The previous problem of the framework not properly restarting after accepting
the password to decrypt the storage is also a problem when restarting the
framework to display the encryption progress screen. So like the previous
hacky fix, add a sleep to wait a few moments before proceeding. Also,
increase the sleep of the previous fix from 1 second to 2, as the problem
was seen once more in testing. A proper fix has been designed and hopefully
will work and be checked-in RSN.

There is a race in the encryption code that after it accepts the
decryption password, it tells init to kill all the processes in
class "main", then it mounts the decrypted filesystem, preps it,
and restarts the framework. For an unknown reason on some devices,
the new framework sometimes starts up before init has killed and
reaped all the old processes. The proper fix is to make the killing
of the old framework synchronous, so vold waits till all the
processes have died. But with factory rom a few days away, the
much more pragmatic solution of adding a sleep of 1 second after
telling init to kill the old framework will suffice.

To support multi-user emulated storage, we mount rootfs as MS_SHARED,
which means we can't MS_MOVE existing mount points rooted in the
shared subtree. Initial staging is still able to MS_MOVE, since it's
rooted in a MS_PRIVATE tmpfs rooted at /mnt/secure.
This change fixes unmounting by operating in-place instead of trying
(and failing) to MS_MOVE back to staging.

The kernel seems to return from umount(2) sometimes before it has
released the underlying block device. So until the kernel is fixed,
try up to 10 times to load the crypto mapping table, waiting 500 ms
between tries.

Mount OBB containers using shared app GID, so that an app can read
the mount point across users.

Augment the Ext4::format function to take
a mountpoint parameter. This will then
be passed to make_ext4fs through the
-a option to allow proper security labeling.
