It turns out the standard explicitly states that if the pointer is
null, the deleter function won't be called. So it doesn't matter that
fclose(3) doesn't accept null.

This patch removes costly O_SYNC flag for encrypted block device.
After writing whole decrypted blocks, fsync should guarantee their consistency
from further power failures.
This patch reduces the elapsed time significantly consumed by upgrading packages
on an encrypted partition, so that it could avoid another time-out failures too.

Move uncrypt from /init.rc to /system/etc/init/uncrypt.rc using the
LOCAL_INIT_RC mechanism

Clean up leaky file descriptors in uncrypt/uncrypt.cpp. Add unique_fd
for open() and unique_file for fopen() to close FDs on destruction.

When it reboots into recovery for a factory reset, it still needs to
write the uncrypt status (-1) to the pipe.

uncrypt needs to be triggered to prepare the OTA package before
rebooting into the recovery. Separate uncrypt into two modes. In
mode 1, it uncrypts the OTA package, but will not reboot the
device. In mode 2, it wipes the /misc partition and reboots.
Needs matching changes in frameworks/base, system/core and
external/sepolicy to work properly.

Fix the accidental change of behavior in [1]. OTA packages not on /data
partition should still go through the path that has validity checks and
wipe_misc() steps.

This should reduce errors if the device reboots before the blocks
are commited to disk.

Always create the block map for packages on /data; don't only look at
the encryptable/encrypted flags.

Opening the misc block device in read-write mode runs afoul of
SELinux, which keeps the wipe code from working. Fix. Also change
various things to log to logcat so we can see them happening, for
future debugging.

Something is leaving behind wipe commands in the BCB area of the /misc
partition. We don't know what is doing that. It should always be
safe to zero out that area from uncrypt, though (because if uncrypt is
running then it's got the command we want in the recovery command file
rather than the BCB).

When going into recovery mode withoug recovery command file present, uncrypt crashes
and the device gets stuck and eventually shuts down.
Check that the command file is present before trying to read from it.

uncrypt can read a file on an encrypted filesystem and rewrite it to
the same blocks on the underlying (unencrypted) block device. This
destroys the contents of the file as far as the encrypted filesystem
is concerned, but allows the data to be read without the encryption
key if you know which blocks of the raw device to access. uncrypt
produces a "block map" file which lists the blocks that contain the file.
For unencrypted filesystem, uncrypt will produce the block map without
touching the data.
