Test: mma, marlin/angler boot

Keymaster but in-process crypto.
Bug: 33384925
Test: manual for now: patch KeyAuthentication.usesKeymaster() to always return true;
flash a FBE device, add a device PIN, reboot and verify PIN can unlock FBE.
Then clear device PIN, reboot and verify FBE is unlocked automatically.
In both cases, check there is no keymaster_key_blob in
/data/misc/vold/user_keys/ce/0/current/
Unit tests to be added.

Don't rely on cryptographic binding of secdiscard to key; securely
delete the other information needed to reconstruct the key too.

Avoid a timeout error by extending the time allowed between getting
the auth token and decrypting the key from five to thirty seconds.

The formatting here is inconsistent with Android house style; use
clang-format to bring it back into line.

Google/Android C++ style requires that arguments passed in for writing
should be pointers, not references, so that it's visible in the caller
that they'll be written to.

A bug meant that the auth token wasn't being used; it turns out that
in order to use it we need to do things slightly differently.

- catch errors in looking for the keyring
- static_assert to prevent a buffer overrun
- remove obsolete, misleading comment
- dial down priority of some log messages
- explain why we ignore some errors
- idiomatic C++11
Bug: 27552432

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.

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!
