+Flag-day changes: (things which are backward incompatible)
+ . remove link key from directories, from connection_t.
+ (just get it from the tls cert)
+ . make onion keys include oaep padding, so you can tell
+ if you decrypted it correctly
+ . add bandwidthrate and bandwidthburst to server descriptor
+ - directories need to say who signed them.
+ - what other pieces of the descriptors need to change?
+ maybe add a section for who's connected to a given router?
+ add a flexible section for reputation info?

Bugs:
o we call signal(), but we should be calling sigaction()
o send socks rejects when things go bad ?
