Remove zend_config.h and APACHE symbol

- zend_config.h file is in current code used only on two places and is
  a simple wrapper for including php_config.h instead.
- The APACHE symbol is part of the PHP 3 functionality and is not used
  anymore.
- Some leftovers of the removed apache SAPI removed.
