rr supports the "bs" gdbserver packet to reverse-step a single instruction (and so does the test proxy I'm adding here). To "reverse-next one line" we will need to implement a thread plan that uses a combination of reverse-step-instruction and reverse-continue-to-breakpoint. That's future work. It may be difficult, and it's also not very high priority because it tends not to get used very much by gdb users.
