Remove 3rd party libs from our repository and define the dependencies in composer.json-dist.
Also remove the ancient utf8 lib and replace it with 'Patchwork UTF-8 for PHP'. For direct git checkouts, copy composer.json-dist into composer.json and run `php composer.phar install` to install the dependencies.

- * This class provides an object oriented interface for generating keys with
- * the GNU Privacy Guard (GPG).
- *
- * Secure key generation requires true random numbers, and as such can be slow.
- * If the operating system runs out of entropy, key generation will block until
- * more entropy is available.
- *
- * If quick key generation is important, a hardware entropy generator, or an
- * entropy gathering daemon may be installed. For example, administrators of
- * Debian systems may want to install the 'randomsound' package.
- *
- * This class uses the experimental automated key generation support available
- * in GnuPG. See <b>doc/DETAILS</b> in the
- * {@link http://www.gnupg.org/download/ GPG distribution} for detailed
- * information on the key generation format.
