`ro.build.ab_update` is being moved from /system/build.prop to
/vendor/build.prop. This CL allows init to keep exposing the value as a
system property.
init: Do not have permissions to set 'ro.build.ab_update' to 'true' in property file '/vendor/build.prop': SELinux permission check failed
Bug: 130516531
Test: Build and flash crosshatch-userdebug. Check /system/build.prop,
/vendor/build.prop and the runtime property.

mediaserver uses libaudioclient (via libmediaplayerservice).
The code in libaudioclient may access IAudioManager.
For that, mediaserver has to be allowed to find "audio" service.

To install GSIs on external storage (such as sdcards), gsid needs some
additional privileges:
- proc_cmdline and device-tree access to call ReadDefaultFstab().
This is ultimately used to check whether system's dm-verity has
check_at_most_once enabled, which is disallowed with sdcards.
- vfat read/write access to write files to the sdcard. Note that
adopted sdcards are not supported here.
- read access to the sdcard block device. To enable this without
providing access to vold_block_device, a new sdcard_block_device
label was added. Devices must apply this label appropriately to
enable gsid access.
- FIBMAP access for VFAT filesystems, as they do not support FIEMAP.
This only appears to work by granting SYS_RAWIO.

fsverity_init is a new shell script that uses mini-keyctl for the actual
key loading. Given the plan to implement keyctl in toybox, we label
mini-keyctl as u:object_r:toolbox_exec:s0.
This gives us two benefits:
- Better compatibility to keyctl(1), which doesn't have "dadd"
- Pave the way to specify key's security labels, since keyctl(1)
doesn't support, and we want to avoid adding incompatible option.
Test: Boot without SELinux denial
Test: After boot, see the key in /product loaded

This is the type used on super partition block devices.
- On devices launch with DAP, super is already marked
as super_block_device_type.
- On retrofit devices, appropriate block devices must
be marked as super_block_device_type, for example:
typeattribute system_block_device super_block_device_type;

These denials occur on boot when android_get_control_file also
changes from readlink() to realpath(), because realpath() will
lstat() the given path.
Some other domains (fastbootd, update_engine, etc.) also uses
libcutils to write to kernel log, where android_get_control_file()
is invoked, hence getattr is added to them as well.
