Add support for Docker for MacOS
With Docker for MacOS [public beta](https://docs.docker.com/docker-for-mac) you don't need docker-machine on MacOS to build kubernetes instead you can use docker "natively". Per Default Docker for MacOS will be installed to `/Applications/Docker.app/Contents/MacOS/Docker` so if Docker for Mac is installed we should use the native version.
I tested it locally with `15.5.0 Darwin Kernel Version 15.5.0` and Docker version `1.12.0-rc2`

Auto generated docs are **NO LONGER CHECKED IN**, only placeholders.
To generate them, e.g. before exporting docs, run hack/generate-docs.sh.
hack/verify-generated-docs.sh ensures that generated docs are merely the
placeholder text.
hack/update-generated-docs.sh puts the placeholder text in the proper
places.
The old munge behavior is moved into hack/{update|verify}-munge-docs.sh.

Change GCI and trusty cluster-helper scripts to use kubedns instead of skydns.
Unified skydns templates using a simple underscore based template and
added transform sed scripts to transform into salt and sed yaml
templates
Moved all content out of cluster/addons/dns into build/kube-dns and
saltbase/salt/kube-dns

Support for cluster autoscaler in GCE Trusty and GCI images

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.

Reimplement 'pause' in C - smaller footprint all around
Statically links against musl. Size of amd64 binary is 3560 bytes.
I couldn't test the arm binary since I have no hardware to test it on, though I assume we want it to work on a raspberry pi.
This PR also adds the gcc5/musl cross compiling image used to build the binaries.
