sh.1: Cross-reference signal(3)

Summary

in the description of trap.

Even though there is a trap -l that lists signal numbers and names, I think it's still sensible to have a manual reference.

Is signal(3) the right reference? C code had better use sigaction(2) instead, or the list might be moved to a new signal(7) page?

I was thinking about porting signal(7) from NetBSD too. I agree, that it would be a better place for the list and for the reference as well.
