Increase max image depth to 127
added authConfig to docker build
Engine: new command 'kill' sends a signal to a running container
Hack: use new 'kill' command in integration tests
gofmt
Engine: port 'kill' to the new integer status.
Engine: don't log job stdout to engine stdout (it might be non-text output, for example tar data for 'export'
Engine: 'export' returns a raw archive of a container's filesystem
Simplify and resync hack/make/test and hack/make/dyntest output handling
Clean output and simplify hack/make/*test by adding go_test_dir function in make.sh
Add much better pruning of non-tested directories, including pruning the integration tests directory (doing more with "find" and nothing with "grep")
Unify hack/make/*test further by invoking hack/make/test directly from dyntest
Unify dyntest/test and dynbinary/binary hack bundlescripts further by cross-invocation and keeping all the logic in one place, taking advantage of LDFLAGS_STATIC that is the only bit that gets replaced for dyntest/dynbinary
Add separate "test-integration" bundlescript (and corresponding dyntest-integration bundlescript)
Prevent deletion of image if ANY container is depending on it; not just running containers
refactor and fix tests
fix docker images -tree <invalid_image> and docker images -viz <image_name>
fix size in -tree
Update mkimage-debootstrap with even more tweaks for keeping images tiny by more aggressively removing cache files and by not downloading apt-cache Translations files
update docker push to use [====>    ]
