Secure block discard/trim was fixed by:
https://github.com/CyanogenMod/android_external_f2fs-tools/commit/6b39b93d83ab4ccb1913ecbc7a5a3e16766a011f

Once fixed, formatting using discard/trim takes a LONG time.  Other TWRP
formatting methods are already insecure.  It doesn't make sense for this
one type of partition to have secure wipe when none of the others do.

Chances are there are not many themes in widespread use that are
using jpeg images, but this will be easy to revert back or even
just temporarily modify if we need jpeg support in a pinch.

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.

libgpt_twrp is source code mostly kanged from an efimanager
project. It is GPL v2 or higher, so we will opt for GPL v3.

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.

Additional patch by: Matt Mower
Replace clunky /nobrightness handling

Cleanup TWFunc::Set_Brightness() and blanktimer::getBrightness() a
bit, primarily for the purpose of relying on the value in
tw_has_brightnesss_file instead of checking for a phony brightness
path.

normal zip limit is 4GB, but due to signed variables it will only
access 2GB (32bit signed integer is from -2GB to +2GB).

these changes allow for a theoretical limit of 4GB zips to be flashed.
RAM restrictions still apply, and on a 32bit system it's likely to max
out at approx 2.8GB flashable zip, above that mmap will probably fail.

Note: the flashable zip also needs a compatible update-binary which
include these changes.
(this also applies to both aroma installer if it's being used).

* Find and rename/remove duplicate string variable names
* Add missing string variables to en language file
* Fix display of some strings missing @ in front of variable name
* Fix several %s --> {1}
* Be consistent in usage of cancelled vs. canceled (both spellings
  acceptable)

Tip for finding strings missing from language files:

1) Find all messages:
egrep -hr "gui_msg.+=" > /tmp/msgs.txt

2) Regex replace to trim them down
WHAT: ^\s+gui_msg(?:[^"]+)"([a-zA-Z0-9_]+)=([^"]+).+
WITH: $1
Note that $2 can be used to retain the message

3) Find missing strings:
for i in $(cat /tmp/msgs.txt); do
    if ! grep -q $i gui/theme/common/languages/en.xml; then
        echo $i;
    fi
done

Main goal of this patch is to improve error handling when a custom
theme does not contain a valid theme version. We were getting a
message saying that the theme_ver_err resource did not exist as
well as an error saying that the package had failed to load. Now
we properly get a single error message about the theme version.

Add a themeversion value to the ui.xml details section. Check this
value against a define during early theme loading. If we are
loading a custom theme, then reject the custom theme if the
version does not match (or not defined) and load the stock theme.
If it is the stock theme, show a warning but continue loading.

Also fix an issue with changing overlays. Not sure how it ever
worked before, but it works now.

TLDR: Use the stock theme if the custom theme version does not
match.

-Improve code for partitioning sdcards
-Allow user to select a device for partitioning (must be removable)
-Use sgdisk to partition sdcards
-Set default sizes for ext and swap to 0
-Change increments for ext to 256MB and swap to 64MB

Note: sgdisk is included in 6.0. I have included a static prebuilt
sgdisk for trees that do not have sgdisk, however the prebuilt
sgdisk is a decent bit larger than the old parted binary. The old
parted binary is quite old at this point and we only have it for
armv7a. sgdisk should be maintained by AOSP and can be built from
source so it should work across architectures.
