Summary: there's a check beneath to see if it worked, but @require_once will
fail silently if libphutil isn't available
Test Plan: tried it with libphutil findable and not findable, got expected
behavior

Summary: See D589. Some environments configure output buffering with a prepend script. This is rather silly, but we can at least recover from it.
Test Plan: Started multiple output buffers with ob_start() and then used phutil_console_confirm() to create a prompt. Verified that 'arc' was broken under output buffering prior to the patch, but now works correctly.
