Added a new call change_user_key which changes the way that disk
encryption keys are protected; a key can now be protected with a
combination of an auth token and a secret which is a hashed password.
Both of these are passed to unlock_user_key.
This change introduces a security bug, b/26948053, which must be fixed
before we ship.

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.

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.

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

We now have separate methods for key creation/destruction and
unlocking/locking. Key unlocking can pass through an opaque token,
but it's left empty for now.
Extend user storage setup to also create system_ce and user_de
paths. Bring over some path generation logic from installd.
Use strong type checking on user arguments.
