The "OwnsSector" tests did not work if one range fit completely inside
another range. The new OverlapsWith() methods address this case.

loop_control.h already provides loop device management APIs that we need
here. In addition, this change fixes a subtle race condition between
uevented creating a loop device node in userspace and
PrepareZramBackingDevice accessing it without waiting for it to be
created.

In vts_libsnapshot_test, liblp was explicitly imported as static
library, but due to the importing of libsnapshot_defaults, it also
inherited the shared importing.
The import in libsnapshot_default, is not required, drop it.

libsnapshot* uses update_metadata-protos. This

This is preferred over SnapshotMergeStats::GetInstance because
the latter needs a concrete SnapshotManager, not the ISnapshotManager
interface.
SnapshotManagerStub::GetSnapshotMergeStatsInstance returns
a SnapshotMergeStatsStub instance.

This test is pretty straight forward: create two large files, then merge
one into the other while injecting kernel crashes. At the end,
block-by-block validation is performed against both the snapshot-merge target
and the file written to disk.

Use realpath as a canonical representation of block devices. This makes

fs_mgr_get_mounted_entry_for_userdata didn't properly work on devices

To make it easier to support disk formats created using old versions
of dm-default-key with new kernels, stop checking the kernel module
version; instead, the caller decides whether to use the old or new
options format.

If the value of androidboot.boot_devices has a comma in its path, it'll
get split and /dev/block/by-name symlinks won't work. As a workaround,
add "androidboot.boot_device" as a valid command-line parameter. It can
be repeated multiple times to retain multiple-boot-device semantics.

In case of GSI on DSU, /data is mounted on the following stack:
userdata -> userdata_gsi -> actual block device, and fstab returned from
ReadDefaultFstab() function will say that /data should be
mounted onto userdata_gsi. This configuration wasn't supported.
To support it, fs_mgr_get_mounted_entry_for_userdata now unwinds the
dm-device stack /data is mounted onto, and for each entry in fstab
resolves corresponding block device (in case of logical partitions by
asking DeviceMapper to resolve name -> path, and for other cases by
reading a symlink), and then checking whenever resolved block device
belongs to the unwinded stack.
