.
Hence, add the support for updating permissions on
bind action as well.
