UpdateHostkeys on the server side. The previous code tried to prefer RSA/SHA2
for hostkey proofs of RSA keys, but missed some cases. This will use RSA/SHA2
signatures for RSA keys if the client proposed these algorithms in initial
KEX. bz3375

If the platform has a native SHA2, does not define SHA.*_BLOCK_LENGTH
but does define SHA.*_HMAC_BLOCK_SIZE (eg Solaris) then use the latter.
Should fix --without-openssl build on Solaris.
Allow control over which pubkey methods are used. Added out of
concern that some hardware devices may have difficulty signing
the longer pubkey authentication challenges. This provides a
way for them to disable the extension. It's also handy for
testing.

Require host-bound userauth requests for forwarded SSH connections.
The hostkey parsed from the host-bound userauth request is now checked
against the most recently bound session ID / hostkey on the agent socket
and the signature refused if they do not match.

Add kex->flags member to enable the publickey-hostbound-v00@openssh.com
authentication method.
Use the new hostbound method in client if the kex->flags flag was set,
and include the inital KEX hostkey in the userauth request.
Note: nothing in kex.c actually sets the new flag yet

This is identical to the standard "publickey" method, but it also includes
the initial server hostkey in the message signed by the client.

allow authentication methods to have one additional name beyond their
primary name.
allow lookup by this synonym
Use primary name for authentication decisions, e.g. for
PermitRootLogin=publickey
Pass actual invoked name to the authmethods, so they can tell whether they
were requested via the their primary name or synonym.
