commit 29eea977b114eeebf54808cc1fcaa5107bd15f7b
Author: Kevin Marshall <kmarshall@chromium.org>
Date: Wed Jan 10 00:08:08 2018

Initial implementation of new SSH-based Fuchsia runner libraries.

The new runner is based heavily around the use of SSH and SCP.
Rather than build large boot filesystems with Chrome or test binaries,
as we do now, we will instantiate a basic Fuchsia instance and use
SSH for our binary deployment, execution, and log extraction needs.
It can also be used as a layer to facilitate connections between the
client and server portions of the Blink layout test system.

This CL defines the abstraction layer for connecting and interacting
with a Fuchsia target, and implementation code for using it on QEMU.

commit c4ec08a5c87d988d32990d346e3ed2b3c497d551
Author: Kevin Marshall <kmarshall@chromium.org>

Fuchsia: Create new runner scripts which leverage packaging and SSH.

Generates an alternative runner script for each test target,
with a "_v2" suffix, e.g. run_base_unittests_v2.
The old-style generated runner scripts will still be without the
"_v2" suffix, but they will be deprecated and removed soon as part
of a followup CL.

The new scripts will bring up a new QEMU VM, a Zedboot physical
device, or continue to use an existing device that is currently
accepting SSH connections.

Once connected, the scripts push the package bits onto the device,
execute the package using SSH, extract the build logs and other
artifacts from the device, and finally clean up the state.

Other changes:
* Add DeviceTarget impl for deployment.
* Use relative paths in package archive manifests, for symbolization.
* Add logging statements everywhere, and a -v switch to turn them on.
* Add package cleanup teardown step, to avoid cluttering up long-running
  devices.
* Refactor symbolization as a stream filter object.

Fuchsia: enable SCP compression.

Enabling compression trims 40-60% from the package sizes. Performance
is substantially improved for slow network links, e.g. virtualized I/O
on swarming clients.
