Move Bazel docs into versioned directory.

* Move all Bazel docs (excluding main page, search page, and blog)
  into versions/master directory.
* Replace all original pages with redirects.
* Add Jekyll config with default_version setting to specify the default
  version to redirect docs to.
* Add Jekyll config with version_prefix setting specific to pages under
  each version directory.
* Update layouts to generate links to pages for the same version with the
  version_prefix.
* Update Blaze release script to copy docs from
  third_party/bazel/site/versions/master

Changes to follow this CL:

* Separate navigation from layouts so that navigation can be versioned
  as well.
* Add tool for cutting a release of Bazel docs and copies them into a new
  version directory.

-Building Bazel on Windows
-=========================
-
-Windows support is highly experimental. Known issues are [marked with
-label "Windows"](https://github.com/bazelbuild/bazel/issues?q=is%3Aissue+is%3Aopen+label%3AWindows)
-on github issues.
-
-We currently support only 64 bit Windows 7 or higher and we can only compile
-msys2 binaries.
-
-To bootstrap Bazel on Windows, you will need:
-
-*    Java JDK 8 or later
-*    Visual Studio (Community Edition is okay, only `CL.EXE` is needed)
-*    [msys2](https://msys2.github.io/) (need to be installed at
-     ``C:\tools\msys64\``).
-*    Several msys2 packages. Use the ``pacman`` command to install them:
-     ``pacman -S gcc git curl zip unzip zlib-devel``
-
-To build Bazel:
-
-*    Open the msys2 shell.
-*    Clone the Bazel git repository as normal.
-*    Set the environment variables:
-
-```bash
-export JAVA_HOME="$(ls -d C:/Program\ Files/Java/jdk* | sort | tail -n 1)"
-export BAZEL_SH=c:/tools/msys64/usr/bin/bash.exe
-```
-
-*     Run ``compile.sh`` in Bazel directory.
-*     If all works fine, bazel will be built at ``output\bazel.exe``.
