Confusingly, `Identity.Name` should actually refer to `uid.Id` and not
`uid.Name`. This fixes the code in NewEntity, and creates a test case to
verify.

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.
Fixesgolang/go#7371.
