Add the force_and_revert option to the unmount command which will force
the unmount, and revert a crypto mapping.  This is used during factory
reset so that when the internal sdcard volume is formatted, it formats
the raw device, not the encrypted mapping.

Bug 3384231 is punted to MR1, but the code to set the flag is already
in the tree, so this CL does 3 things:

1.  Comments out the lines that set the flag
2.  Removes the change to the checkpw that was added in the last change.
3.  Implements a new command to check the flag (which no one is calling
    yet and the flag won't be set anyhow).

When MR1 comes, it will be a simple matter to enable the flag setting
code and start testing it.

The fear is a false positive detection of incomplete encryption could
cause people to be prompted to wipe their data when MR1 comes out and
the flag is checked.  Not setting this for first release, and testing
this more before MR1, will give us confidence that the code will not
detect false positives of encryption failure.

The master key is now stored unhashed in memory. This
is needed because certain operation like remote reseting
of passwords the old password is not avaliable.
The changepw interface has been changed to only take
the new password as the only argument. When this is
called we reencrypt the master key with the new password
and old salt.

The caller will check the result code for success. This prevents a exception from being thrown when the result code needs to be propagated to the caller.

Update the enable inplace API to allow the UI to show a progress bar.
Add new command changepw (whichis currently not working)
Internal restructuring of code to support these two features.
Some minor cleanup of the code as well.

In order to make the animations and the UI look right, we need to change
the cryptfs checkpw command to return a status if the password was
correct or not, and not have it automatically restart if it's correct.

There is a new command restart that will restart the framework with the
encrypted filesystem.

There are still a few hacks and performance issues related
to shutting down the framework in this code, but it is
functional and tested.  Without the UI changes, it requires
cryptic adb shell commands to enable, which I shall not
utter here.

* Rename all functions dealing with OBB files to mention Obb

* Add 'path' and 'list' functionality to OBB commands

* Store hashed filename in loop's lo_crypt_name and keep lo_file_name
  for the real source filename. That way we can recover it later with an
  ioctl call.

Allow the mounting of OBB filesystem images if they're encrypted with

  - Fix issue where container-names > 64 bytes were getting truncated in the
    kernel. lo_name is only 64 bytes in length, so we now hash the container
    id via md5
  - Add 'dump' command to dump loop and devicemapper status
  - Add 'debug' command to enable more detailed logging at runtime
  - Log vold IPC arguments (minus encryption keys)
  - Fix premature return from Loop::lookupActive() and friends

  In order to protect the '/android_secure' directory on VFAT removable media
from being mucked with by 3rd party applications on the device, we hide the
directory with a read-only, zero-sized tmpfs mounted on-top. A reference to the
hidden directory is kept by a bind-mount which is mounted at a location which
only root can access.

Staging consists of:
  1. Mount checked media at a secure location (/mnt/secure/staging)
  2. Ensure /android_secure exists on the media, (creating if it doesnt)
  3. Bind-mount /mnt/secure/staging/android_secure -> /mnt/secure/asec
     (where only root can access it)
  4. Mount an RDONLY zero-sized tmpfs over /mnt/secure/staging/android_secure
  5. Atomically move /mnt/secure/staging to the publicly accessable storage
     directory (/mnt/sdcard)
