    Support rsa-sha2-* host keys in Uppity.
    
    As with the userauth keys, there's a localised bodge when sending
    algorithm names, where I just write a couple of extra entries into the
    list when I notice that a key is RSA-typed. Then I arrange that the
    selection of those entries sets the new variable s->hkflags to the
    right value to pass to ssh_key_sign.

    Expose a global list of known host key algorithms.
    
    The information was already centralised in find_pubkey_alg, but that
    had a query-based API that couldn't enumerate the key types. Now I
    expose an underlying array so that it's possible to iterate over them.
    
    Also, I'd forgotten to add the two new rsa-sha2-* algorithms to
    find_pubkey_alg. That's also done as part of this commit.

    Uppity: send SSH2_MSG_EXT_INFO.
    
    This adds the framework to be able to send it in both client _and_
    server (in the post-NEWKEYS slot); it's just that currently only the
    server has anything it wants to put in it.
    
    Uppity now announces its public key type list, which is enough by
    itself to allow it to accept RFC 8332 rsa-sha2-* signatures during
    userauth. (Because the key verification code receives an ssh-rsa host
    key and validates it against the SHA2-based key algorithm structure
    derived from the id string that was sent separately.)

    Support -logoverwrite and -logappend command-line flags.
    
    If it's worth having command-line options to _specify_ a log file,
    it's also worth having options to avoid having to answer an
    interactive prompt _about_ that log file every time.
    
    (Particularly useful when debugging, in which I often want to run a
    zillion instances of the same quite temporary command line that
    involves writing a log file.)
