This release fixes restore by forcing regular TWRP Backup by default.
Thanks to jlask for fixing this issue.

* In omni-8.0 'android.hidl.base@1.0.so', although properly built
does not get copied to the /sbin/ directory for TWRP, resulting
in TWRP constantly *trying* to restart with the missing lib:
CANNOT LINK EXECUTABLE "/sbin/recovery":
library "android.hidl.base@1.0.so" not found
Leading to a stuck on "black" screen (or some splash screen, but
never even reaching TWRP splash screen).

* HTC U11 Oreo is using keymaster3 FDE encryption which requires
the new services:
1- /system/bin/hwservicemanager
2- /vendor/bin/hw/android.hardware.keymaster@3.0-service
3- /vendor/bin/qseecomd (instead of /system/bin/qseecomd)
So in addition to /vendor/lib and /vendor/lib64 also
symlink /system/vendor/bin to /vendor/bin.
* vold_decrypt services now have separate prefixes:
1- 'sys_' referring to /system/bin
2- 'ven_' referring to /vendor/bin
* The additional (hwservicemanager, keymaster-3-0) and modified
(qseecomd) .rc files have been updated in the vold_decrypt
directory.
Comments were added directly in the .rc files, please check
them.
* /etc/recovery.fstab needs to be temporarily moved since
vold will use it if it finds the '/sbin/recovery' file
(refer to fs_mgr for the fstab load code https://goo.gl/8KaZyf).
Since fs_mgr cannot parse TWRP style fstab, we 'hide' it
and attempt to create a symlink to /fstab.{ro.hardware}.
Also remove shell dependencies, code cleanup, new error codes:
* Critical sections of vold_decrypt should not rely on the external
shell (and the available binaries) provided by TWFunc::Exec_Cmd.
Doing so may lead to failures resulting from different shell
provided binaries not working properly, especially since busybox
can be inconsistent across different trees.
In particular the following functions have been changed:
* run_vdc() no longer uses daisy chained commands, instead
it now forks and executes vdc directly including a 30 second
built in timeout.
* Symlink_Firmware_Files() no longer relies on the shell 'find'
command to retrieve the list of firmware/vendor files and instead
uses a built in function, Find_Firmware_Files(), which traverses
the system partition to retrieve the list of files.
* The code has also been cleaned up a little for better consistency,
and vold_decrypt will now return various error codes for the
different failures, as defined in vold_decrypt.h, which allows the
gui_msg to be moved back to partitionmanager.cpp.
Notes regarding pre Android 8.0 builds:
* Service names in .rc files cannot exceed 16 characters (including
the prepended 'sys_' or 'ven_') in Android 7.1 and below, so a
service name such as 'sys_hwservicemanager' is out of the question
for 7.1 and below.
* hwservicemanager will check ACLs on 'hwservicemanager' and 'ITokenManager'
if they are even allowed to run, otherwise the interfaces will fail.
The policies have only been introduced in 8.0, and although it is possible
to manually add them to the 7.1 policies it's not recommended.
* Therefore the best course of action is to build in 8.0.
* SIDE NOTE: On the HTC U11 we are actually using omni-7.1 with some changes
in the device tree to support both Nougat and Oreo decryption, please
refer to:
1- https://gerrit.twrp.me/c/2756/ for the necessary sepolicy and
BoardConfig changes.
2- The Android.mk file for vold_decrypt was modified to truncate
greater than 16 character service names (as mentioned therein)
Other changes:
* TW_CRYPTO_SYSTEM_VOLD_DISABLE_TIMEOUT is now deprecated due to built-
in fork and timeout.
* Output_dmesg_to_recovery_log() is also deprecated so upon a failed
decryption the recovery.log will no longer append it, instead you can
just use 'adb shell dmesg' to check it. Nonetheless if a true debug
build is needed use the original TW_CRYPTO_SYSTEM_VOLD_DEBUG flag as
outlined in the original commit message (see below).

Includes various minor fixes for building in Android 8 trees with r23+ tag
Update FBE extended header in libtar to version 2 and include the entire
ext4_encryption_policy structure now after translating the policy.

Auto detect and support both the v1 and v2 fstab formats
Support putting TWRP style flags in a separate /etc/twrp.flags file
twrp.flags format is the same as twrp.fstab (v1 with TWRP flags)
Support using a wildcard in a block device and find all partitions:
/usb-otg vfat /dev/block/sda*
Support using sysfs entries (voldmanaged) and read uevents and scan for
wildcard partitions from uevent data. (twvold?)
May not be complete for some of the newer flags found in fstabs in newer
build trees and there is a slim chance of a crash if the user removes a
removable device while TWRP is performing actions. May need to add some
kind of mutex to prevent the 2 threads from causing this crash. We need
to start somewhere though and this change is pretty innocuous when not
using a v2 fstab.

Restore adb backup files that TWRP made to your PC.
Put files in your backup directory to see them.
e.g. /sdcard/TWRP/BACKUPS/<sn>

* Revert: Make legacy props an option disabled by default
(reverted from commit 75aa615767)
* Instead check for ANDROID_PROPERTY_WORKSPACE in the updater-
binary to determine whether legacy property service can be
used

* When you format the system partition, it will remain
in a mounted state.
* Subsequently restoring a system_image (even though
successfully) the Update_System_Details() function
will not correctly update the system partition
details.
* Reproducible by:
1- Advanced wipe: System
2- Restore: System_Image
3- Reboot -> No OS prompt
* eg: [
~ # twrp get tw_min_system
tw_min_system = 50
~ # twrp get tw_backup_system_size
tw_backup_system_size = 8
~ # mount -o ro /system
~ # du -sh /system
3.5G /system

'group_range_count' doesn't properly consider the pair-wise range
structure. It may split the ranges into wrong pairs if it evaluates to
an odd number.
For example, for an input range string of "6,0,2,10,12,20,22" with 4
threads, group_range_count becomes 1. It would then try to verify (0,2),
(2,10), (10,12) and (12,20). Note that (2,10) and (12,20) are not valid
ranges to be verified, and with (20,22) uncovered.
Bug: 68343761
Test: Trigger update_verifier verification. Check the number of verified
blocks against the one in care_map.txt.

(cherry picked from commit 559a6d1d2a)
Prior to this CL, menu_ is allocated with a fixed length of text_rows_.
However, because we support scrollable menu in wear_ui, there might be
more menu entries than text_rows_, which would lead to out-of-bounds
array access. This CL addresses the issue by switching to std::vector.
Bug: 65416558
Test: Run 'View recovery logs' on angler.
Test: Set large margin height that leaves text_rows less than 21. Then
run 'View recovery logs' with 21 menu entries.
