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

packet/packet.go: add ECDSA to the algorithms in CanSign()
packet/signature.go: add support for the features subpacket (which is
used to signal support for the MDC packet)
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.
