* The dm-crypt device needs to be removed from
the device-mapper driver list otherwise it will
remain busy and cannot be used later on by
other processes (eg vold_decrypt) or for further
testing/debugging in recovery.

- Breaks decryption on some hw_crypto devices
- Default value already defined in preceding ifdef
- PS2: Move crypt_params definition prior to ifdef
(matches corresponding code from CAF)
Huge thanks to @beaups for figuring out the issue!

I am not sure if we are really fixing anything other than we are
allowing the decrypt process to continue. On hardware crypto the
password never seems to match what is expected from the data in
the footer, probably because the data is not stored in the footer
and TZ does all the work. Still, if it works, it is hard to fault
the patch.

Some of the convoluted convert_hex_ascii_to_key code is needed to
properly decrypt CM 12.1 patterns where grid size is larger than
3x3.

- Don't upgrade HW encrypted Lollipop devices to Marshmallow crypto
- Fix support for passwords and patterns with an odd number of elements
- Remove unused code
- Fix build warnings

-Detects, decrypts, and mounts an adopted SD card if a
secondary block device is defined (usually mmcblk1)
-Handles unified storage
-Displays the adopted storage in MTP along with internal
-Factory Reset - wiped just like a data media device, we
retain the keys folder and the storage.xml during a
factory reset
-Backup / Restore
-Disable mass storage when adopted storage is present
-Read storage nickname from storage.xml and apply it to
display names in the GUI
-Read storage.xml and determine what storage location is in
use for /sdcard and remap accordingly
libgpt_twrp is source code mostly kanged from an efimanager
project. It is GPL v2 or higher, so we will opt for GPL v3.

In order to maintain compatibility with older trees, we now have
minadbd.old and minui.old. I had to use a TARGET_GLOBAL_CFLAG to
handle ifdef issues in minui/minui.d because healthd includes
minui/minui.h and there was no other alternative to make minui.h
compatible with older trees without having to modify healthd rules
which is outside of TWRP.
Note that the new minui does not currently have support for qcom
overlay graphics. Support for this graphics mode will likely be
added in a later patch set. If you are building in a 6.0 tree and
have a device that needs qcom overlay graphics, be warned, as off
mode charging may not work properly. A dead battery in this case
could potentially brick your device if it is unable to charge as
healthd handles charging duties.
Update rules for building toolbox and add rules for making toybox
Use permissive.sh in init.rc which will follow symlinks so we do
not have to worry about what binary is supplying the setenforce
functionality (toolbox, toybox, or busybox).
Fix a few warnings in the main recovery binary source code.
Fix a few includes that were missing that prevented compiling in
6.0

With 5.0 L, we decrypt automatically if the default_password is
used. Non datamedia devices do not get the format data button so
they cannot wipe encryption off the device. This patch add a wipe
encryption button where the format data button would normally be
located on the Wipe page.
This patch also attempts to remove / delete the dm-crypt block
device before formatting.

Some of these fixes needed to be made anyway. Note that older
trees will still need to have files / repos copied into them from
newer trees. Namely we need:
system/security/softkeymaster
hardware/libhardware/include/hardware/keymaster.h
Maybe others as I did not document very carefully what I was
pulling in.

Trim cryptfs.c to remove functions that TWRP does not use for
decrypt and remove the need for libfs_mgr from cryptfs.c by
passing some items to cryptfs.c from the partition manager.
Add support for new fstab flags:
encryptable and forceencrypt=/path/to/cryptokey
For example:
flags=forceencrypt=/dev/block/platform/sdhci-tegra.3/by-name/MD1
Note that "footer" is the default, so you do not need to set this
flag on devices that use the footer for the crypto key.
Also add mounttodecrypt if you need to mount a partition during
the decrypt cycle for firmware of proprietary libs.
Clean up decrypt and only support one version
Android 5.0 lollipop decrypt should be backwards compatible with
older versions so we will only support one version, 1.3 that came
with 5.0 lollipop.
Remove support for Samsung TouchWiz decrypt. It does not work with
the latest versions of Samsung encryption anyway and it has not
been updated to work with any AOSP decryption higher than 1.1

Mount the vendor partition if it exists so we can use any
proprietary files we may need.
Relocate auto decrypt when default_password is in use to after all
partitions are added so that we can mount the vendor partition.

Kang in cryptfs.c and cryptfs.h from vold.
Use TW_INCLUDE_L_CRYPTO := true to enable.
Ramdisk must contain the normal fstab file in the root in the
usual format of:
fstab.{ro.hardware}
For examble for Nexus 5:
fstab.hammerhead
Or on many Qualcomm devices:
fstab.qcom
Tested against Android 5.0 lollipop on Nexus 7 2012 grouper. Not
sure if or how this will work when we are dealing with a device
with a hardware keystore. Long term we need to add a GUI element
to allow entering a pattern. For now you can decrypt a pattern
unlock by converting the dots to numbers in the following format:
123
456
789
So an upper-case L would translate to 14789 as a password entered
on the keyboard.
