It's extremely difficult to test storage related logic on devices
that don't have physical SD card slots. So to support better
debugging and testing, add a new "virtual disk" feature which mounts
a 512MB file through loop device.
It relies on the kernel having the "loop.max_part" value set to
something other than 0 via the boot command line, since that allows
all the existing partition logic to fall into place.
Bug: 34903607
Test: builds, boots, virtual disk works

Changing the num_sectors used in ioctl with BLKGETSIZE because
the kernel expects an unsigned long type and then changes 64 bits
with a 64 bits userspace. This overwrites what's located close to
the parameter location if any.

ioctl(BLKGETSIZE) expects unsigned long
(8 bytes on 64 bit environment).
This is fixing fails in android.os.storage.StorageManagerIntegrationTest
(in FrameworkCoreTests).
To verify, install FrameworksCoreTests.apk and do:
adb shell am instrument -r -w -e class android.os.storage.\

ASECs formatted as ext4 can now be resized using vdc asec resize.
Refactored some common code.
Requires resize2fs.

Now forward locked applications will be in ASEC containers both internal
to the system and externally.
This change adds support for putting applications in ext4-based ASECs.

- Fix issue where container-names > 64 bytes were getting truncated in the
kernel. lo_name is only 64 bytes in length, so we now hash the container
id via md5
- Add 'dump' command to dump loop and devicemapper status
- Add 'debug' command to enable more detailed logging at runtime
- Log vold IPC arguments (minus encryption keys)
- Fix premature return from Loop::lookupActive() and friends

- Supports up to 4096 containers
- Keys are now implemented - specifying a key of 'none' means no encryption.
Otherwise, the key must be a string of 32 characters
