Changes in v2: - Fix 32-bit compile - Moved sizeof_rt_sigframe change to its correct patch (patch 2 is the one that extends the size of rt_sigframe, patch 3 is adding new extended state to the frame which is added dynamically).
This series adds vector state to the linux-user signal handler, and adds a basic signal handling test case. As a sanity check, I also verified the signal handling test works in the same way when run under a real Linux kernel. The signal handler test has some gross header hacks in it to make it work for me (debian arm64->riscv64 cross compile environment), I would not be surprised if it breaks in other environments, any ideas or breakages let me know. May just have to define the types by hand for now if it becomes intractable. I couldn't find much in the way of previous discussion or work on this, forgive me if I've missed it.
