Add php pdflib PECL extension package version 1.0 - PHP extension for
PDFlib on-the-fly PDF generation. This replaces php4-only php4-zip.

While there is newer version available in PECL (2.0.2 ATM), it doesn't
build with PDFlib 4.x, so we use version 1.0, i.e. the same version
which ships with PHP 4.3.9.
