Maintain and query some internal state to know if it's OK to run
the various cryptfs commands. Do not allow enablecrypto to run if
the device is already encrypted. Do no allow restart to run if
we have already run it before or if the password has not been
validated. Do not allow checkpw to run if not encrypted, or it
has already validated the password.
This is an extra layer of safety on top of the checks up in the
UI code agains possible DoS attacks on the device.

Also, change the value that triggers the progress bar framework from
"startup" to "0" in the property vold.encrypt_progress.

Update the enable inplace API to allow the UI to show a progress bar.
Add new command changepw (whichis currently not working)
Internal restructuring of code to support these two features.
Some minor cleanup of the code as well.
Change-Id: I11461fc9ce66965bea6cd0b6bb2ff48bcf607b97
In order to make the animations and the UI look right, we need to change
the cryptfs checkpw command to return a status if the password was
correct or not, and not have it automatically restart if it's correct.
There is a new command restart that will restart the framework with the
encrypted filesystem.

Now that the framework shuts down quickly, remove the 30
second sleep when enabling crypto. Also, stop spewing
the secret master key to the disk in the system log!

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.

vold: fix an offset one bug that makes partition 4 unusable
vold: set state back to idle on formatting error
On formatting error due to some reasons, the state is left at
Formatting, therefore the user is unable to mount the sdcard
again. The patch sets the state to Idle no matter formatting
error or not.

ENOENT is more descriptive than the generic error that EINVAL gets
turned into. Then we can actually treat it how we want on the other
side.

Track type of container mounted
OBB and ASEC are tracked in the same active container list, but when it
comes time to unmount everything, it was trying to unmount the OBBs
according to ASEC rules. This led to the OBB not being unmounted and the
volume unmount failing.

Avoid array overrun. We can now mount the /sdcard partition on our boot sdcards
LOOP_GET_STATUS64 isn't useful here since the data contained within
isn't actually checked, so stick with the regular LOOP_GET_STATUS here
to match the struct loop_info we're using.

ioctl call.
