b1afd554fc Application Component Granularity MagiskHide
Before switching to the new MagiskHide implementation (APK inotify),
logcat parsing provides us lots of information to target a process.
We were targeting components so that apps with multi-processes
can still be hidden properly.

After switching to the new implementation, our granularity is limited
to the UID of the process. This is especially dangerous since Android
allow apps signed with the same signature to share UIDs, and many system
apps utilize this for elevated permissions for some services.

This commit introduces process name matching. We could not blanketly
target an UID, so the workaround is to verify its process name before
unmounting.

The tricky thing is that any app developer is allowed to name the
process of its component to whatever they want; there is no 'one
rule to catch them all' to target a specific package. As a result,
Magisk Manager is updated to scan through all components of all apps,
and show different processes of the same app, each as a separate
hide target in the list.

The hide target database also has to be updated accordingly.
Each hide target is now a <package name, process name> pair. The
magiskhide CLI and Magisk Manager is updated to support this new
target format.

99db0672b4 Minor MagiskHide adjustments
- 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

4eed6794c7 More MagiskHide optimizations
- Use a general procfs traversal function with callbacks
- Much better functions for killing 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.

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)
