92b305a389 Remove unnecessary mirror for magic mount
Mirror was previously used for accessing the original file during
magic mount when we are using a tmpfs to cover the target. However,
since we introduce atomic mount, we switch all tmpfs mount in
worker and then move to the target at once. It means that we can
still access the original file when we are constructing the tmpfs
mount point. Thus we no longer need mirror.

a8c2ae223a Avoid hexpatch /init for 2SI when possible
Previous we hexpatch /init from /system/bin/init to /data/magiskinit
to redirect the second stage init. However, some devices like sony
has /init that does not directly invoke /system/bin/init, and thus
the hexpatch fails.

In this patch, we further make use of AOSP `SwitchRoot` to help us
bind mount /data/magisk to /system/bin/init after `SwitchRoot`.

Two important assumption about 2SI are i) that the second stage init
is always /system/bin/init and ii) that the /sdcard (path after
`SwitchRoot`) is always a symlink to `/storage/self/primary`. When
these assumptions hold, during first stage init (before `SwitchRoot`)
we can bind mount magiskinit to /sdcard, and create a symlink
/storage/self/primary to /system/system/bin/init. By these steps,
during `SwitchRoot`, AOSP init will try to mount move /sdcard to
/system/sdcard. And /system/sdcard is symlink to /storage/self/primary,
it will try to mount move /sdcard to /storage/self/primary. And
/storage/self/primary in ramfs is now a symlink that points to
/system/system/bin/init, thus AOSP will try to mount move /sdcard
(which is a bind mount to magiskinit) to /system/system/bin/init.
After chroot done by AOSP init, we then have a magiskinit bind mount
on /system/bin/init, which is the second stage init.

An edge case is that some devices (like meizu) use 2SI but
does not switch root. In this case, they must already have a /sdcard
in the ramfs, thus we can check if /sdcard exists and fallback to
hexpatch.

eda8c70a80 Borrow value instead of moving in FsPath::from()
When accepting a value of AsRef<Utf8CStr> in FsPath::from(), the
existing code will move a value of Utf8CStrBufArr, creating a reference
that lives longer than the borrowing value, causing undefined behavior.

The issue is only visible on release builds, as more advanced
optimizations will be more aggressive re-using the stack of variables
that no longer lives.
