Recent devices (e.g. Pixel 2XL aka taimen) do not define any "system"
partition in their fstab, so a plain "mount /system" fails.
Furthermore, trying to get the entry from /etc/recovery.fstab also fails
because the partitions have slot suffixes (e.g. system_a).
So for these devices, we need to figure out the active slot, mount the
system partition (which really contains the whole root) and lastly mount
the actual system partition from the rootfs.

* Since A/B addon.d scripts are going to need to do things in a
specific way or things could go horribly wrong for a user, let's
introduce versioning so that scripts can claim to be compatible.
* A script can denote it is compatible with addon.d version 2 by
adding: "# ADDOND_VERSION=2" somewhere in its script.
* Only A/B will require version 2 scripts for now, and version 2
scripts will still run on non-A/B. Additionally if a script does
not explicitly denote its version, assume its version 1.
* Version 1: The same old scripts we've always used. We cannot assume
these will all work with A/B backuptools.
* Version 2: Scripts that denote they are compatible with version 2
must be aware of the fact that A/B devices will run this
script for a rom, during a seamless update, mounted at
/postinstall. The best way to ensure compatibility would
be to use the pre-designated functions found in the
backuptool[,_ab].functions scripts.

Run 'make addonsu' to make a flashable zip to install the addon and
'make addonsu-remove' for a flashable zip that removes it.
