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.

Thanks,
Nick
