692f893e1f Monitor /data/system/packages.xml 
Reinstalling system apps as data creates tons of issues.
Calling pm path <pkg> is extremely expensive and doesn't work in post-fs-data.
Parse through packages.xml to get APK path and UID at the same time.
As a bonus, we don't need to traverse /data/app for packages anymore.

f4f2274c60 Auto reinstall system apps on hide list 
Since we are parsing through /data/app/ to find target APKs for
monitoring, system apps will not be covered in this case.
Automatically reinstall system apps as if they received an update
and refresh the monitor target after it's done.

As a bonus, use RAII idioms for locking pthread_mutex_t.

c66cabd80f Several MagiskHide improvements 
- 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

24da3485bd Hardcode GMS unstable to MagiskHide 
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.

7384d2d330 Completely rework MagiskHide 
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.

1321f097b8 Remove usage of magisk.img 
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.

38fcc57bbf Use component name as targets 
Services can name their process name arbitrarily, for instance the service in
com.google.android.gms that is responsible for SafetyNet is named
com.google.android.gms.unstable. There are many apps out in the wild use
dedicated services with special names to detect root, and previously the user
is expected to add all of them to the hide list.

In this commit, we change from targeting process names to component names.
On Android, component names are composed of <pkg>/<cls>. When targeting
component names, we can always know what application spawned the new process.
This means that if the user adds a package name to the hidelist, MagiskHide can
now target ALL possible processes of that specific application.

To abide with this change, the default SafetyNet target is now changed from
com.google.android.gms.unstable (process name) to
com.google.android.gms/.droidguard.DroidGuardService (component name)
