GSOC proposoal: Write an updated Guide on extending PHP

There are already empty placeholders for this kind of informations in the PHP documentation. These could be filled. Sara's book is a good start, but it could be updated to wash out all PHP4 stuff and put in new things developed since then. Some more informations on memory management would be fine: - How to deal with libraries that have there own memory management? - Some workflows for debugging What's best practice? I'm not that comfortable with copying stuff from other extensions, since I don't know if I'm copying legacy stuff. An example extension would round it up.
