Adopted Storage support
-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.
