Fix for bug 3415286. Trigger an action in init.rc to load the persistent
properties after /data has been decrypted and mounted.

The new android_reboot() function is a nicer way to reboot.
It can optionally sync(2) and remount as read-only writable
filesystems. This fixes bug 3350709.

Need to detect if the encryption process didn't finish successfully, and if
so, provide a way for the UI to detect that and give the user an option to
wipe the system clean. Otherwise, the user is stuck in a reboot loop, and
they will need to do magic button presses to enter recovery and wipe the
device to get out of it.

To determine whether a loop device was available, we use an ioctl call
to LOOP_GET_STATUS, but this fails on devices with large storage
partitions with errno = EOVERFLOW. Instead use LOOP_GET_STATUS64 which
succeeds.

Bug 3384231 is punted to MR1, but the code to set the flag is already
in the tree, so this CL does 3 things:
1. Comments out the lines that set the flag
2. Removes the change to the checkpw that was added in the last change.
3. Implements a new command to check the flag (which no one is calling
yet and the flag won't be set anyhow).
When MR1 comes, it will be a simple matter to enable the flag setting
code and start testing it.
The fear is a false positive detection of incomplete encryption could
cause people to be prompted to wipe their data when MR1 comes out and
the flag is checked. Not setting this for first release, and testing
this more before MR1, will give us confidence that the code will not
detect false positives of encryption failure.

For the case there encryption failes to complete because of a kernel
crash or the user power cycling the device, define a flag in the
crypto footer that says encryption is in progress. Set it when starting
the actual encryption, and clear it when it successfully completes.
When the user is asked for the disk password, if the flag is set,
return a special error to the caller so the UI can know to tell the
user there is no valid data on the disk, and present a button to
wipe and reset the device.

The Progress bar UI grabs a full wakelock when encrypting, but we've seen
a case where it looks like the progress bar UI crashes, and the wakelock is
lost, and then all hell breaks loose. The enablecrypto command has a lot of
work to do, and it will take some time, so it should grab a wakelock to
ensure it can finish without being interrupted and put to sleep.
It grabs a partial wake lock, as it doesn't need the screen to be on to do
its work. If the UI wants to keep it on, it should also grab a full wakelock,
which it does. If the UI crashes, the screen may turn off, but the encryption
will keep going, and vold will reboot the device when it's done.
