We can clearly see that after version 3 script is executed with
its specific functions. It cannot or don't unmount partitions for
successful OTA upgrade. Resulting broken installation, this also
affects ROM inbuilt OTA updater app.

* Ignore the block devices in case their mount points are symlinks.
This is common on devices where maintainers have chosen not to use
real partitions because of their size being too small to be useful
Also `continue` instead of `break`. Oops.

* The plan was to support odm & oem too, but it turned out
unnecessarily complicated due to their symlink setup,
while being most likely unused.
The partitions were removed from the list of supported ones
in a-only backuptool, but were forgotten in ab backuptool.

For scripts declaring ADDOND_VERSION=3 automatically mount
vendor, product, system_ext and others (when they're dedicated partitions).
Also expose the get_output_path() function to get the path to where
a file is mounted in case it lives in a dedicated partition.
ab exapmles:
get_output_path "system/product/priv-app/MyApp.apk" = "/postinstall/product/priv-app/MyApk.apk"
get_output_path "system/app/MySystemApp.apk" = "/postinstall/system/app/MySystemApp.apk"
a-only examples:
get_output_path "/mnt/system/system/product/priv-app/MyApp.apk" = "/mnt/system/system/product/priv-app/MyApp.apk"
******************************************************************
Instead of cycling all scripts for each stage, run
pre-backup -> backup -> post-backup in quick succession
(and likewise for restore), to ensure backwards compatibility
with scripts that wrongly assumed their environment not to
change between steps.
This is needed because we want to undo any mounting done for V3
scripts when executing V2 scripts. If a V2 script did mounting in
pre-restore and expected things to still be mounted in restore,
we would break their (yes incorrect) assumption.

Backup/restore functionality was broken in the
Ia1f4ae95c9e4dae4df844853e81c264bc838f177 change
because of incorrect check of the function's result.
check_prereq() function refactored to return 0 if
backuping/restoration is possible. Any work should be
performed only if check_prereq() succeeds.
Change-Id: Ic977dba675df58a228ef4b882b25beb66cc9d2c6
For non AB devices system partition should be unmounted
if check_prereq function fails.
This patch also refactors backuptool a bit for AB devices
in order to look same as backuptool for non AB devices.

* The LineageOS versions properties were removed from the build.prop,
which is resolved properly in commit:
"lineage: Keep LineageOS versions properties in build.prop"

* 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.

* A/B OTA devices wont run backuptools in recovery (because they don't
go in to recovery to do an OTA). In these cases let's use a modified
version to backup/restore from within android upon postinstall.
* Add backuptool_postinstall.sh which will be run prior to the normal
postinstall script in order to backup/restore via addon.d scripts.
* This needs to be done in such a manner because we need /postinstall
mounted rw instead of the ro with context= options which are used for
the normal postinstall (dexopt) script.
