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.

* This check was supposed to check whether the script
addon.d version was lower than backuptool's
* Given that the backuptool addon.d version is 1, this
isn't going to happen ever making this check completely
unuseful

* For some odd reasons executing `cd /system/addon.d` makes the system
hang and unmount error:
umount: /system_root: Device or resource busy
* Don't change directory to not allow the system partition hang

* If any of these two function gets run on a recovery mounting system
to /system, /system/addon.d won't exist while /system/system/addon.d will.
* Run the functions with $S as argument to make this work correctly

* The path /postinstall exists only for A/B, causing:
grep: /postinstall/tmp/addon.d/*sh: No such file or directory
Change-Id: Ia07b3029e949c3e08302457cd08798a4dde00ef6
* Dynamically mount system to the path chosen by the recovery through backuptool
* This can be helpful because of the fragmentation that will happen with system mount in recovery after Q

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

* The grep errorlevel output was not properly used by the if,
therefore allowing a device to upgrade with old addons
instead of aborting the backuptool steps
* The LineageOS versions properties were removed from the build.prop,
which is resolved properly in commit:
"lineage: Keep LineageOS versions properties in build.prop"

* otasigcheck doesn't work on encrypted devices and makes
the zip installation fail since oreo.
* The build part of this was never ported to oreo.
This reverts commit aff5e54c4e.

* 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.

* Due to both following commits, backuptool went permissive
and lineage properties got lost from the system on devices
that do not have BOARD_PROPERTY_OVERRIDES_SPLIT_ENABLED

* Once the properties issue is properly resolved in the sources,
a period of time is required for "most" of the users to upgrade
their system with fixed lineage properties before we break addons
by repairing the backuptool script globally

* System default props defined using PRODUCT_SYSTEM_DEFAULT_PROPERTIES
are stored into /system/etc/prop.default, so that's the location where
ro.lineage.version prop needs to be checked now. Although, fallback
to the old location to allow sucessful upgrades.

If /system is empty, /tmp/addon.d/ will not exist, "*sh" won't be
expanded, md5sum will not generate any output and the variable $s
will be empty. Therefore grep, which will receive only one arg, will
start to read the standard input and never exit, causing the
installation to never end. Fix this checking whether we have files
to read or not.

Add a function that allows to copy files preserving their SELinux
context that is generic enough to work with both busybox and toybox.

We should not test symlinks using -e or -f, otherwise the order in
which the files are backed up and restored matters.
Change-Id: I9b87972b27a63ef562c0c5f46f943eafd0a08ce1
* Add the addon.d folder creation to preserve_addon_d
before copying the files back to /system/addon.d
* On CM based ROMs, the path exists for built elements,
but on other AOSP-based ROMs where this script might
be used, the folder might not be created on build and
copy fails, breaking backuptool on second ROM update

Shells based on busybox, such as found in CM 12.1 recovery and TWRP, do not
properly handle pattern based parameter expansion for variables longer than
4kb. This throws our naive little XML parser into an infinite loop. Since
all such lines are associated with external app certs, just skip them.
Change-Id: I203b65c1ffd62bf3261b3ae315327314a5006952
Rewrite the packages.xml parser to be slightly less brittle. Read
lines from packages.xml and save off the interesting values, then
compare with expected results afterward.
This both avoids using grep's -A option, which is not supported in
toybox, and allows the script to recognize the cert tag regardless
of its position inside the package tag.

* Lots of stuff in the wild actually uses wget, and Toybox doesn't
provide it. We already have Curl which does the same thing just
with some different arguments. This wrapper script can handle it.

If the --wipe_data command is being passed to recovery, skip the
signature check since the data will be wiped after the update is
installed
