Release 4.0.0 (2021-01-21)

Baseline: 37a429a

Cherry picks:

   + a689d67:
     Use getRunfilesPath for run_under executable path generation.
     getRootRelativePath doesn't return a valid runfiles path for
     external source files anymore after the recent external source
     root change. Also, it won't work for external labels either once
     the --nolegacy_external_runfiles becomes default. This fixes
     issue #12545.
   + d90ec67:
     Fix NPE when coveragerunner is not set on the toolchain.
   + 8555789:
     Fix the classic query package-loading cutoff optimization with
     external workspaces.
   + d113d74:
     Update turbine
   + 1489f0f:
     Support Scala3 .tasty files
   + 0d2d95c:
     Update to java_tools javac11 release 10.5 (#12647)
   + a9419f3:
     Fix common prefix for instrumentation filter
   + 84fadcf:
     Fix builds for filegroup targets with incompatible dependencies
   + e43825d:
     Revert "Remove
     --incompatible_blacklisted_protos_requires_proto_info"
   + 082d58d:
     Transform roots along with paths during output deletion.
   + e8835c1:
     AttributeContainer.Large now handles more than 127 attributes.
   + e1e8734:
     Add an env attribute to all test and binary rule classes
   + a87d7ed:
     Take no action to prefetch empty artifacts.
   + 3e969ff:
     Fix a couple of bugs with Incompatible Target Skipping
   + e667082:
     Pass --host_action_env to host options hostActionEnvironment
     attribute
   + 07400c0:
     Add --{no,}autodetect_server_javabase.
   + c833660:
     Only treat "env" and "env_inherit" attrs specially for native
     rules
   + 6a60b30:
     Fix coverage support when using default_java_toolchain. (#12801)
   + 4158a6f:
     Revert JacocoCoverage target to remote_java_tools_java_import
     and add a new target for remore_java_tools_filegroup. (#12813)
   + f6d30cf:
     Add windows_msvc back to conditions in bazel_tools.

New features:

  - Starlark-defined flags can now be shorthanded using --flag_alias.

Important changes:

  - Add --starlark:file option. This adds a capability to the
    (cquery)[https://docs.bazel.build/versions/master/cquery.html]
    feature in `--output=starlark` mode so that the expression to
    format output may
    be specified in a file.
  - Error messages emitted when an action fails are reworked to be
    more informative about the failing action. Some tooling may have
    to be updated as a result.
  - Querying with output=location now allows the relative_locations
    flag to properly display relative locations instead of the full
    path. Fixes #3497.
  - --flag_alias can now be used without
    --experimental_enable_flag_alias
  - Remove no-op `--deep_execroot` flag
  - The BEP uses `AbortReason.OUT_OF_MEMORY` for abort events when
    the build tool is crashing due to OOM.
  - Added flag `incompatible_display_source_file_location` for `blaze
    query location=output` to print the location of line 1 of the
    actual source files instead of the source file targets. Provides
    a solution to #8900.
  - The Starlark json module is now available.
    Use json.encode(x) to encode a Starlark value as JSON.
    struct.to_json(x) is deprecated and will be disabled by
    the --incompatible_struct_has_no_methods flag.
  - The flag `--incompatible_objc_compile_info_migration` is enabled
    by default.  See #10854.
  - The flag `--incompatible_objc_provider_remove_compile_info` is
    enabled by default.  See #11359.
  - Add `relative_ast_path` feature for darwin builds to relativize
    swiftmodule paths for debugging
  - Use proto.encode_text(x) to encode a Starlark value as textproto.
    struct.to_proto() is deprecated and will be disabled by
    the --incompatible_struct_has_no_methods flag.
    Both functions now reject list/dict fields that contain list/dict
    elements.
  - Add --starlark:file option. This adds a capability to the
    (cquery)[https://docs.bazel.build/versions/master/cquery.html]
    feature in `--output=starlark` mode so that the expression to
    format output may be specified in a file.
    See [Configured Query Starlark
    Output](//docs.google.com/document/d/1kL6Tdmp6uLBa9lq_DbUSjIC87glO
    zKIyPoBeF95Rs4c/edit)
  - Flipped --incompatble_proto_output_v2 for aquery.
  - The --incompatible_load_java_rules_from_bzl flag is now a no-op.
  - The --incompatible_load_proto_rules_from_bzl flag is now a no-op.
  - Flipped --incompatible_force_strict_header_check_from_starlark
  - --incompatible_string_replace_count is flipped and removed
    (#11244)
  - Bazel skips incompatible targets based on target platform
    and `target_compatible_with` contents. See
    https://docs.bazel.build/versions/master/platforms.html for more
    details.
  - Bazel returns exit code 36 (rather than 1) if it fails to start a
    subprocess in a local sandbox due to environmental issues, for
    example, if the argument list is too long.
  - //tools/build_defs/pkg:pkg_rpm is no longer built in to Bazel.
    See #11218 for
    instructions
    on how to migrate to the replacement.
  - Javac now supports multiplex workers.
  - The `--default_ios_provisioning_profile` flag has been removed
    (it was a no-op).
  - Add support for using AndroidX dependencies in
    data-binding-enabled targets.
  - Fix data-binding generation for android_local_test.
  - Enable debug_prefix_map_pwd_is_dot feature by default on macOS,
    this passes `-fdebug-prefix-map=$PWD=.` for every compile to
    remove absolute paths from debug info.
  - --incompatible_run_shell_command_string is enabled by default
    (#5903)
  - py_binary now tolerates package paths that contain hyphens ('-').
    Note that such paths might not be importable from within Python
    code.
  - C++ Starlark API requires linker_inputs wrapping library_to_link.
    #10860
  - Toolchain rule is extended with target_settings attribute.
  - --incompatible_restrict_string_escapes=true is now the default.
    Unnecessary backslashes such as "\." in string literals are now
    an error, instead of being silently treated as "\\.".
    To fix the error while preserving behavior, double the backlash.
    However, the error is often a sign that the original code was
    wrong.
  - Propagate instrumented files for transitive sources of
    `android_library` and `android_binary`
  - --local_resources and --incompatible_remove_local_resources have
    been removed. If you've been setting --local resources or
    --incompatible_remove_local_resources=false, you must migrate to
    using --local_ram_resources and --local_cpu_resources instead.
  - Update rules_cc to commit b1c40e1de81913a3c40e5948f78719c28152486d
  - --incompatible_avoid_conflict_dlls=true is now the default.
  - Dynamic execution now uses the new scheduler by default.
  - Dynamic execution now uses the new scheduler by default.
  - The new dynamic scheduler is now the default.
