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
twofish and in FAT filesystem format.

- 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)

- share command was taking wrong arguments
- shared command was returning two termination codes
- Force FAT32 cluster size to 4k when formatting
