This code path was never invoked. is_logical will return false on
secondary partitions in retrofit devices, so nothing actually is ever
deleted. If we manage to call the delete, the device side code will
fail with "cannot open the super partition"

FastbootDevice::boot1_1 attempts to dereference a null pointer when the
boot_control_hal_ is not set. It needs a guard statement to prevent
that.
Test: Manually tested on device without BootControl.

Introduce new battery-soc variable to read battery
SSOC, this benefits manufacturing to better track
the SSOC after FSI image flashing in the userspace
fastbootd using the same approach as Android space,
otherwise it is difficult to implement the entire
battery SW stack from Android to fastboot bootloader
and generate the same test experience monotonically.

This fixes the case when all the following conditions are true:
1: Incremental OTA
2: When there are sequence of overlapping COPY operations within one merge-window
(510 blocks)
3: Device is rebooted when snapshot-merge is in-progress of this
merge-window. When device reboots, the state of merge-window (of 510 blocks) was
merge-in-progress (aka - only partial set of blocks were merged in
this window thereby the state of the base device is in-complete for
this window)
4: During the next boot, if there any I/O request from the filesystem
which maps to the merge-window in (3):
a: The data has to be retrieved from the scratch space of the
COW until the snapshot-merge for that window is completed.
b: Once the snapshot-merge is complete for that window, data
has to be retrieved from base device.
The bug was in step 4(a) wherein I/O request was getting routed to base
device.
This patch addresses the above flow by fixing step 4(a).
A new vts test has been added to explicitly track this issue.
Additionally, there is no need to re-scan the partition if partition is in merge resume path. This should cut down the overhead of the scan.

Refactor writer, reader + parser to work off v2 version of
CowOperations.
Test: m libsnapshot. ota on cuttlefish

Reader + Parser v3 should be able to read V2 cow format written to disk.
This test reads in a small cow file written by basic_v2_cow_writer and
parses it to ensure this compatibility checks out.

This is similar to inspect_cow --extract-to, except it uses snapuserd.
It is a diagnostic host tool and uses the tooling added for host
testing.
Usage: snapuserd_extractor -cow COW_FILE -base BASE_FILE -out OUT_FILE
-num_sectors NUM_SECTORS
Unlike inspect_cow, this supports xor/copy operations.
The extractor code is separated into a utility file so we can use it for
additional tests later on.
Bug: N/A
Test: manual test

This adds an --extract-to argument to inspect_cow to verify that full

ops.

If someone is trying to use the sphal namespace, but it
isn't available, we should probably fix this code or add an
sphal namespace there or similar. Add log for more clarity.

The current code keeps a pointer to a local variable which doesn't
work too well. Change this to a unique_ptr and allocate the source
object that will be used instead.
Test: All unit tests pass.
Test: fastboot -w flashall on a mokey which crashed without this change.

We've updated the glibc header (and musl will just use the bionic uapi
headers), so this is obsolete (and getting in the way of someone trying
to use the PERFMON capability).
