Release 2.2.0 (2020-03-03)

Baseline: 78055efad0917b848078bf8d97b3adfddf91128d

Incompatible changes:

  - The --[no]incompatible_windows_bashless_run_command flag is no
    longer supported. It was flipped in Bazel 1.0
  - The --[no]incompatible_windows_native_test_wrapper flag is no
    longer supported. It was flipped in Bazel 1.0

Important changes:

  - Consistent target naming style in example target names.
  - cquery's config() now supports arbitrary configurations.
  - The flag --incompatible_disallow_dict_lookup_unhashable_keys is
    removed.
  - Include target label in Python version error message.
  - The flag --incompatible_remap_main_repo is removed.
  - Windows: we now discourage running Bazel from MSYS2 because of a
    newly found bug (#10573)
  - Reduced the packaging time (`package-bazel.sh`) for the
    `//src:bazel-dev` Bazel development build target from 14s to 6s.
    Use `//src:bazel-dev` if you're iterating rapidly on a local
    Bazel changes, and use `//src:bazel --compilation_mode=opt` for
    release builds.
  - cquery: "//foo:bar" now means "all configured targets with label
    //foo:bar" instead of "choose an arbitrary configured target with
    label //foo:bar". See cquery docs for details.
  - WORKSPACE and BUILD.bazel files of http_archive repositories can
    now be patched using the "patch_cmds" and "patches" attributes.
  - Actions with "parse" on the critical path should no longer finish
    in the future.
  - Flags that affect external repositories like
    "--override_repository" can now be addressed in bazelrc files
    using the "common" command, without causing commands like "bazel
    shutdown" to fail.
  - The flag --incompatible_disallow_unverified_http_downloads is
    removed.
  - Create the incompatibleApplicableLicenses flag.
    We plan to flip this from false to true in Bazel 4.x.
    Implementation to follow.
  - Treat .cu and .cl files as C++ source. CUDA or OpenCL are not
    natively supported and will require custom flags to compile with
    e.g. clang.
  - Treat .cu and .cl files as C++ source. CUDA or OpenCL are not
    natively supported and will require custom flags to compile with
    e.g. clang.
  - The --starlark_cpu_profile=<file> flag writes a profile in
    pprof format containing a statistical summary of CPU usage
    by all Starlark execution during the bazel command. Use it
    to identify slow Starlark functions in loading and analysis.
  - --ram_utilization_factor will be deprecated. Please use
    --local_ram_resources=HOST_RAM*<float>
  - Docs: glob() documentation is rewritten, and now it points out a
    pitfall of rules shadowing glob-matched files.
