TARGET_HW_DISK_ENCRYPTION and TARGET_CRYPTFS_HW_PATH build flags
and related code in cryptfs.c are removed since it doesn't match
the driver in current tree.
To enable HW encryption, the driver needs to be hidlized.

We are investigating replacing make_ext4fs with the upstream tool mke2fs.
See b/23686092 for more informations.
To mitigate the trouble that may arise if the new tool behave differently
compared to the old one, there will be a transition period where both mke2fs
and make_ext4fs will be supported.
This patch does 3 things:
- add the necessary code to use mke2fs to format an ext4 partition;
- add a dependency to the binary used by vold.
Test: m -j32 with TARGET_USES_MKE2FS={,false,true}
TARGET_USERIMAGES_USE_EXT4={,true}

This replaces the libmincrypt dependency with libcrypto_utils, which
is needed due to libfec and fs_mgr switching to BoringSSL.

Give callers the option of preparing CE and/or DE storage. The
framework will only prepare CE storage after the CE keys have been
unlocked for that user.
When init is calling enablecrypto, kick off the work in a thread so
that we can make other calls back into vold without causing
deadlock. Leaves blocking call intact for framework callers.
Clean up 'vdc' tool to send useful transaction numbers, and
actually watch for the matching result to come back. This fixes
race conditions when there are multiple 'vdc' callers.
Also add other system and misc directories to match spec.

The key storage module didn't comply with Android coding standards
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!

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.

Refactor fstrim code to be encapsulated in unique task object, and
give it option of benchmarking when finished. Trimming now includes
both storage from fstab and adopted private volumes. Cleaner timing
stats are logged for each unique volume.
Add wakelock during ongoing async move tasks. Push disk sysfs path
to framework so it can parse any SD card registers as desired.

When formatting volumes, pass along fsType string which can be "auto"
to let the volume select the best choice. For now, private volumes
assume that MMC devices (like SD cards) are best off using f2fs when
both kernel support and tools are present, otherwise fall back to
ext4. Use blkid when mounting to pick the right set of tools.
Move filesystem utility methods into namespaces and place in separate
directory to be more organized.

In order to prevent this bug from happening, we must allow vold cryptfs
commands to complete while a long running mount is underway.
While waiting for vold to be changed to a binder interface, we will simply
create two listeners, one for cryptfs and one for everything else.

Now that we're offering to store private app data on adopted storage
devices, the performance of those devices is much more important to
overall user experience.
To help set user expectations, this change offers to execute a
real-world benchmark on a storage device, returning a metric that can
be used to compare internal and external storage. The benchmark is
generated from the strace-instrumented storage access patterns of
typical apps.
A typical device completes the benchmark in under two seconds on
internal storage, a UHS-3 SD card is even faster (!), but a very slow
Class 4 SD card takes about 30 seconds to complete, giving us a clear
signal.
The measured benchmark numbers are logged along with information
about the storage device, such as manufacturer, model, etc. Card
serial numbers are scrubbed from output.
