Linux doesn't seem to actually support emitting them, so we can't check
that they're actually there, but commit the code to read them so that
if and when Linux gets support, it's easier to check.
This also adds some error checking for ill-formed binary object store
entries.

When we run MapPartitionWithSnapshot, intermediate devices aren't
cleaned up if the call fails. Hence, record these intermediate devices
we have created along the way using the new AutoDevices class. Upon
failure, the AutoDevices object will be destroyed, and all the
intermediate devices will be deleted from device mapper or image
manager. Upon success, AutoDevices::Release() makes sure the
intermediate devices aren't deleted.

Create / Deleting the COW image / snapshot changes states, so it makes
sense to require an exclusive lock before doing so. If caller doesn't hold
an exclusive lock, parallel calls to MapCowImage / MapSnapshot / UnmapCowImage /
UnmapSnapshot may have weird results.

Move operations on image manager in *Snapshot functions to their own
functions for finer granularity in control. *Snapshot functions only
changes snapshot state and snapshot devices, but not the supporting
devices.
Now, MapSnapshot can take a customized COW device path. We will have
a more complicated stack for the COW device in upcomming CLs.
Also, Change SnapshotManager::CreateSnapshot's signature to
accept a SnapshotStatus struct that includes all sizes, so that
cow_partition_size and cow_file_size can also be written to the snapshot
status file.

On every boot, there is a "duplicate" message logged at INFO level for
every system device-encrypted directory, e.g.:
1 1 I init : Setting policy on /data/app-private
1 1 I init : Encryption policy of /data/app-private set to 3a19970b1aa3abed modes 127/4
Or:
1 1 I init : Setting policy on /data/app-private
1 1 I init : Verified that /data/app-private has the encryption policy 3a19970b1aa3abed modes 127/4
(Before I51ee70706bc9ccb216ccefd7bdfbbfc57faae14d the second messages
were slightly different, but were similar and still at INFO level.)
The issue is that set_system_de_policy_on() prints its own log message,
then calls fscrypt_policy_ensure() which prints a message too; and the
second message is essentially a superset of the first.
Clean this up by removing the message from set_system_de_policy_on().
Test: Booted and checked the log.

Add exec_reboot_on_failure builtin and refactor the VDC commands that
had similar functionality. These will now also reboot in the case
that the program cannot be found or run for any reason.
Test: boots normally, reboots if command is not found or if command
returns status '1'

Previously this test would rely on ro.debuggable being true, but there
are now some circumstances where ro.debuggable is true, yet `su` does
not exist. Therefore we only run this test when it is root.
Also simplify some of the test macros.

Test: passes as root, skips as non-root

We're now adding a core CSI system.img that is common across different
targets. So GSI-specific files should be moved to system_ext partition.
Note that GSI is a system.img that includes the contents of product and
system_ext partitions, under /system/product and /system/system_ext,
respectively. That's why it's under /system/system_ext instead of
/system or /system_ext.

- Open up GetFreeRegions() API.
- Add a new argument, free_region_hint, to ResizePartitions(). It
indicates the regions that extents can be allocated to.
- Expose Interval::Intersect functions. libsnapshot needs the algorithm
to intersect extents to find out the free regions for COW partitions.
