* Set proper SELinux context for system-as-root system, AOSP uses "/"
in fstab while TWRP uses "/system_root" so an exception is necessary.
* Skip initializing context if the target partition doesn't exist in
/file_contexts e.g. /usb-otg.

* Otherwise no context will be initialized but existing context will be
erased and lead to unexpected behavior, e.g., device no longer boots
after restoring a system backup due to missing valid seclabel of the
system partition.

Easiest way I could find to determine if we have the old or the
new mkfs.f2fs version is to pipe the usage output to grep and
grep the output for "reserved" and redirect the output to a file.
If the file has any data in it, then we must have the old
mkfs.f2fs that uses -r.

* For EXT2/3:
* Align mke2fs options with Android 9.0 fs_mgr_format.cpp.
* For EXT4:
* Note that make_ext4fs is still in use on Android 8.1 to workaround
a FDE encryption bug even though mke2fs has become the default
choice. The bug is fixed in Android 9.0+.
* For F2FS:
* Drop the broken "-r" option, it's never ported to O, explicitly
pass number of sectors instead.
* Keep all options aligned with Pie fs_mgr.
* Check existence before start wiping, as Wipe_EXT4 does.
* For all:
* Calculate block size at runtime, and reserve the space specified
via negative "length" option from fstab. Note that positive length
will be ignored.
* If the partition has crypto footer, and "length" is not specified
in fstab, automatically reverse CRYPT_FOOTER_OFFSET (16384).
* Remove the default crypto key location: footer, this is a bad
assumption since most partitions don't use encryption! We need to
know the real situation to decide whether to reserve crypto footer
on format.
* If the current action is "wipe" or "change filesystem", wipe crypto
footer or block device after mkfs if the partition is
unencrypted or undecrypted (e.g., wrong password).
* If the current action is "format data", unconditionally wipe crypto
footer or block device.

Building in 9.0 may require you to add a flag to your twrp fstab
with the fileencryption details like:
fileencryption=ice:aes-256-heh
Verify this against your device's stock fstab of course.

* /persist can be mounted early while TWRP is parsing the fstab so
as soon as the partition is parsed, mount and adjust the time
accordingly.
* Store a backup settings file on /persist. Having a 2nd copy of
the settings file in the /persist partition allows for early
reading of the file and adjust timezone and brightness to user
preference while still on TWRP splash.
* Add the qcom ats time offset in TWRP settings file and use it
if no better ats file is found. This will also allow devices
with a persist partition, but no ats files in it, to adjust
the time offset during early boot.
* Use /persist/time/ as Qualcomm time fix source, based on

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.

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.

-Change backup display name to say that we are excluding storage
-Add warning message during backup of any partition with data media
-Also eliminate unused variable from twrpTar class
Maybe this will make the people in issue 276 happy, but probably not because
they already lost their data, or because the warning text is yellow instead of
red.

The PartitionSettings struct contains some data elements that are duplicates
of data elements in the TWPartition class that is contained within the
PartitionsSettings.Part element. We will eliminate this duplication to help

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.

The necessity to process fstab twice stems from mounting partitions
while still processing. Instead, wait to finish setup of /data, /cache
and storage parameters until after fstab has been processed (once).
