Similar to the previous CL, this CL is to ensure that we agree on the relationship between each different type.
This will also allow for developing two things in parallel:
* The rules that generate these providers.
* Toolchain validation, and conversion to the cc_toolchain_config_lib providers.

As of Bazel 6.0.0, all Bazel-provided toolchains report consistent
compiler names that can be matched on with `select`. Having a central
place for `config_setting`s that can be used for this purpose makes it
so that rulesets don't have to define them themselves and moving the
compiler flag out of `@bazel_tools` becomes easier as it is no longer
referenced directly.
Also includes minor fixes to `//tests/...` so that it can be enabled in
CI.
Right now there should be no difference between `cc_host_toolchain_alias` and `cc_toolchain_alias` rules.
This is a potentially breaking change for Bazel, if something was depending on `current_cc_host_toolchain` try depending on `current_cc_toolchain` instead.

Remove redundant tags for copybara to replace labels with labels including the

Numerous tools override --custom_malloc to add debugging or monitoring runtimes
(see e.g. sanitizers). While this is fine for cases where the tool must also
override malloc to function, in other cases it's simply misuse of
--custom_malloc where no other mechanism exists to link an extra library.
This becomes especially problematic where a runtime library is supposed to be
added in certain configurations that should run in production or other
performance sensitive builds. In these cases, we should _not_ override malloc,
which may also be specified by a cc_binary target. Doing so would introduce
unwanted changes, potentially affecting performance negatively.
This is the @rules_cc counterpart to the equivalent Bazel tools flag
--@bazel_tools//tools/cpp:link_extra_libs. Users that use @rules_cc to build
their C++ projects may use both flags interchangably, however, the @rules_cc
flag should be preferred.

Simplify WORKSPACE setup and update ancient deps
By removing a single unused `bzl_library` target, rules_cc no longer has
any dependencies that would need to be loaded by a dependency macro. The
existing macro is made a no-op.
The few needed Bazel Federation dependencies are inlined and, in the
case of bazel_skylib and abseil-py, updated to modern versions.
Also reorders `WORKSPACE` to list direct dependencies first and keeps
`MODULE.bazel` in sync with the dependency versions used in WORKSPACE.
The `ubuntu1604` CI pipeline is removed as the version of Python used by
it is no longer supported and the distribution is EOL. Instead, a new
pipeline is added to check the Bzlmod build.

*** Reason for rollback ***
Broke a test
*** Original change description ***
The auto-configured toolchains provided by Bazel itself have diverged heavily from the version maintained in this repo. There is no need to maintain this duplication until Starlarkification has progressed succiciently for rules_cc to be the source of truth for them.
This is particularly relevant for Bzlmod, which currently uses the toolchains defined in rules_cc. As a result, Bazel C++ builds will use subtly different toolchains depending on whether --enable_bzlmod is used or not. This is fixed...

This is particularly relevant for Bzlmod, which currently uses the toolchains defined in rules_cc. As a result, Bazel C++ builds will use subtly different toolchains depending on whether --enable_bzlmod is used or not. This is fixed by loading toolchain detection logic from @bazel_tools in the module extension.

The version has never been updated since the first release and since rules_cc is currently a slim wrapper around Bazel-provided rules, version detection shouldn't be necessary.
Instead, add an alias to the Bazel-provided runfiles library under //cc/runfiles, following https://bazel.build/rules/deploying.

- Use a newer version of rules_go for our internal rules.
- Make a bzl file used in a test visible to the tests.

These are used throughout the Crosstool features definitions based on local definitions there. It seems useful to move these to a common location so they are available for other toolchains (and also so that they get updated if new actions are added to the action-name list).
The versions of these currently used by Crosstool are defined in //third_party/crosstool/v18/llvm_unstable/crosstool_helpers.bzl starting at line 124.

This allows setting GCOV on the command line to overwrite the default setting, which points to /usr/bin/gcov. In order to use this, you also need to disable the gcov coverage feature and enable the llvm coverage feature instead. The full command-line looks like this:

This commit allows the creation of distributions, with 0.0.1 being the first version.
See distro/README.md for details on how to build a release.
This commit also uses a new version of the Bazel federation that contains rules_pkg 0.2.2 instead of 0.2.1.
There are still some problems with the WORKSPACE stanza that is being printed by the release notes generation script, though:
- It references a //cc:deps.bzl file, which doesn't exist. I have to modify the scripts in rules_pkg to support a flag like 'has_deps'.
- It doesn't support the Bazel federation yet, since it always tells users to download code from the rules_cc repository.
BEGIN_PUBLIC
Remove unused load statements from .bzl files
After transitive loads have been disabled in Blaze, unused load statements have
no effect (besides not useful memory consumption).
The CL has been created automatically by calling `buildifier --lint=fix --warnings=load` on all .bzl files.
The following additional command were run on all affected files to clean them up:
* buildifier -a -v --lint=fix --warnings=load-on-top
Moves all load statements to the top of a file
* buildifier -a -v --lint=fix --warnings=same-origin-load
Compresses all load statements from the same .bzl file to one load statement
