Change the encoding of key types to have a parity bit

Change the encoding of key types, EC curve families and DH group
families to make the low-order bit a parity bit (with even parity).

This ensures that distinct key type values always have a Hamming
distance of at least 2, which makes it easier for implementations to
resist single bit flips.
