2015-01-20	handshake: delay method parsing until the sender key has been handled	Matthias Schiffer
	Otherwise fastd won't use the correct peer group's method list for handshakes incoming on generic sockets.

2015-01-09	ec25519-fhmqvc: don't check group order of peers' public keys	Matthias Schiffer
	Skipping this check will significantly speed up startup with many peers. As we now do embedded group order verification, an attacker can't gain anything from small-subgroup attacks, so skipping the check isn't a security issue.
2015-01-09	ec25519-fhmqvc: optimize handshake by using embedded group element verification	Matthias Schiffer
	Using the embedded group element verification allows us to get away without explicit verification, thus needing one scalar multiplication less. This reduces the number of expensive operations needed for a handshake to three: one Galois field square root (for key unpacking) and two scalar multiplications. For this optimization to be secure, private keys must be divisible by 8. This is the case for all keys generated with all but extremely old versions of fastd (pre-0.4). If fastd finds that its secret is not divisible by 8, it will refuse to start now.
2015-01-09	ec25519-fhmqvc: unpack peers' keys only once	Matthias Schiffer

2015-01-06	ec25519-fhmqvc: additional key checks	Matthias Schiffer
	Until now, it wasn't checked if a public key was the identity element. I don't think this mistake allows any actual attacks against the handshake though.
2014-08-24	Merge peer config into peer structure	Matthias Schiffer
	With this refactoring, the structure fastd_peer_config_t is merged into fastd_peer_t, and fastd_remote_config_t into fastd_remote_t. This also means we now create peers directly when reading their configurations, which significantly simplifies the whole reload process, and prepares for some future optimizations like a key hash table. Note: This commit is too big, but I couldn't come up with a nice way to split it into smaller pieces...
