keys_test.go was slowing down my editor because it was getting too
large. It helps to remove the keys of the file as they contain extremely
long lines and large strings.

Note: Some GPG implementation will reorder the packets for you when
exporting keys. This makes it complicated to generate a key for this
test. Should someone have to create a similar key again, look into
gpgsplit, gpg --dearmor, and gpg --enarmor. These keys exist in the
wild too.

Consider the following packet ordering scenario:
PUBKEY UID SELFSIG SUBKEY REV SELFSIG
In this scenario, addSubkey would only consume the REV signature after
the subkey, leaving SELFSIG to be read by ReadEntity, which in turn
would add the last SELFSIG to the UID's signatures, which is wrong to do
because this is a SUBKEY SELFSIG, not a UID signature.
Remove "current" from the ReadEntity scope, it should only be visible
to the UserId packet handling code.
Keep the warning about signature packets found before user id packets.
Without it, I would not have found this bug.
Modify addSubKey so that it consumes all signatures following the SUBKEY
packet, keeping eithier the first valid signature (like we did before)
or any valid revocation.
In a follow-up patch, we can improve this further by keeping the
most recent signature, as suggested by RFC4880:
> An implementation that encounters multiple self-signatures on the
> same object may resolve the ambiguity in any way it sees fit, but it
> is RECOMMENDED that priority be given to the most recent self-

When failing, TestKeyExpiry would output the wrong expected key id. It
would output "Expected key 1ABB25A0" instead of "Expected key 96A672F5".
Avoid this mistake by declaring the variable only once and using it in
the error format.

The existing code was wrongly assuming that UserID packets must be
immediately followed by a Signature packet. However, this is not true.
See RFC4880 11.1:
> Immediately following each User ID packet, there are zero or more
> Signature packets.
This change will ensure that Entities that are not immediately followed
by a Signature packet are read without raising a StructuralError.
Instead, UserID packets that are not immediately followed by a self
signature will be ignored.
Maximum backwards compatibility is retained because revoked UserIDs are
not added to the Entity's identities.
In a follow-up patch, we should probably add these UserIDs to the
Entity's identities too, but not without making sure that the revocation
is also available in the Entity's (or the Identity's) Revocations slice.
This would require adding support for a new Signature Type,
"Certification revocation signature", as defined in RFC 48880 5.2.1.

Previously if you created a new Entity then ran `Serialize` _before_ running `SerializePrivate`, the resulting armored public key was corrupted, giving the error of `unexpected EOF`. This fix signs the public key with the private key upon creation of a NewEntity. Since SerializePrivate only is applicable to entities created with NewEntity per the docs we can also safely remove the signing portion from that function.

The openpgp package promotes bad defaults by not setting the
preferred cipher and hash of new entities created by
`openpgp.NewEntity`.
The preferred hash can be set by passing a `packet.Config`
with a `DefaultHash` set, but the same cannot be done for
the preferred cipher.
This change copies the DefaultCipher into the self-signature, similar to
DefaultHash.

Say the user wants to create a NewEntity, then Serialize the private and public
keys. Then call Encrypt. The Hash used first for Encrypt will be `RIPEMD160`,
which is not compiled in by default. So say they _specifically_ pass
crypto.SHA256 as the Default hash to NewEntity, this should set the
PreferredHash in the SelfSignature so they can be encrypted with that hash.

Entity.SignIdentity used the wrong signature function and produced invalid
certification signatures. Fixed.
VerifyUserIdSignature was used for checking the self-signature on an identity,
but didn't support anything but a self-signature. This change alters the
low-level API so that checking cross-signatures is possible.
