Supporting larger salts makes it possible to implement bcrypt-pbkdf
(http://www.tedunangst.com/flak/post/bcrypt-pbkdf), which is used in
the latest OpenSSH versions to encrypt key files.
This change makes expandKeyWithSalt (and thus NewSaltedCipher) about
20% slower, but since it isn't used in the "heavy" phase of computation
in bcrypt (it uses ExpandKey, which didn't change), the effect on
bcrypt performance is negligible.
The 16-byte limit was an artifact of optimization and due to the fact
that it was enough for bcrypt; Eksblowfish spec or other
implementations don't limit the salt size.
Additionally, there was a bug in the previous implementation: it only
generated correct results for salts consisting of 4, 8, or 16 bytes, and panicked if salt had zero length.

There doesn't appear to be perfect behaviour for line editing
code in the face of terminal resizing. But this change works
pretty well on xterm and gnome-terminal and certainly a lot
better than it used to.

Currently the ssh/terminal package cannot be compiled under gccgo. Even though gccgo may be running on linux, its syscall package is slightly different and does not contain these constants.
This proposal resolves the issue by declaring the two constants locally, as we've done for the *BSDs.

At some point in the distant past, crypto.Hash.New() changed from
returning nil when a hash function wasn't provided, to panicing. Some
of the code in openpgp predates this and was still using the nil check.

Validating a public key doesn't return any remaining methods so, if all public keys were rejected, a nil slice would be returned for the remaining methods and authentication would stop.
We could have validateKey return methods, but that wouldn't solve the problem of what to do if the callback returns no keys. In that case we don't have any keys to test.
So this change makes it possible for an AuthMethod to return a nil slice for the remaining methods (meaning "reuse the last list"). It also fixes a scoping bug.

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.

bcrypt didn't allow one, two and three letter passwords which is a
policy decision best left to the user of the code. Some users have
legacy issues which require such short passwords to be processed.

Increase window size for channels (session and tcpip) to 64 *
max packet size (32 KB), which is the same value that OpenSSH
uses. Also breaks out the relevant harcoded constants into named
constants in channel.go.

Transport should not be a ReadWriter. It can only write packets, i.e. no partial reads or writes. Furthermore, you can currently do ClientConn.Write() while the connection is live, which sends raw bytes over the connection. Doing so will confuse the transports because the data is not encrypted.
As a consequence, ClientConn and ServerConn stop being a net.Conn
Finally, ensure that {Server,Client}Conn implement LocalAddr and RemoteAddr methods that previously were exposed by an embedded net.Conn field.

Although the package doesn't attempt to fully support ancient, version
3 messages, supporting v3 detached signatures is fairly easy and some
projects (in this case, Ubuntu) are using them for unknown reasons.

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.

I understand that ssh/terminal can't implement everybodys
favorite keyboard shortcuts, but I think these are very
widespread. They exist not only in Emacs or Readline, but also
in Acme and Sam. Also they almost come for free.
