When adding tags to a native cc_library rule that is created through a macro we
were not properly considering the case where the tags came from a different
file and therefore were frozen. This caused an error.

Order of libraries should be topological sort when constructing depset for
LinkingContext.
Also remove condition that failed when it shouldn't with a valid combination of
libraries.

We need @rules_cc in front of the toolchain type in cc_shared_library. This is
still experimental.
More complete test suite is on the way in a separate CL I'm working on.

We use BUILD example added in previous CL and inspect the resulting *.so files with nm.
Also fixes implementation of shared library to work with Bazel after having flipped the legacy whole archive flag. This caused exported libraries to be dropped by the linker unless they were alwayslink.
Still more tests to come.

This is only tested with Bazel at head. We modify the presubmits file so that we don't use release. The reason we don't use release is because we need very recent changes to Bazel to test cc_shared_library. In the future we will also test with release.
Also in following CLs, we will inspect in integration test the *.so output from these example builds to make sure that the correct symbols are linked statically and are visible.
After that we will add Starlark unit test to check error conditions.

Add an explicit export statement (with the same visibility) for
files that are currently only implicitly exported and used by other
pacakges. This prepares changing the visibility of implicitly-exported
files to be package private without causing a breakage.

We're working on removing C++ toolchain autoconfiguration logic out of Bazel,
and moving towards using rules_cc repository for it. Some bzl files will no
longer be available through bazel/tools/cpp/*, but through
@rules_cc/cc/*.

Fixes:
* Enabled buildifier on the Bazel CI again
* Added Skydocs where missing
* Moved public files out of .../private/... (e.g. cc_toolchain_config_lib.bzl)
* Reformatted
* Removed unused loads
* Using relative labels for cc_configure related files
* Added development dependency on rules_proto
* they're not in the federation yet, so hand rolling in rules_cc's WORKSPACE file
* Added development dependency on rules_python (from federation)
* Cleaned up copybara (notable change - not using @rules_cc in labels inside rules_cc repo)
* Made cc_flags_supplier usable internally
* Moved load statements to the top of the bzl file
* Moved runfiles to the tools directory
* Unified toolchain_utils.bzl and find_cc_toolchain.bzl

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

We now have copies of .bzl files that we have to keep in sync between @rules_cc and @bazel_tools/tools
I propose to re-enable the Buildifier presubmit once this issue is resolved.
*** Original change description ***
Run Buildifier as part of the presubmit.
As a result we will catch some errors already in GitHub, and not later in Critique when it's harder to fix them.

Here we are duplicating bazel_tools/tools/cpp. The goal is for the BUILD files in bazel_tools/tools/cpp to have an alias that point to rules_cc. Then later on with the incompatible flag these aliases will no longer be valid.
