--//examples:incompatible_link_once=False[default = False]
When True, it will be an error to link the same library more than once
unless it has the tag LINKABLE_MORE_THAN_ONCE
--//examples:experimental_debug=True[default = False]
When True, it will generate files listing the exports of each cc_shared_library
and which libraries are linked to it statically.

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.

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

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.
