This changes Signature so that parsed signatures can be reserialized
exactly. With this ability we can add Serialize to Entity and also the
ability to sign other public keys.

This change adds a function for generating new Entities and inchoate
support for reserialising Entities.

* Accept armored private key blocks
* If an armored block is missing, return an InvalidArgumentError,
rather than ignoring it.
* If every key in a block is skipped due to being unsupported,
return the last unsupported error.
* Include the numeric type of unsupported public keys.
* Don't assume that the self-signature comes immediately after the
user id packet.

Note that DSA public key support is nascent and the verification
functions clearly don't support it yet. I'm intending to get RSA keys
working first.
