98813c24fb Drop trailing garbage of gzip decompress 
I previously refered to minigzip from libz which copies all trailing

hand, drop trailing garbage by default. Consider ZIMAGE append
the kernel size with zero padding, we should drop trailing garbage
as well.

a1ce6f5f12 Fix race condition when switching root manager 
Before this change, the root manager package name is only written into
the database after the repackaged APK is installed. In the time between
the repackaged APK being installed and the package name being written
into the database, if some operation calls `get_manager`, the Magisk
daemon will cache this result and ignore the repackaged APK, even if
the package name is set afterwards, because the cache won't be
invalidated. The result is that the repackaged manager APK will not be
recognized as the root manager, breaking the hide manager feature.

This race condition is more likely to happen when Zygisk is enabled,
because `get_manager` is called with a very high frequency in that case.

To fix the issue, we have to set the new package name into the database
BEFORE installing the repackaged APK. We also stop pruning the
database if the repackaged manager is not found, moving this logic into
the Magisk app. By doing so, we can guarantee that the instant after
the repackaged manager APK is installed, the Magisk daemon will
immediately pick it up and treat it as the root manager.

Another small optimization: when the requester is root, simply bypass
the whole database + manager package check. Since the Magisk app hiding
APK installation proces will call `su` several times to run `pm` under
different UIDs, doing this opimization will reduce the amount of
unnecessary database query + filesystem traversals.

af01a36296 Refactor magic mount to support overlayfs 
Previously, magic mount creates its own mirror devices and mount
mirror mount points. With these mirror mount points, magic mount
can get the original files and directory trees. However, some
devices use overlayfs to modify some mount points, and thus after
magic mount, the overlayed files are missing because the mirror
mount points do not contain the overlayed files. To address this
issue and make magic mount more compatible, this patch refactors
how magic mount works.

The new workflows are as follows:
1. make MAGISKTMP a private mount point so that we can create the
   private mount points there
2. for mirror mount points, we instead of creating our own mirror
   devices and mount the mirror mount points, we "copy" the
   original mount points by recursively mounting /
3. to prevent magic mount affecting the mirror mount points, we
   recursively set the mirror mount points private
4. to trace the mount points we created for reverting mounts, we
   again make the mirror mount points shared, and by this way we
   create a new peer group for each mirror mount points
5. as for tracing the newly created tmpfs mount point by magic
   mount, we create a dedicated tmpfs mount point for them, namely
   worker mount point, and obviously, it is shared as in a newly
   created peer group for tracing
6. when reverting mount points by magic mount, we can then trace
   the peer group id and unmount the mount points whose peer group
   ids are created by us

The advantages are as follows:
1. it is more compatible, (e.g., with overlayfs, fix #2359)
2. it can mount more partitions for which previous implementation
   cannot create mirror mount points (fix #3338)

No kernel repack if it isn't patched at all 
It turns out that decompressing and recompressing the kernel is enough to break booting on many devices that use MT6763.

Refactor sepolicy.rules resolve 
We resolve available partitions for sepolicy.rules when patching
boot and bind mount the partition by magiskinit.

For older devices, the previous logic won't work because the part name
is never readable.

8423dc8d63 Later check persistent_properties 
`daemon_entry` calls `getprop` which initializes sysprop impl and checks whether we need to load persistent property file. On FDE devices, magiskd starts before /data is actually decrypted, and the check always fails. Thus `persist_getprop("persist.sys.safemode")` will always fail.

1f8c063dc6 Fix booting into recovery with Android 13 GKI kernels 
With Android 13 GKI kernels, the boot partition has no ramdisk, so
Magisk constructs one from scratch. In this scenario, there's no backup
init binary at /.backup/init. For normal boot, magiskinit will symlink
/init -> /system/bin/init if needed. This commit implements the same
for booting into recovery. Before, magiskinit would just exec itself
over and over again because it couldn't restore the backup init.

7505599ea0 Skip invalid slot_suffix argument 
Many Amlogic devices (e.g. FireTV 2nd gen Cube, Vero 4k+, MI Smart Speaker, etc.) are A-only with androidboot.slot_suffix=normal argument. I think "normal" actually means A-only in this case so just ignore it.

448384af06 Guard su request IPC 
Previously `read_string()` calls `std::string.resize()` with a int read from remote process. When I/O error occurs, -1 will be used for resizing the string, `std::bad_alloc` is thrown and since magisk is compiled with `-fno-exceptions`, it will crash the whole daemon process.

753808a4ce Also hijack plat_file_contexts if necessary 
Since Android 13, sepolicy are also loaded from APEX modules. Part
of the change is to run restorecon before SELinux is set to enforce.
In order to support this situation, we also hijack plat_file_contexts
if necessary to properly order our operations.

e841aab9e7 Add hijack sepolicy support for rootfs devices 
On older Android versions, pre-mounting selinuxfs will lead to errors,
so we have to use a different method to block init's control flow.
Since all devices that falls in this catagory must both:

1. Be Android 8.0 - 9.0
2. Have early mount fstab in its device tree

We can actually use the same FIFO trick, but this time not on selinuxfs,
but on the read-only device tree nodes in sysfs or procfs. By mocking
the fstab/compatible node in the device tree, we can block init when
it attempts to do early mount; at that point, we can then mock selinuxfs
as we normally would, successfully hijack and inject patched sepolicy.

49f259065d Introduce new sepolicy injection mechanism 
In the current implementation, Magisk will either have to recreate
all early mount implementation (for legacy SAR and rootfs devices) or
delegate early mount to first stage init (for 2SI devices) to access
required partitions for loading sepolicy. It then has to recreate the
split sepolicy loading implementation in-house, apply patches, then
dump the compiled + patched policies into monolithic format somewhere.
Finally, it patches the original init to force it to load the sepolicy
file we just created.

With the increasing complexity involved in early mount and split
sepolicy (there is even APEX module involved in the future!),
it is about time to rethink Magisk's sepolicy strategy as rebuilding
init's functionality is not scalable and easy to maintain.

In this commit, instead of building sepolicy ourselves, we mock
selinuxfs with FIFO files connected to a pre-init daemon, waiting
for the actual init process to directly write the sepolicy file into
MagiskInit. We then patch the file and load it into the kernel. Some
FIFO tricks has to be used to hijack the original init process's
control flow and prevent race conditions, details are directly in the
comments in code.

At the moment, only system-as-root (read-only root) support is added.
Support for legacy rootfs devices will come with a follow up commit.

810d27a618 Use /data as tmpfs mount point in 2SI setup 
Design credit to @yujincheng08
Close #5146. Fix #5491, fix #3752

Previously, Magisk changes the mount point from /system to /system_root
by patching fstab to prevent the original init from changing root.
The reason why we want to prevent the original init from switching the
root directory is because it will then be read-only, making patching
and injecting magiskinit into the boot chain difficult.

This commit (ab)uses the fact that the /data folder will never be part
of early mount (because it is handled very late in the boot by vold),
so that we can use it as the mount point of tmpfs to store files.

Some advantages of this method:

- No need to switch root manually
- No need to modify fstab, which significantly improves compatibility
  e.g. avoid hacks for weird devices like those using oplus.fstab,
  and avoid hacking init to bypass fstab in device trees
- Supports skip_mount.cfg
- Support DSU
