b7f0702ea6 DO NOT MERGE Use default key permissions for ext4enc 
(cherry-picked from commit 1190a26f6d)

As per discussion default permissions are the correct ones.
Note that since we use logon keys, they cannot be read outside
the kernel.

Note also that we limit who can read/write keys in selinux policy.

731a7a242d DO NOT MERGE Securely encrypt the master key 
(cherry-picked from commit 707fd6c7cc)

Move all key management into vold
Reuse vold's existing key management through the crypto footer
to manage the device wide keys.

Use ro.crypto.type flag to determine crypto type, which prevents
any issues when running in block encrypted mode, as well as speeding
up boot in block or no encryption.

This is one of four changes to enable this functionality:
