- this would likely occur on an FDE device with block map OTAs (a la LineageOS) since they do not require/request decrypt
- for reference all other addon.d "v1" cases should work fine:
1) FDE with openrecovery script works fine since it requests decrypt
2) FBE with openrecovery script OR block map work fine since /data/adb remains accessible
We used to construct /sbin tmpfs overlay in early-init stage after
SELinux is properly initialized. However the way it is implemented
(forking daemon from magiskinit with complicated file waiting triggers)
is extremely complicated and error prone.
This commit moves the construction of the sbin overlay to pre-init
stage. The catch is that since SELinux is not present at that point,
proper selabel has to be reconstructed afterwards. Some additional
SEPolicy rules are added to make sure init can access magisk binaries,
and the secontext relabeling task is assigned to the main Magisk daemon.
Some stupid Samsung ROMs will spawn multiple zygote daemons. Since we
switched to ptrace based process monitoring, we have to know all zygote
processes to trace. This is an attempt to fix this issue.

Since Android Q does not allow launching activities from the background
(Services/BroadcastReceivers) and our native process is root, directly
launch activities and use it for communication between native and app.
The target activity is not exported, so non-root apps cannot send an
intent to fool Magisk Manager. This is as safe as the previous
implementation, which uses protected system broadcasts.
This also workaround broadcast limitations in many ROMs (especially
in Chinese ROMs) which blocks the su request dialog if the app is
frozen/force stopped by the system.
Close#1326
We upgrade compileSdkVersion to Q, but keep targetSdkVersion as 28.
The reason is because targeting Q will no longer allow us to execute
native binaries in an app's private data, which Magisk Manager relies
a lot for performing stock boot image patches in non rooted environment.

Some workarounds has been discovered (https://github.com/termux/proot),
however for the time being there is no point to introduce these huge
hacks just for targeting Q, which we don't benefit anything.
The root nodes are /system and /vendor. Adding new files into these
directories, although works on some devices, mostly bootloops on many
devices out there. So don't allow it, which also makes the whole magic
mounting logic much easier and extensible.
