The ssh tests currently require 127.0.0.1 to work which isn't
necessarily available everywhere. To fix the source-address tests,
support comma-separated source-address values per the PROTOCOL.certkeys
file:
Comma-separated list of source addresses
from which this certificate is accepted
for authentication. Addresses are
specified in CIDR format (nn.nn.nn.nn/nn
or hhhh::hhhh/nn).
If this option is not present then
certificates may be presented from any
source address.

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.

The current behaviour of the crypto/ssh server implementation is to
remove the username from ConnMetadata if the connection is done without
authentication (NoClientAuth). This appears to be a bug.
This behaviour is different from other SSH server implementations like
for example Paramiko (Python) which keeps the username.
Additionally RFC4252 (https://www.ietf.org/rfc/rfc4252.txt) section
5 states the username has to be included in every USERAUTH message.

Adds a new AuthMethod called "RetryableAuthMethod" which decorates any
other authmethod, allowing it to be retried up to maxTries before
aborting.

The error message reported by the ssh client when it can't find a
"cipher" in common between the client and server was overly vague. This
adds more detailed error messages to findAgreedAlgorithms so that the
user can more easily identify which of the components can't reach
agreement.

Fixesgolang/go#4285.
Adding a new cipher that is supported by the remote end, but not supported by our client causes that cipher to be considered a valid candidate. This fails later in setupKeys when there is no cipherModes configuration.
In summary, unsupported ciphers cannot be willed into existence by adding them to the client config. This change enforces this.

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.

At the suggestion of AGL hmac-md5, and hmac-md5-96
support was not included.

Everywhere else in the code base, when we have an interface{} which is
a stand in for a public key, we use *foo.PublicKey rather than
foo.PublicKey. This change makes ssh reflect that.
