Our `realpath` and `readlink -f` functions (required only because of MacOS,
thanks Steve) were poor substitutes at best. Mostly they were downright
broken. This thoroughly overhauls them and adds a test (in comments, since we
don't seem to have shell tests). For all the interesting cases I could think
of, the fakes act just like the real thing.
Then use those and canonicalize KUBE_ROOT. In order to make recursive calls of
our shell tool not additively grow `pwd` we have to essentially make the
sourcing of init.sh idempotent.
I ran build/run.sh w/o any args (by mistake) and it just said
`Invalid input.`
after several other steps. I had no idea whether I was doing something
wrong or if my env was busted. Clearly, I just forget to include the
command that run.sh was to invoke in the Docker container. But it took
me time to go track down where this error came from and why. So to help
others I just tweaked the error message to be:
`Invalid input - please specify a command to run.`
Very minor thing,I know, but if it helps others...

Use v1.6.2-1 tag for build.
Is there any reason these don't use the VERSION file like everything else? cc @luxas @ixdy
- give the docker-machine VM more memory and access to all CPU cores
- make DOCKER_MACHINE_NAME not readonly beacuse it is set by docker-machine
- redirect stderr to ignore unhelpful error messages
- unquote 'docker-machine create' argument

don't ship kube-registry-proxy and pause images in tars.
pause is built into containervm. if it's not on the machine we should just pull
it. nobody that I'm aware of uses kube-registry-proxy and it makes build/deployment
more complicated and slower.

Up to golang 1.6
A second attempt to upgrade go version above `go1.4`
Merge ASAP after you've cut the `release-1.2` branch and feel ready.
`go1.6` should perform slightly better than `go1.5`, so this time it might work

Cross-build hyperkube and debian-iptables for ARM. Also add a flannel image
We have to be able to build complex docker images too on `amd64` hosts.
Right now we can't build Dockerfiles with `RUN` commands when building for other architectures e.g. ARM.
Resin has a tutorial about this here: https://resin.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/
But it's a bit clumsy syntax.
The other alternative would be running this command in a Makefile:
```
# This registers in the kernel that ARM binaries should be run by /usr/bin/qemu-{ARCH}-static
docker run --rm --privileged multiarch/qemu-user-static:register --reset
```
and
```
ADD https://github.com/multiarch/qemu-user-static/releases/download/v2.5.0/x86_64_qemu-arm-static.tar.xz /usr/bin
```
Then the kernel will be able to differ ARM binaries from amd64. When it finds a ARM binary, it will invoke `/usr/bin/qemu-arm-static` first and lets `qemu` translate the ARM syscalls to amd64 ones.
Some code here: https://github.com/multiarch
WDYT is the best approach? If registering `binfmt_misc` in the kernels of the machines is OK, then I think we should go with that.
Otherwise, we'll have to wait for resin's patch to be merged into mainline qemu before we may use the code I have here now.

This change revises the way to provide kube-system manifests for clusters on Trusty. Originally, we maintained copies of some manifests under cluster/gce/trusty/kube-manifests, which is not scalable and hard to maintain. With this change, clusters on Trusty will use the same source of manifests as ContainerVM. This change also fixes some minor problems such as shell variables and comments to meet the style guidance better.
