kernel fscrypt doc: https://www.kernel.org/doc/html/v4.18/filesystems/fscrypt.html
This commit implements the ability for TWRP to use fscrypt to decrypt
files on the fscrypt implementation. It has been implemented mostly
in a new successor library to e4crypt called libtwrpfscrypt. Most of the
code was ported from AOSP vold.
Notable updates include:
- updated policy storage by libtar
- lookup of fbe policies by libtwrpfscrypt
- threaded keystore operations
Big thanks to Dees_Troy for the initial trailblazing
of encryption in TWRP.

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.
This patch allows items to have more than one action surrounded
by the <actions> tags like other GUI elements. The patch also
adds new twrp command line options that let you reload the theme
and switch to a specific page from the command line:
adb shell twrp reloadtheme
adb shell twrp changepage=advanced

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.

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.

I think this feature was used way back in the very early days of
TWRP 2.0 on the Kindle Fire and has not been used since. I see no
reason to keep it around for now and we can always reinstate it
later if for some reason we need this feature again.

On at least one device I've tested (htc msm8960), setting the
brightness after gr_init() is necessary for the splash to show.
Note that at this point in the boot process, the settings file has
not yet been read, so tw_brightness has its default value of max
brightness. When settings are finally loaded, the correct brightness
is loaded for the GUI.
Change-Id: Ifc58c1dc80ed9e6f6b2a269a9bb6764038626c84
Note: events.cpp is still old code renamed to cpp to make it
easier to call functions like gr_fb_width().
I had to modify AOSP fbdev code to provide a separate memory
surface for drawing to as drawing directly to the framebuffer
resulted in rendering taking about 5 times longer.
I also modified AOSP adf code to provide a separate memory surface
for drawing for the same performance reasons. The Nexus 9 supports
adf graphics.
Overlay graphics work on at least one device. Overlay provides a
separate memory buffer already so performance is good.
I do not have a drm device yet that I know of. I made some attempt
to update the drm code to determine the correct pixel format based
on the drm graphics format, but what is available in pixel flinger
and what is available in drm do not line up all that well. Reports
are that the Pixel C is using drm graphics, but performance is
slow, likely due to the use of a mmap instead of a memory buffyer.

For devices with an unusual aspect ratio, stretching a bitmap to
the screen resolution is sub-optimal. So let's reuse our XML engine
that allows assembling the splash screen from individual parts.
The splash page is loaded from a separate XML file for quick loading.

We should offer language selection on any start page such as
decrypt or system read only. However, if the mStartPage variable
was not being updated properly so selecting a different language
was dumping the user back on either the decrypt prompt or the
system read only page. This patch set fixes the problem and places
the user back on the proper page when they choose a new language.

This is similar to https://gerrit.omnirom.org/#/c/14014
A lot of the features built in the older patch set have been split
out into separate patches, most of which have already been merged.
The remaining functionality here should all be directly related to
language selection and loading. We always load English as a base
before loading other languages over the top of the base. The idea
is that if another language is missing a translation, then we will
still display the English.
Maybe still to do: read the /cache/recovery/last_locale file and
load a language based on that. For me, this file contains just:
en_US
We probably won't bother with region specific translations so we
would have to look at either trimming off the _US or using some
other method like perhaps a symlink or a combination of the two.
Thanks to _that for twmsg.cpp class

Reloading the GUI while the GUI is running and rendering is very
dangerous as we may be deleting GUI resources before or while we
are trying to render those same items. This change will allow us
to safely load new resources and delete the old ones.
Fixed a double free situation that was causing a crash on every
other theme reload.
Clear parsed xml documents when we are done loading the theme
instead of keeping them in memory for the life of the theme to
help save a little memory.
Store starting page so that if we request a reload, we can enter
the theme at the same starting point, which may come in handy if
we allow for language selection on alternate starting pages such
as the decrypt prompt or the system read only prompt.

This will significantly reduce theme maintainence and should be a
lot more sustainable over time. Eliminate most themes leaving only
5 remaining in 3 categores:
* watch_mdpi: 320x320
* portrait_mdpi: 480x800
* portrait_hdpi: 1080x1920
* landscape_mdpi: 800x480
* landscape_hdpi: 1920x1200
Add handling to map the old DEVICE RESOLUTION to the new TW_THEME
build flag. New devices should specify a theme using the new
TW_THEME build flag using one of the 5 values from the list above.
Long term we will eliminate the use of the DEVICE_RESOLUTION flag
in favor of the new flag.
Change the way sliders render so that they completely follow the
placement="5". This will probably break some custom themes but is
necessary so that we can retain the aspect ratio on slider images
and still have them rendered at the center of the screen.
Add code to the console slideout button so that it can be centered.
Centering the slideout button allows us to keep the button at the
center of the screen when retaining aspect ratios on the image.
Add more retain aspect ratios for home, back, slideout, folder,
file, and lock screen images.
Change the way we build the top bar in TWRP. It is now mostly
drawn using fill objects and the TWRP logo is a separate image so
that we can retain its aspect ratio during scaling. Thanks to Mark
Norelus for providing the TWRP logo.

With this patch set, if needed, we scale the images during early

These can be used to center a lower resolution theme onto a
higher resolution screen. May be useful for Nexus 9 unless or
until we decide to do a 1536x2048 theme or on devices like the
Moto 360 and LG G Watch R.
The build flags will only affect the stock theme. If a custom
theme wishes to apply an offset, it can be done by setting
tw_x_offset and / or tw_y_offset in the variables section of the
XML.

Allows sending openrecoveryscript commands to TWRP via shell.
This may be handy for visually impaired users, for various one
click utilities to drive TWRP commands from a computer, for using
TWRP when a catastrophic hardware failure like a shattered screen
prevents you from being able to use touch, or even on devices like

This patch also includes a few minor changes to openrecoveryscript
including proper support for rebooting via the script and for
decrypting the device via the command line.
