This would be an issue if we added "compat/" to the list of paths the compiler checks for headers no?

Introduce a new "compat/zlib-compat.h" header that we include instead of including <zlib.h> directly. This will allow us to wire up zlib-ng as an alternative backend for zlib compression in a subsequent commit. Note that we cannot just call the file "compat/zlib.h", as that may otherwise cause us to include that file instead of <zlib.h>.
