This adds a built-in function to generate UUIDs. PostgreSQL hasn't had a built-in function to generate a UUID yet, relying on external modules such as uuid-ossp and pgcrypto to provide one. Now that we have a strong random number generator built-in, we can easily provide a version 4 (random) UUID generation function. This patch takes the existing function gen_random_uuid() from pgcrypto and makes it a built-in function. The pgcrypto implementation now internally redirects to the built-in one.
