This class helps export a list of regions comprising a super partition,
and what the contents of those regions should be. It is very similar to
ImageBuilder, except that it does not require actual partition image
files, nor does it actually write an image file to disk.
The goal is to support building an in-memory super image that uses as
little memory and backing storage as possible. For example, fastboot can
use this to upload a super image without having to read and write
gigabytes of unnecessary data.
Since the goal is to optimize fastboot, we've taken some shortcuts here.
Retrofit devices and other edge-casey behavior are safely rejected. We
also don't rely on libsparse behavior here, and attempt to make the
translation to sparse records as trivial as possible, by explicitly
declaring where fill/dontcare gaps are, and only exporting 4KB aligned
regions. Hopefully this will allow the code to be portable to
non-fastboot consumers.

- Fix test so that it skips compliance test on non-DAP devices
and retrofit devices as well. Move these device-dependent tests
into the DeviceTest test suite and skip them on non-DAP devices.
- Also add "ResetPropertyFetcher" in some tests in io_test.cpp.
- Also change some ASSERT to EXPECT.
Note that VtsKernelLiblpTest runs this test. VtsKernelDynamicPartitionsTest
enforces ro.boot.dynamic_partitions to be set.

This change introduces an IPartitionOpener abstraction. Methods that
interact with live metadata, such as ReadMetadata, UpdatePartitionTable,
and FlashPartitionTable, now require an IPartitionOpener object. Its
purpose is dependency injection: it will make these methods much easier
to test when the super partition spans multiple block devices.
All non-test consumers should be using PartitionOpener, and as such,
some helper methods have been added that automatically create one.

Block devices in the Linux kernel have a "minimum I/O request" size. The
minimum size is usually acquired by the block driver and can change
from device to device. When stacking devices (such as with
device-mapper), the kernel goes through great lengths to make sure this
alignment is respected for optimal I/O. In device-mapper's case,
misalignment can lead to kernel warnings and performance issues.
While this is unlikely to matter with a few targets, it could become
problematic on a large number of targets, and so we would prefer to
align all partition extents to the minimum I/O size.
We now support two new properties in the partition table geometry: an
"alignment", which is the minimum I/O size, and an "alignment offset",
which is an offset that when applied to sector 0, causes the sector to
be properly aligned within its parent device (for example, if a
physical partition is misaligned). All partition extents now begin on a
sector that respects this alignment.
One major caveat is that it is difficult for the initial partition table
to have the correct alignment without build system and/or flash tool
support. To accomodate this, all alignment is optional, and the lpmake
tool will support a default alignment of 1MiB as a failsafe.
