Move all moduli generation options to live under the -O flag. Frees up seven single-letter flags. NB. this change break existing ssh-keygen commandline syntax for moduli- related operations.

for OpenSSH This adds a simple manual signature scheme to OpenSSH. Signatures can be made and verified using ssh-keygen -Y sign|verify Signatures embed the key used to make them.

private keys, enabled via "ssh-keygen -m PKCS8" on operations that save private keys to disk. The OpenSSH native key format remains the default, but PKCS8 is a superior format to PEM if interoperability with non-OpenSSH software is required, as it may use a less terrible KDF (IIRC PEM uses a single round of MD5 as a KDF). adapted from patch by Jakub Jelen via bz3013; ok markus OpenBSD-Commit-ID: 027824e3bc0b1c243dc5188504526d73a55accb1
