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.
Samsung does not like running cmd before system services are started.
Instead of failing, it will enter an infinite wait on binder.
Move APK installation to boot complete to make sure pm can be run
without blocking process.
Forseeing the future that more and more A only system-as-root devices
would have similar bootloader behavior as the latest Samsung devices
(that is, no ramdisk will be loaded into memory when booting from
the boot partition), a solution/workaround has to be made when Magisk
is installed to the recovery partition, making custom recoveries
unable to co-exist with Magisk.
This commit allows magiskinit to read input device events from the
kernel to detect when a user holds volume key up to toggle whether
system-as-root mode is enabled. When system-as-root mode is disabled,
magiskinit will boot with ramdisk instead of cloning rootfs from system,
which in this case will boot to the recovery.
