Release 0.4.0 (2016-10-26)

Baseline: 088bbc6

Cherry picks:
   + b01160c: Stamp Windows release.
   + 2d6736e: Add --no-tty for gpg signing
   + 9b1dfb8: Remove .sig file before gpg signing
   + 81aede1: Reimplement whole archive on Windows

Incompatible changes:

  - Skylark: updating list/dicts while they are being looped over is not
    allowed. Use an explicit copy if needed ("for x in list(mylist):").
  - Bazel now uses the --cpu flag to look up Jvms; it falls back
    to "default" if it can't find a Jvm matching the CPU value.
  - --command_port=-1 to use AF_UNIX for client/server communications
    is not supported anymore.
  - Sandboxed actions can access the network by default, unless their
    target has a "block-network" tag.

New features:

  - Files now have an "extension" property in Skylark.

Important changes:

  - Added a new flag --sandbox_tmpfs_path, which asks the sandbox to
    mount an empty, writable directory at a specified path when
    running actions. (Supported on Linux only for now.)
  - Update protoc-3.0.0-mingw.exe to a working (statically linked)
    binary
  - apple_static_library rule to create multi-architecture static
    archive files from Objc/C++/Swift dependencies on apple platforms
  - JS: Add support for localization with closure managed rules.
  - Create a flag --android_dynamic_mode to turn off dynamic mode
    during the Android split transition.
  - Darwin sandboxing is default.
  - Remove flag --experimental_zip_tree_artifact from j2objc Java
    annotation processing support.
  - A few functions are added to BUILD files for consistency (hash,
    dir,
      hasattr, getattr) with .bzl files, although they are not very
    useful.
  - --watchfs is now a command option; the startup option of the same
        name is deprecated. I.e., use bazel build --watchfs, not
    blaze --watchfs
        build.
