This test just tests the behaviour of the host sshd in the face of
invalid terminal modes, and the RFCs say that the server "MAY" ignore
such modes (and newer openssh does in fact ignore these modes rather
than terminating the connection).

Add the diffie-hellman-group-exchange-sha256 defined in RFC 4419 to
the list of supported key exchange algorithms for ssh.
The server half is only a minimal implementation to satisfy the automated tests.

This effectively disables the cipher.
Add a test against OpenSSH which sends larger packets through the
tested ciphers. This reproduces the problem reported in golang/go#23510

3des-cbc is an insecure cipher. As such, you must explictly add it to
Config in order to use it.

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.

Move the example tests to an external test package so that they
must explicitly reference the ssh package. The side effect is the
examples now become easier to copy and paste.

The session test previously had a one second timeout for the output of
stty and this was leading to flakiness. This change removes the timeout
since go test has a generic timeout mechanism.
Additionally, the test was looking for "-echo" in the output to test
the value of the echo flag. However, there are also typically "echoe",
"echok" and "echonl" flags, and "-echo" could be a prefix of any of
time. Thus we now also match a trailing space.

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.

This proposal is an attempt to improve the state of functional testing in the ssh package. The previous functional tests required the user to give away some personal details, like their password and private key to run the tests, and so were probably not run as frequently as they should.
