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.

Clean up ASEC unmounting on physical storage.

When physical devices are unsafely removed, unmountAllAsecsInDir()
fails to find any ASECs, and leaves them all mounted, preventing the
rest of volume from going down.

Now we examine all ASEC containers, and remove when on external
storage, or when the storage media is no longer found.

Use correct minor device number to format SD card

When formatting SD card partitions, instead of assuming partition
minor device numbers start from 1, use (minor device number of
the disk device + 1) as the starting point.

vold: cryptfs: Don't update KDF without validating pwd/key.

Prior to this, the Key derivation function would get
 blindly updated even if the user entered the wrong password.
Now, we only attempt to upgrade the KDF if the pwd/key have
been verified (i.e. after a successful mount).

vold: Raise MAX_PARTITIONS to 32

 * We raised this in 10.2 globally, lets put it back to 32 so that
   new bringups don't get stuck on this. It's likely that every single
   device which uses physical, nonremovable volumes with vold will hit
   this limit.

* These variables may actually be checked before they are set. Set them

vold: don't crash when formatting unformatted volume

When formatting unformatting volumes, fstype will be NULL causing
a crash in strcmp. Set it to "vfat" to avoid the crash.

vold: Allow specifying the filesystem type when formatting

 * Optional parameter added to "volume format" to specify the filesystem
   type to use. If not specified, default is to auto-detect.
 * Add support for formatting NTFS.
 * Use mke2fs to format when not creating containers.
