- Fail fast on unsupported systems
- Show proper fail message on unsupported systems
- inotify_fd shall be swapped out before closing to prevent
the proc_monitor thread to read from incomplete inotify fd
- Directly get UID instead of traversing /data/data everytime
- Use /data/user_de/0 instead of /data/data on Android 7.0+
- Update hide_uid set incrementally when adding/initializing targets
- Guard hide_uid set with the same lock as hide_list vector
- Do not add GMS package into database; only add to in-memory list
With the new detection method, it is impossible to check for components.
Remove additional checks for components and simply hardcode string to
proc_monitor.cpp and query cmdline to see if it's GMS unstable.
This addresses wasted resources on applying custom namespace
on all GMS processes.

Previous MagiskHide detects new app launches via listening through logcat
and filtering launch info messages.
This is extremely inefficient and prone to cause multiple issues both
theoratically and practically.
Rework this by using inotify to detect open() syscalls to target APKs.
This also solves issues related to Zygote-forked caching mechanisms such as
OnePlus OxygenOS' embryo.

Mounting ext4 images causes tons of issues, such as unmountable with broken F2FS drivers.
Resizing is also very complicated and does not work properly on all devices.
Each step in either measuring free space, resizing, and shrinking the image is a
point of failure, and either step's failure could cause the module system completely broken.
The new method is to directly store modules into /data/adb/modules, and for module installation
on boot /data/adb/modules_update. Several compatibility layers has been done: the new path is
bind mounted to the old path (/sbin/.magisk/img), and the helper functions in util_functions.sh
will now transparently make existing modules install to the new location without any changes.
MagiskHide is also updated to unmount module files stored in this new location.
