This is a re-landing of the original CL, with a few changes:
- The correct device is now returned in MapUpdateSnapshot.
- The old API is used for tests, and the new API is only tested when
used on a VABC device.
- A sync() call has been added to ensure that writes to the base and
target snapshot devices have been fully flushed. This makes
IsPartitionUnchanged detect the MapUpdateSnapshot bug.
Implement OpenSnapshotWriter for non-compressed Virtual A/B. This is
done by adding an OnlineKernelSnapshotWriter class, which forwards all
writes to a dm-snapshot block device.
This also introduces a new ISnapshotWriter class which extends
ICowWriter, and adds features specific to libsnapshot (versus ICowWriter
which is intended only for the new COW format). The OpenSnapshotReader
call has been moved here since the writer retains all the information
needed to create the reader.
To test the new call, vts_libsnapshot_test has been modified to use
OpenSnapshotWriter.
As part of this change, all consumers of libsnapshot must now link to
libsnapshot_cow.

If oem doesn't implement this specific API in fastboot_hal lib,

The build system has added the new target named 'linux_cross' which is
the cross-compiled (i.e. arm on x86) host target. libfastboot is now
configured to use usb_linux.cpp not only for linux_glibc (which is the
native host target using glibc), but for all Linux-based host targets
including linux_glibc, linux_bionic, and the new linux_cross.
Note that the device target 'android' is also included in the 'linux'
target. But that doesn't cause a problem because libfastboot is a host
library which is not enabled for the device target.

If the flashed boot image is smaller than the block device, the AVB
footer will not be at the end of the partition. Although images are
normally created to match the partition size the GKI boot.img must work
on all devices, and the size of the boot partition will vary.

is not there already.

Status() is called with an empty string to handle `fastboot oem`
commands. This currently emits a set of spaces and sets
last_start_time such that the epilog can track the time spent in this
command. Emitting the spaces is problematic however, since it results
in the follow:
$ fastboot oem device-info
(bootloader) Verity mode: false
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: true
(bootloader) Charger screen enabled: true
OKAY [ 0.000s]
Finished. Total time: 0.000s
If we skip emitting the spaces, then we get the correct result:
$ fastboot oem device-info
(bootloader) Verity mode: false
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: true
(bootloader) Charger screen enabled: true
OKAY [ 0.001s]
Finished. Total time: 0.001s
There are no other uses of Status() with an empty string, so this
changes won't impact other commands.

It's not possible to programmatically determine which fastboot mode a
device is in, without sending a getvar:is-userspace query. Unfortunately
this is not possible asynchronously, and may interrupt other queries
being processed.
This patch changes fastbootd's USB interface name to "fastbootd". Note
that tools use the protocol number/class and not this string, so it
should be safe to extend. When using "fastboot devices", the interface
name is now listed if set. Note that currently only the Linux version of
the fastboot tool is capable of reading the interface name.

When merging in recovery, the "imminent data wipe" code was used, which
made the assumption the /metadata and /data state would be zapped. This
caused future OTAs to error because the old snapshots were detected.
This CL allows OTAs to proceed even if unexpected snapshots are present.
It also forces the state to "MergeCompleted" after a merge in recovery,
so that the next normal boot can perform cleanup.
