After we refactor the magic mount and always mount folder as tmpfs,
we can easily support deleting files or folders now. We recognize
dummy devices with major number 0 and minor number 0 as an indicator
for removing files and folders. This indicator is borrowed from
overlayfs.
For upgrading devices that continue to use Android 12 or older kernel versions, the generic ramdisk remains where it was with no requirement for a new init_boot image.
manager.sh + boot_patch.sh:
- all listed files from boot_patch.sh header are required for boot patching, but stub.apk was being removed so install_magisk via addon.d.sh would fail without it; leave it in place
addon.d.sh:
- remove old redundant recovery_actions call (it's also performed by setup_flashable in initialize)
- print ABI to match flash_script.sh output
boot_patch.sh:
- catch and abort on any errors from ramdisk.cpio patching in the future
util_functions.sh:
- fix hiding of mount_partitions /system_root umount stderr
- quote mount_apex .pb DEST name parsing charset for safety even though both work
Fixes#6828
For example, Lineage's com.android.ondevicepersonalization apex_manifest.pb has a # char, which strings keeps in its output, and breaks the mount for that apex before this fix
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.

- /system/bin/su was being removed in error from the live system so update remove_system_su to be aware of a running A/B OTA and generalize/simplify removal logic with relative paths to correctly run on the updated system slot
Fix topjohnwu#5013
When installing from recovery, previous implementation may select f2fs partitions to store sepolicy rules, but magiskinit won't mount them and unable to load sepolicy rules.
- ensure all scripts use $NVBASE $MAGISKBIN $POSTFSDATAD and $SERVICED where appropriate
- simplify new grep_cmdline() using xargs and more sed
- show correct active sepolicy $RULESDIR on devices with no encryption
- add support for Android 12 .capex (compressed apex) files
