0de365fc0a Extract UUID and label from inserted volumes.
Uses "blkid" tool to extract metadata from an inserted volume, and
reports it up to the framework.  This needs to happen in vold, since
only the FUSE-wrapped volume is visible to userspace.

Remove autorun sanitization, since FUSE takes care of this now.

Add support for that.

9caab76c6b vold: Add an optional wipe paramter to the volume format command
The new wipe option to the vold format command will invoke BLKDISCARD
on the partition before invoking newfs_msdos.  This will be used whenever
a full wipe of the device is wanted, as this is more secure than just
doing newfs_msdos.

344ca10856 Add in ext4 support for ASEC containers
Now forward locked applications will be in ASEC containers both internal
to the system and externally.

This change adds support for putting applications in ext4-based ASECs.

0b8b597193 Add the ability to revert a crypto mapping when unmounting a volume
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.

29d8da8cef vold: allow to store key in a file on another partition
Add support for keeping the keys in a separate file on another partition,
for devices with no space reserved for a footer after the userdata filesystem.

Add support for encrypting the volumes managed by vold, if they meet certain
criteria, namely being marked as nonremovable and encryptable in vold.fstab.
A bit of trickiness is required to keep vold happy.

a4886f1f8e More fixes for internal FAT partitions:
Fix formatting partitions beyond the first partition.

2dfe297ec4 Fixes for devices with internal FAT file system:
Only share a single partition via UMS if a specific partition
is specified in vold.fstab (rather than "auto")

Do not fail to reformat if MBR cannot be found.

d9a4e35861 vold: Bugfixes & cleanups
- 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

3bb6020e46 vold: Stage the mounting of media to hide the ASEC imagefile directory
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)
