When implemented by ssh.PublicKey types, the new CryptoPublicKey
interface exposes the public key in the the crypto.PublicKey form via a
CryptoPublicKey() method.
This is useful for example in a custom ServerConfig.PublicKeyCallback
function to check or record additional details about the underlying
crypto.PublicKey

RSA and DSA keys if encrypted have the
phrase ENCRYPTED in their Proc-Type block
header according to RFC 1421 Section 4.6.1.1.
This CL checks for that phrase and errors out
if we encounter it, since we don't yet have
decryption of encrypted private keys.

Added support for parsing the "new" openssh private key format.
(ed25519 keys only in this format for now)
Signing and verifying functions now work with ed25519 keys.
ed25519 can now be accepted by the server to authenticate a client.
ed25519 can now be accepted by a client as a server host key.

This adds a NewSignerFromSigner to crypto/ssh which takes a
crypto.Signer and turns it into an ssh.Signer, helpful if, e.g., your
crypto.Signer is backed by some sort of hardware device.
The interfaces are very similar - the biggest differences are that a
crypto.Signer accepts hashed data, while an ssh.Signer does not, and
some differences in encoding for DSA and ECDSA signatures.
This also adjusts NewSignerFromKey to use NewSignerFromSigner where
possible, dropping the rsaPrivateKey and ecdsaPrivateKey types in
favor of wrappedSigner. (However, because *dsa.PrivateKey is not a
crypto.Signer, we still have to keep dsaPrivateKey)

Change parseECDSA() to unmarshal the key's contents into a struct
representing the wire format, consistent with the parseRSA() and
parseDSA(), to make the code more readable and its intent clearer.

The change to add the PublicKey interface accidentally caused certificate handling to expect an extra copy of the private key algorithm name in the binary representation. This change adapts a suitable parsing API and adds a test to ensure that cert handling isn't easily broken in the future.

These are the cosmetic cleanups from the bits of code that I
rereviewed.
1) stringLength now takes a int; the length of the string. Too many
callers were allocating with stringLength([]byte(s)) and
stringLength only needs to call len().
2) agent.go now has sendAndReceive to remove logic that was
duplicated.
3) We now reject negative DH values
4) We now reject empty packets rather than crashing.
