for android-10
This will support updating the ramdisk to a different
compression format and co-exist with magisk.
We are also cleaning up and removing non android-10
api makefile actions.
We are also moving twrp repacking to its own class. We
check the new ramdisk format and if it's different
we have magisk compress using the new ramdisk format.

This allows flame to boot TWRP. Still will need to work on
super partition for vendor and system access.
The plan will be to cherry-pick any updates to android-9.0
through gerrit.twrp.me to this branch as a WIP.
Add debug capability.
Fix backup of images after tarred partitions with too much padding
Add more md5 logging.
Skip digest check if selected.
Change ADB Backup version to 3 for new fixes to image padding.

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>

This patch is to refactor twrpDigest using polymorphism
and inheritance to use the same call patterns for creating and
reading a digest. Now a library.
Use SHA2 from libcrypto. SHA2 is default if device has libcrypto.
Change string MD5 everywhere to use digest or Digest instead. Updated
string tags to digest. Translation will be required.
Switch out digest code into a driver class from partitionmanager.
SHA2 is better for digest creation due to decreased collision space
compared to MD5 and SHA1.

This will allow the gzip compression header to be
written properly to the adb stream.
Thanks to nkk71 for finding the issue.

There were a few memory errors while restoring a backup via adb (created
using `adb backup --twrp`).
On my device (S5 mini) it resulted in this error message:
FORTIFY: strlen: prevented read past end of buffer
This commit fixes this issue and a few other potential issues.

Set Backup_FileName on adb backup to fix restore.
Set read_from_adb after EOF to return properly
from newer adb client prompt.
Create setter and getter for Backup_FileName
for openrecoveryscript.cpp which is not a
friend class.
Fix condition for twrpTar::Get_Size() and adb backup.

Functionality for client side to backup
tar and image streams over adbd to the client under backup.ab.
Using adb backup on the client side you can backup the partitions
TWRP knows about.
On the client side you can do the following:
adb backup -f <filename> --twrp <options> where options are
--compress: compress data
system: backup system
cache: backup cache
data: backup data
boot: backup boot
etc for each partition.
You can string multiple options,
i.e. adb backup -f <filename> --twrp --compress cache system data
adb backup in TWRP will take any option corresponding
to TWRP fstab partitions, e.g. efs boot as well.
If you do not specify the filename with the -f option,
adb will backup your data to a filename backup.ab on the client.
You can then rename the file and encrypt it with desktop tools.
If you don't want to use command line arguments:
adb backup --twrp
will bring up the gui and allow you to choose partitions
from the backup page.
To restore the backup use the following convention:
adb restore <filename>
Structures are used to store metadata in binary inside
of the file itself. If the metadata structure is modified,
update the adb version so that it will invalidate older
backups and not cause issues on restore. When restoring,
we currently do not support picking specific partitions.
It's all or nothing.
