Makes the sapi web server and curl tests more reliable

1. Increased the time for the sapi/cli/tests/php_cli_server.inc to accept connections.
2. sapi/cli/tests/php_cli_server.inc has errors messages and a `stop` function.
3. bug67429.phpt uses the `stop` function to shutdown the webserver before starting a new one.
4. Removed ext/curl/tests/bug48203_multi-win32.phpt test now that ext/curl/tests/bug48203_multi.phpt
   runs on Windows also.
