fcf24fe62f vold: Add a versioned superblock to secure containers. 
Add an un-encrypted superblock to the end of a secure container to
help identify the crypto cipher used. This is required in order to
provide some semblence of versioning, in case we have cause to
change the crypto type on an update - say for example switching
from software to hardware encryption, or from 128 -> a zillion
bit keys.

NOTE: This format is incompatible with previous secure containers.
After this change they will no longer be mountable.

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)

b3b4318ab8 Check length of filenames before strcat 
Just in case someone tries to set up a series of links to trick us, do a
quick sanity check on the total length of the strings we're about to
concatenate.
