Samuele Pedroni 00c1479577 x/crypto/openpgp: support crypto.Signer private keys 
This adds support for crypto.Signer-based RSA and ECDSA private keys.
This enables using opaque signing keys as explained in the documentation
for crypto.Signer.

The support is in the form of a new NewSignerPrivateKey function which
makes a PrivateKey from a crypto.Signer.

Fixes golang/go#15841.

Reinaldo de Souza Jr 6318898455 crypto/openpgp: return error from userIdSignatureHash 
Signature#SignUserId was ignoring the error returned by userIdSignatureHash.
This error can happen, for example, when the Signature's Hash property is
uninitialized. Not returning the error makes it hard for the user to detect
the problem.

KB Sriram c10c31b5e9 x/crypto/openpgp: cross-signature validation for signing subkeys. 
Section 11.1 of RFC4880 requires that binding signatures on
signing subkeys contain a valid embedded signature that cross-certifies
the primary key. This is to avoid the weakness described at
https://www.gnupg.org/faq/subkey-cross-certify.html

Fixes #10740

openpgp/read_test.go: add a key generated by End-to-End as a testcase
(End-to-End's keys are unusual: they set critical bits)

Adam Langley 84ca184138 go.crypto/openpgp: fix user id signing. 
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.

Fixes golang/go#7371.
