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.

-/**
- * A command-line dummy pinentry program for use with gpg-agent and Crypt_GPG
- *
- * This pinentry receives passphrases through en environment variable and

- *
- * Thie pinentry can be run independently for testing and debugging with the

- *
- * <pre>
- * Usage:
- *   crypt-gpg-pinentry [options]
- *
- * Options:
- *   -l log, --log=log  Optional location to log pinentry activity.
- *   -v, --verbose      Sets verbosity level. Use multiples for more detail
- *                      (e.g. "-vv").
- *   -h, --help         show this help message and exit
- *   --version          show the program version and exit
