    Const-correctness in the debug functions!
    
    I'm finding missing constifications all over the place this week.
    Turns out that dmemdump() has been taking a non-const memory pointer
    ever since the beginning, and it's never come up until now. How silly.

    Vary cmdgen's default key size based on key type.
    
    It's a bit silly to have 'puttygen -t ecdsa' immediately crash out
    because the default key size is 2048 and we don't know a 2048-bit
    elliptic curve.

    Support ECDH key exchange using the 'curve25519' curve.
    
    This is the kex protocol id "curve25519-sha256 at libssh.org", so called
    because it's over the prime field of order 2^255 - 19.
    
    Arithmetic in this curve is done using the Montgomery representation,
    rather than the Weierstrass representation. So 'struct ec_curve' has
    grown a discriminant field and a union of subtypes.

    Support public keys using the "ssh-ed25519" method.
    
    This introduces a third system of elliptic curve representation and
    arithmetic, namely Edwards form.
