Description:
------------
It seems the latest version (10.13) of macOS has broken the capability to get and set process titles. Using cli_get/set_process_title results in a warning. The way to fix this would be to use the OS-provided methods, which libuv from the nodejs project has implemented in https://github.com/joyent/libuv/commit/14eb8b0 and https://github.com/joyent/libuv/commit/e89aced

Test script:
---------------
<?php
cli_set_process_title('test');
echo cli_get_process_title();

Expected result:
----------------
test

Actual result:
--------------
