[RFC] [Declined] UUID

Hey Internals! The UUID RFC [1] was now officially declined. Some of you might ask themselves what's going to happen next. Well, I will most probably move it to PECL after a little overhaul where I incorporate the latest feedback I got on the PR. After that I also hope to see some progress on the C+PHP front. I might revive the namespace topic after gaining some strength and free time, and hopefully we can create a real standard collection in PHP for a better future. We'll see. Thanks to all the voters and people who gave feedback. It was a ride, but that was to be expected. [1] https://wiki.php.net/rfc/uuid
