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.

* Revert: Make legacy props an option disabled by default
  (reverted from commit 75aa6157)

* Instead check for ANDROID_PROPERTY_WORKSPACE in the updater-
  binary to determine whether legacy property service can be
  used

* OmniROM 8.0 uses AOSP f2fs-tools which builds a static
  mkfs.f2fs directly to $(TARGET_RECOVERY_ROOT_OUT)/sbin

* 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
      ]
