The previous version does not mark the `toolchain_type` as public,
meaning that users of a CC toolchain using
`@rules_cc//cc:toolchain_type` will get build errors along the lines of
```
ERROR:
.../local_config_cc_toolchains/BUILD.bazel:18:1:
in toolchain rule
@local_config_cc_toolchains//:cc-toolchain-armeabi-v7a: alias
'@rules_cc//cc:toolchain_type' referring to target
'@bazel_tools//tools/cpp:toolchain_type' is not visible from target
'@local_config_cc_toolchains//:cc-toolchain-armeabi-v7a'. Check the
visibility declaration of the former target if you think the dependency
is legitimate
```
We've notice significant issues downloading from zlib.net. Since there
are already other archives coming from GitHub, this shouldn't negatively
affect reliability.
When the @six//:six library is used on a target without the
`legacy_create_init` flag disabled, the library will not be
usable due to __init__.py being empty and the six code will
be in six.py. This change forces six to occupy the __init__
name, preventing this file getting created regardless of
the `legacy_create_init` setting.
See comments on a74c43bbd9 for
context:

This change adds the required loads to examples and zlib.
For full compatibility with --incompatible_load_{cc,java,proto}_rules_from_bzl,
we will need to roll gtest to a newer version.
