FTP support installation

To enable FTP module support in PHP3:

- download PHP3 http://www.php.net
- untar "tar -xf php-3_0_16.tar"
- install RPM for apache (*.h): "rpm --install apache-devel-1.3.12-2.i386.rpm"
- in PHP3 src dir exec configurator "./configure --with-ftp --with-apache=/usr/include --with-apx"
- run make
- PHPInfo() function returns all parameters of ./configure
- ftp_xxx functions now work
