Enable libsnapshot to export the size of the COW image, representing the
fraction of the COW device that is temporarily created in the /data
partition, computed just before initializing a merge operation.
Thise additional information can be used by other components (i.e.,
update engine) to enrich Virtual A/B metrics.

If the first call for pullFinished fails, it is likely because the
transaction is too large. Currently, if this happens statsd will just
sleep until the timeout. With this change, the client will retry calling
pullFinish if the first attempt fails, but with an empty payload (and
with success = false) to cause the puller to fail fast, and so statsd
does not wait for the timeout.

When delivering single-stage, non-AB OTAs, the updater binary is built
on a newer OS than recovery is compiled with. libdm relies on newer ueventd
behavior which therefore breaks this model. As a workaround, we allow
libdm to fallback to the old ueventd logic if the following conditions
hold true: (1) we're in recovery, (2) the device is not an AB device,
and (3) the release is <= 10.
Since the old ueventd behavior can lead to races in libdm, this fallback
should stay as narrow as possible.

The FUSE filesystem is implemented by a Zygote child. If Zygote dies,
all of its children die along with it, including the FUSE daemon. The
FUSE filesystem is cleaned up automatically whenever the /dev/fuse file
descriptor of the FUSE daemon is closed. However, due to the way the
binder driver holds on to the 'struct files' of processes in the kernel,
the closing of FDs of all of Zygote's children is serialized.
That in turn means that, if a process has a file with dirty pages on
FUSE, and that FD is closed *before* the FUSE FD, the FUSE kernel driver
will happily issue a request to the FUSE daemon to serve that request.
But since the FUSE userspace daemon is already dead, it will never get
served. And because the closing of all FDs is serialized, we will never
close the FUSE fd to unblock this request.
Solve this particular case by manually aborting the FUSE filesystem when
Zygote restarts. Because we now explicitly close the FUSE fd, the FUSE
filesystem will be cleaned up, all outstanding requests to it will be
cancelled, and new ones will be skipped.

Test: kill zygote manually

Currently the ReadDefaultFstab function, which calls GetFstabPath,
makes some assumptions about what the fstab will be called and where
it is located. This is being used by vold to set up userdata encryption
and for gsid, and is even used in the default boot control HAL, so it
has become quite baked.
The original way for a board to specify things to mount was to use the
"mount_all /path/to/fstab" command in init.rc. However, due to the
above functionality, the path after mount_all is no longer very useful,
as it cannot differ from the inferred path, or userdata encryption and
other features will be broken.
On Cuttlefish, we have an interest in being able to test alternative
userdata configurations (ext4 vs f2fs, encryption on/off, etc.) and
currently the only way to achieve this is to either a) modify the
ro.hardware or ro.hardware.platform properties, which breaks a bunch
of things like default HAL filenames, or regenerate our odm.img or
vendor.img filesystems. We can't simply install another fstab and
point to it with "mount_all".
This change allows the fstab path to be omitted from "mount_all", and
adds another property which overrides the existing checks for
fstab.${ro.hardware} and fstab.${ro.hardware.platform}. Specifying
${ro.boot.fstab_suffix} will cause fstab.${ro.boot.fstab_suffix}
to be checked first.

After USB disconnection, io_submit will block until the endpoint comes
back up. We handle this in the worker thread by sending it a signal to
break it out of io_submit when we notice that USB has gone down, but
opportunistic writes from the main thread can get stuck in this scenario
as well. Submitting the writes only on the worker thread doesn't have a
measurable impact on performance, so avert this scenario by only
submitting writes from the worker thread.

Because DSUs mount userdata via a fiemap, libfiemap has trouble creating
additional fiemaps on top of it. The complex stacking of dm-linear is
not supported. For other libfiemap tests we've hacked around this
limitation. If LpMetadata is in a folder named "test", we allow the
backing device search to stop at a dm node, whereas otherwise it would
need to stop at a physical device.
However this was not quite enough for vts_libsnapshot_test, because (1)
the test folder was not included in the pattern match, and (2)
CreateLogicalPartition() could not handle device-mapper names, as it
expects a named physical partition. Addressing both of these allows the
tests to pass on DSUs.

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.
Copy the AVB footer to the end of the partition before flashing, if it
is not there already.

With GKI we find in certain situations the timing of the drivers
loading is delayed as compared to a monolithic kernel. This
introduces a race where during second stage init, the attributes
inside /sys/class/udc/ might not be set by the time
SetUsbController() is called.
To address this, we also call SetUsbController() until the property
sys.usb.controller is set at the bottom of the event loop.
