Move the uncrypt domain into SELinux enforcing mode. This will
start enforcing SELinux rules; security policy violations will
return EPERM.

Per https://android-review.googlesource.com/82814 , uncrypt
needs to be able to read shell_data_files on userdebug / eng
builds. Allow it.

Add initial support for uncrypt, started via the
pre-recovery service in init.rc. On an encrypted device,
uncrypt reads an OTA zip file on /data, opens the underlying
block device, and writes the unencrypted blocks on top of the
encrypted blocks. This allows recovery, which can't normally
read encrypted partitions, to reconstruct the OTA image and apply
the update as normal.
Add an exception to the neverallow rule for sys_rawio. This is
needed to support writing to the raw block device.
Add an exception to the neverallow rule for unlabeled block devices.
The underlying block device for /data varies between devices
within the same family (for example, "flo" vs "deb"), and the existing
per-device file_context labeling isn't sufficient to cover these
differences. Until I can resolve this problem, allow access to any
block devices.
