All the main backend structures - Ssh, Telnet, Pty, Serial etc - now describe structure types themselves rather than pointers to them. The same goes for the codebase-wide trait types Socket and Plug, and the supporting types SockAddr and Pinger. All those things that were typedefed as pointers are older types; the newer ones have the explicit * at the point of use, because that's what I now seem to be preferring. But whichever one of those is better, inconsistently using a mixture of the two styles is worse, so let's make everything consistent. A few types are still implicitly pointers, such as Bignum and some of the GSSAPI types; generally this is either because they have to be void *, or because they're typedefed differently on different platforms and aren't always pointers at all. Can't be helped. But I've got rid of the main ones, at least.
