and had room for improvemnet in a few other ways, so have cleaned up.

Instead of writing raw keys, encrypt the keys with keymaster. This
paves the way to protecting them with auth tokens and passwords later.
In addition, fold in the hash of a 16k file into their encryption, to
ensure secure deletion works properly.
Now even C++ier!

As a precaution, we do the work of emulating an unlock even on devices
that aren't emulating FBE. However, we don't care if it fails, so
don't fail the calling command in that instance.

Major rework and refactor of FBE code to load the keys at the right
time and in a natural way. The old code was aimed at our goals for M,
with patches on top, and didn't quite work.

* commit '9b5db9bcbe333b677ca18d2c1c398c8751cd0fd2':
cryptfs: Skip to encrtypt unused blocks into a block group which uninitialize block bitmap .
Much nicer C++ style logging, but the main reason is to clean up
AutoCloseFD.h so I don't have to use cutils to use it.

After DocumentsProvider opens FD on app fuse, DocumentProvider passes it
to other applications. To allow other applications to use the FD on app
fuse, we need to specify allow_other mount option.

If storage is not visible to apps and no need to spin up FUSE, it also
should not make FUSE mount point directory.

Add the serial parameter to prepare_user_storage to avoid
confusion when parsing parameters and passing them around.

When FBE emulation is enabled, lock/unlock the media directories that
store emulated SD card contents.
Change unlocking logic to always chmod directories back to known
state so that we can recover devices that have disabled FBE
emulation.

Change encryption to happen after a reboot, not before. This
removes the problem whereby if data cannot be unmounted, we cannot
encrypt.
