This patch introduces a smart way to generate and keep in sync the host-to-guest and guest-to-host signal conversion tables for usage in the qemu signal and strace code. This ensures that any signals will now show up in both tables. There is no functional change in this patch - with the exception that yet missing signal names now show up in the strace code too.
