fscrypt aosp doc: https://source.android.com/security/encryption/file-based 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.
