zlib fork

This uses a fork of zlib, which is at https://github.com/joeyparrish/zlib/tree/preview

We forked from upstream https://github.com/madler/zlib and merged the following PRs:

• https://github.com/madler/zlib/pull/519, which contains code from https://github.com/Togtja/zlib/tree/optional_zconf_rename. This gives us an option to disable zlib's default CMake behavior of modifying the working directory during configuration. This helps to keep the submodule clean.

• https://github.com/madler/zlib/pull/691, which contains code from https://github.com/joeyparrish/zlib/tree/optional_tests. This gives us a way to disable zlib's test targets.

When these PRs are merged, the fork can be deleted.
