This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.

According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.

C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."

Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

1. Increased sleep time from 25ms to 50ms
2. Added sleep to shutdown handlers

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.

* PHP-5.5:
  Handle NULL strings in sapi_cli_server_register_variable().
  Allow CLI server test scripts to specify the name of the router file.

Conflicts:
	sapi/cli/tests/php_cli_server.inc

This is required to write tests that behave differently when an index.php isn't
present in the document root. (Such as the one I'm about to commit.)
