ro.virtual_ab.userspace.snapshots.enabled is a vendor property which isn't present in Android S. Hence, during OTA install with S vendor, userspace_snapshots is disabled.
However, both update_engine and snapuserd are already on the system partition during install. Hence, forcefully enable userspace_snapshots if this is a path of legacy dm-snapshots with Vendor on Android S.

Wait for the device to disconnect when rebooting to userspace fastboot.
This is a particular problem for USB-over-IP devices, which must tunnel
the USB commands over a relatively-slow network and thus will not
disconnect as quickly as local ones.
Only currently effective for Linux hosts, since LinuxUsbTransport is the
only transport that implements WaitForDisconnect().
Test Plan:
provision with a usbip-attached device, see flash succeed

Change the meaning of batch_size_. Previously, a batch size of 200 meant
200 compressed data ops. With variable block size, each compressed data
op can be up to 256k uncompressed size -> batch size meaning should be
changed to 200 blocks of block size.
With this being said, the default batch size can be increased to 4mb to
better accomodate variable block size
The way we calculate the number of blocks to compress at once also
needs to be changed. Since there's no way of determining the comperssed
data size ahead of time, allow overwriting the cache by batch_size_ and
then flushing the cache as needed

Because the log message "Tombstone written to: $NAME" is written
before renaming the proto tombstone, it is possible that a tool that
automatically downloads new proto tombstones by watching for this
log message will fail to download the tombstone. For the tool that
I am developing, this occurs < 0.1% of the time. Fix the issue by
renaming the proto tombstone first.

Currently if our iov that we are trying to write is greater than 1024
our write will fail with error "INVALID ARGUMENT". This is because
pwritev() system call takes a max input size of IOV_MAX (which is device
dependant).
With our increased cache size of 1mb or maybe even more (or if user
configures batch size to be large), our write size could be greater than
IOV_MAX, and will fail with an unhelpful error. We should chunk these
writes to ensure they succeed.

During OTA install, when vendor partition is on Android S, add a new flag in SnapshotUpdateStatus file to indicate that we need to support dm-snapshot based snapshot process. This will be used only during post OTA reboot.
The primary change here is the OTA install path. Earlier, dm-snapshot based approach was used; with this change, since both "snapuserd" and "update-engine" resides on system partition, OTA installation will use the userspace snapshot approach.
To maintain backward compatibility, the new flag "legacy_snapuserd" is used only after OTA reboot. This flag will make sure that update-engine will take the dm-snapshot based approach post reboot and for the entire duration of snapshot-merge.
Additionally, during first-stage init if the vendor is on Android S, then "snapuserd" binary will continue to work based off dm-snapshot as none of this change will impact the mount process.
