`p4-fusion` doesn't compile on new version of Xcode because of outdated `zlib`.

Hi,

The current version of zlib vendored in p4-fusion is having some difficult time compiling the project because of fdopen redefinition.

I recently faced a similar problem on one of the other project and the fix was to update to zlib 1.3.1.

Here's an example of the same issue on some other project: bazelbuild/bazel#25124

I am not sure what's the process of updating third-party libraries vendored into the repo.

Thank you!

I would guess, one of the possible ways would be to delegate zlib to Cmake, since it's supported: https://github.com/madler/zlib, so the subsequent updates would be easier.
