d1cd3c8145 Close meta connection socket after cleaning up event structures. 
Epoll doesn't like it when an already closed filedescriptor is being
removed, so we defer closing the socket until after all else is cleaned
up.

30ef2a981e Automatically exchange ECDSA keys and upgrade to new authentication protocol. 
If we don't have ECDSA keys for the node we connect to, set protocol_minor
to 1, to indicate this to the other end. This will first complete the
old way of authentication with RSA keys, and will then exchange ECDSA keys.
The connection will be terminated right afterwards, and the next attempt
will use ECDSA keys.

8132be8fbd Very primitive ECDSA signed ECDH key exchange for the meta protocol. 
Nonces and hash of the ID requests should be included in the seed for the PRF.

03582eb669 Implement ECDSA sign and verify operations. 
Very basic at the moment, doesn't hash the input first,
and uses OpenSSL's DER encoded signature as output.

80b81c00b1 Have tincctl generate ECDSA keys. 
The generate-keys command now generates both an RSA and an ECDSA keypair,
but one can generate-rsa-keys or generate-ecdsa-keys to just generate one type.

feb3f22fff Add PRF to derive key material from the ECDH shared secret. 
It is modelled after the pseudorandom function from RFC4346 (TLS 1.1), the only
significant change is the use of SHA512 and Whirlpool instead of MD5 and SHA1.

8dfa072733 Support ECDH key exchange. 
REQ_KEY requests have an extra field indicating key exchange version.
If it is present and > 0, the sender supports ECDH. If the receiver also
does, then it will generate a new keypair and sends the public key in a
ANS_KEY request with "ECDH:" prefixed. The ans_key_h() function will
compute the shared secret, which, at the moment,is used as is to set the
cipher and HMAC keys. However, this must be changed to use a proper KDF.
In the future, the ECDH key exchange must also be signed.

8c953b1bfe Don't react to escape character in tincctl top. 
Not only the ESC key generates an escape character, but many other keys
do as well, such as arrow keys.

ab4d289faf Make pid files backwards compatible and add address of listening socket. 
The pid is now written first, so that a version 1.0.x tincd can be used to stop
a running version 1.1 tincd.  Getsockname() is used to determine the address of
the first listening socket, so that tincctl can connect to the local tincd even
if AddressFamily = ipv6, or if BindToAddress or BindToInterface is used.

1fe8ba2f06 Delete mtuevent if it is not used. 
Keeping it around prevents ans_key_h() from restarting PMTU discovery.
