Make php4.2.3 compile on Apache 2.0.39 Linux

[yglodt]

I had to make these changes in the file
php-4.2.3/sapi/apache2filter/sapi_apache2.c

line 567: change to
ap_register_output_filter("PHP", php_output_filter, AP_FTYPE_RESOURCE);

line 568 change to:
ap_register_input_filter("PHP", php_input_filter, AP_FTYPE_RESOURCE);

(remove the "NULL" argument to from both of the functions)
