It is just a wrapper around GetDynamicPartitionControl()->Cleanup().
Delete it and let callers call it instead.

Replace with GetDynamicPartitionControl()->PreparePartitionsForUpdate(
GetCurrentSlot(), ...).

Add BootControlInterface::GetDynamicPartitionControl, which
exposes the internal DynamicPartitionControlInterface object.
BootControlStub / FakeBootControl / BootControlChromeOS uses
DynamicPartitionControlStub (all functions succeeds).
BootControlAndroid uses DynamicPartitionControlAndroid.
GetPartitionDevice is exposed so that BootControlAndroid can use it.
Follow-up CLs delete duplicated PreparePartitionsForUpdate
and Cleanup from BootControlInterface so that BootControlAndroid remains
a thin wrapper of the HAL (+GetPartitionDevice, which exists before
dynamic partitions.)

DynamicPartitionControl need the list of operations to calculate
COW sizes.
- Remove BootControlInterface::PartitionMetadata. Replace all references
with DeltaArchiveManifest. DeltaArchiveManifest has all information
that PartitionMetadata has.
- Rename all InitPartitionMetadata to PreparePartitionsForUpdate
- Change all PreparePartitionsForUpdate to use new signature

BootControlAndroid::InitPartitionMetadata() should always be called when
starting / resuming an update that uses dynamic partitions. This allows
updating the metadata for the target slot, as well as setting up the
internal state for accessing the dynamic partitions in the target slot.
Bug: 122097567
Test: Run update_engine_unittests on taimen and blueline.
Test: Apply a payload that uses dynamic partitions. Reboot before it
finishes, then resume the update.

Adds updateable group support to OTA.
* DeltaPerformer combines partition sizes with
dynamic_partition_metadata to
BootControlInterface::PartitionMetadata.
* BootControlAndroid::InitPartitionMetadata:
* Copy all groups / partitions from source metadata slot
* Remove all groups / partitions mentioned in the manifest (of the
target slot)
* Re-add all groups / partitions mentioned in the manifest.
* BootControlAndroid::InitPartitionMetadata can check
the incoming PartitionMetadata to see if a partition is dynamic
or not. The guessing logic is completely removed.
* Because a partition is removed then re-added, there is no need
for preserving the entry with size 0 to indicate that a partition
is removed. When update_engine sees a partition in a group "foo" on
the device, but manifest contains group "foo" without the partition,
it removes the partition.
* Hence, Removing a partition does NOT require keeping the entry (i.e.
RemovePartition is used instead of ShrinkPartition(0) ). This makes
retrofitting dynamic partitions on older devices easier.
The following is now allowed:
- Adding / removing / resizing partitions
- Adding / resizing groups
It is not allowed to remove a group, but a group can always be resized
to zero to deprecate it.

In a following CL, InitPartiitonMetadata not only
takes sizes but also group of each partition. Rename
the struct to a more generic name.

update_engine uses device mapper to resize dynamic partitions
before opening the devices to apply the update.
* DeltaPerformer calls BootControlInterface::InitPartitionMetadata
when parsing the update manifest. The implementation for
BootControlAndroid::InitPartitionMetadata does the following
if sizes for dynamic partitions are incorrect (assuming updating
from slot A to B):
* Load metadata from metadata slot A
* Delete all extents of partitions at slot B (with _b suffix)
* Add extents for partitions at slot B
* Write metadata to metadata slot B
* Re-map all partitions at slot B using metadata slot B with
force_writable = true
* BootControlAndroid::GetPartitionDevice() checks device-mapper
before returning static partitions.
* PostinstallRunnerAction::Cleanup calls BootControlInterface::Cleanup
which unmaps all partitions at slot B.
A partition "foo" is considered dynamic if foo_a exists as a dynamic
partition OR foo_b does NOT exist as a static partition.

This patch splits from the main libupdate_engine code the part that
is strictly used to download and apply a payload into a new static
library, moving the code to subdirectories. The new library is divided
in two subdirectories: common/ and payload_consumer/, and should not
depend on other update_engine files outside those two subdirectories.
The main difference between those two is that the common/ tools are more
generic and not tied to the payload consumer process, but otherwise they
are both compiled together.
There are still dependencies from the new libpayload_consumer library
into the main directory files and DBus generated files. Those will be
addressed in follow up CLs.
Bug: 25197634
Test: FEATURES=test emerge-link update_engine; `mm` on Brillo.
