Run throne_tracker() in kthread instead of blocking the caller.
Prevents full lockup during installation and removing the manager.
By default, first run remains synchronous for compatibility purposes
(FDE, FBEv1, FBEv2)
Features:
- looks and waits for manager UID in /data/system/packages.list
- run track_throne() in a kthread after the first synchronous run
- prevent duplicate thread creation with a single-instance check
- spinlock-on-d_lock based polling adressing possible race conditions.
Race conditions adressed
- single instance kthread lock, smp_mb()
- track_throne_function, packages.list, spinlock-on-d_lock based polling
- is_manager_apk, apk, spinlock-on-d_lock based polling
This is a squash of:
https://github.com/tiann/KernelSU/pull/2632
Original skeleton based on:
`kernelsu: move throne_tracker() to kthread`
`kernelsu: check locking before accessing files and dirs during searching manager`
`kernelsu: look for manager UID in /data/system/packages.list, not /data/system/packages.list.tmp`
