add the ability to query supported ciphers, MACs, key type and KEX
algorithms to ssh. Includes some refactoring of KEX and key type handling
to be table-driven; ok markus@

[packet.c ssh_config.5 sshd_config.5]
add encrypt-then-mac (EtM) modes to openssh by defining new mac algorithms
that change the packet format and compute the MAC over the encrypted
message (including the packet size) instead of the plaintext data;
these EtM modes are considered more secure and used by default.

Refactor internals of private key loading and saving to work on memory
buffers rather than directly on files. This will make a few things
easier to do in the future; ok markus@
[authfile.c key.c key.h ssh-keygen.c]
fix a possible NULL deref on loading a corrupt ECDH key
store ECDH group information in private keys files as "named groups"
rather than as a set of explicit group parameters (by setting
the OPENSSL_EC_NAMED_CURVE flag). This makes for shorter key files and
retrieves the group's OpenSSL NID that we need for various things.

Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and
host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer
better performance than plain DH and DSA at the same equivalent symmetric
key length, as well as much shorter keys.
Only the mandatory sections of RFC5656 are implemented, specifically the
three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and
ECDSA. Point compression (optional in RFC5656 is NOT implemented).
Certificate host and user keys using the new ECDSA key types are supported.
Note that this code has not been tested for interoperability and may be
subject to change.

Add a TrustedUserCAKeys option to sshd_config to specify CA keys that

Add a RevokedKeys option to sshd_config and a @revoked marker to
known_hosts to allow keys to me revoked and banned for user or host
authentication.

Prevent ssh from trying to open private keys with bad permissions more than
once or prompting for their passphrases (which it subsequently ignores
anyway), similar to a previous change in ssh-add. bz #1186, ok djm@

Make ssh-add check file permissions before attempting to load private
key files multiple times; it will fail anyway and this prevents confusing
multiple prompts and warnings. mindrot #1138, ok djm@

markus@ ok
There are also some portable-specific -Wshadow warnings to be fixed in
monitor.c and montior_wrap.c.
[authfile.c ssh-keygen.c]
change key_load_public to try to read a public from:
rsa1 private or rsa1 public and ssh2 keys.
this makes ssh-keygen -e fail for ssh1 keys more gracefully
for example; report from itojun (netbsd pr 20550).
