for android-10
This will support updating the ramdisk to a different
compression format and co-exist with magisk.
We are also cleaning up and removing non android-10
api makefile actions.
We are also moving twrp repacking to its own class. We
check the new ramdisk format and if it's different
we have magisk compress using the new ramdisk format.

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.
